beautiful girl guys there are various methods to remove rust there are various videos but this time we will talk about a method made up of several phases which unlike red methods such as hydrochloric acid and others and also electrolysis because it has the unlike these, of course, it was not to ruin the piece and to get to the point that if we also have the nets I laughed that the small amount of rust remains, let's say, reduced to iron because the electrolysis putting the iron object on the negative produces practically a reduction of the oxides that are of the rust it makes spongy iron so it is not that it is more resistant iron but the more resistant of the rust and it is not closer however you have to remove the rust first as much as possible without damaging the object now we have an example a small attraction lock such as those of the windows of the past was made by hand they are only by fabro for some time also a finesse of this chiellino the spring completely riveted here behind then first of all what many do not do you have to remove any grease impregnation and there are some you do not see there are shock awards and living nice in this case you see which does not allow the action of the subsequent phases does not allow to remove the rust because it does the shielding and also the grease slows down any chemical electrochemical action belgium the first thing is this thing how we do simple cleaning with caustic soda be careful an important thing when you can these cans of caustic soda is nothing special but also very dangerous for the eyes it would take glasses and gloves but above all when the pritt and especially if you have shaken to break that large entrance not approached by the face this mouth because you get a very fine smoke of dust the sun goes down expired to burn your eyes sneezing these things here then let's say two glasses of water we put two tablespoons of caustic soda even fewer people we put them o 22 scarce in order to speed up this process this procedure will cause the residual varnishes to melt the grease involved in the rust also it will melt it will turn into soap so now we mix and wait for it to melt while it defines liszt to melt its caustic in some cases as you can see the rust that comes off is convenient to remove and jack only there is the penalty in via little civilization with a brushed mentality if the object is delicate with this that all brass and does not ruin the metal and cross escape the profile the one he sent you because it is useless to do to carry out a clinical work complete with chemicals for something that was able to be removed initially so then we only remove two red clearly the bulk of the work and then the chemistry will be finished ok
so we pour our sodium hydroxide solution that is people caustic on our object and we let it rest never choose its from kaos very hot dinner because it will overheat it starts to mean it is better neither lukewarm or cold water now leave here slowly what I said the caustic soda will melt if we leave it for ten years in this solution it absolutely does not affect the iron it can stay ten years it will remain as it is, on the other hand, it attacks the aluminum very voraciously and then attacks the lead, the tin, the zinc so if you have an object with watertight tour and use little caustic soda for a short time or do not use it because the hero can ruin it as you can see already knows social there is also a little rust if it is going away here we are I would say that we can remove rinse them when you use its caustic and always a blackberry for interruption have a container with clean water to wash your hands even if it ends up in face to rinse but it is not enough because you will feel that touching the caustic soda removes the sensation of slimy this is because it is attacking the skin turns it into soap already à when he hasn't gone away yet he lets a lot but there is a fantastic trick he always had vinegar not too strong and at hand in a moment it disappears i.e. the vinegar combines with the hydroxide usually they had agreed to sodium that does not do is not corrosive is not harmful it goes away is a very useful thing also for then it is thorium from the traces of caustic soda from the piece after rinsing another thing if it runs out of caustic soda like above take a piece of paper and the tower of the remove you are not here if a place happens where then you no longer have to touch that a window sill gets wet for in fact something on the window leave the cure because with the carbonic minutes of the area in a few hours it will turn into carbonate sodium or normal soda to wash bottles and it is no longer aggressive now we want our piece and rinse it then if we want we can help ourselves a little vinegar neutralize the residues of neighbor of stories but also in the water with The self-making sofa here we see a little it already comes off a little with the hands even the paint is on and then we remove all this from the hands if you want you can also brush a little bit of rust has gone from with these so milito now let's move on to the second phase then phase two of the capagno with hydrochloric acid then if it is something very very originated something red above all you can use the concentrate that is found from the hardware store is a consideration about 33 percent but not whole a dedicated piece we will use that of the supermarket that the configuration varies from 5 to 15 percent and does not produce children because instead the concentrated one produces fumes that can then be used in the environment as luigi nieri and iron objects and similar stuff . you were to touch this diluted is not very dangerous and almost the gastric injuries of the stomach and if you were to touch the preci touch an earthed object that you rusts immediately therefore it also ends up in the eyes or face always a container with pure water and in this case ammonia ammonia very diluted less than 5 percent from the supermarket that you can wash your hands this immediately neutralizes the hydrochloric acid does not attack the skin because it is diluted and turns into sodium chloride to hydrochloric acid with harmony in the hem please excuse harmony seduction salt harmless then we pour our hydrochloric acid this phase of hydrochloric acid is a phase that must be kept under control because otherwise you are the king of the corroded piece precisely that for delicate pieces it is better to use a delicate acid now he will work slowly eaten of iron hydroxide oxides iron carbonates that make up the rust and will return in all yellowish iron, however, remaining there at a certain point also the iron begins to corrode so it must always be kept under control and you do not need to the iron will appear a lot the rust will disappear you have to stop because you continue to eat the rust but removing the blade will also corrode the iron so you will pass to a third phase the iron begins to appear a little in certain points however we wait let it go away from most of the rust see you soon here the iron begins to appear recently we will stop but before doing a little more go inside let's rinse our piece with ammonia errors and since the rust you see has been clearly weakened by fatty acids yes cala al khali first we can take advantage of it to lend a hand physics with mechanics that is to see how many go away mc just go away a little we speed up the process and now leave some remittances it seems ok then we have left it too much if an object is more delicate you have to wait and see when the metal begins to appear and stop there you see that the solution this paper cl yellow ferric oruro if you can concentrate many nintendo acts to rust you can keep that famous liquid that you need to make printed circuits then now when you rinse it and we neutralized it with ammonia in the horizon the water underneath is clearly resting on the bottom he did not work much, it will be necessary to have some spacers a little more than the higher one but we have not covered it has remained as it is now this is only an example then leaving the race they are not books so it finishes corroding the rust but starts from sil iron it corrodes it corrodes the iron leaves a sediment in the rod of the greenhouse iron like this no almost nothing because very sweet iron practically contains very little carbon a piece of steel leaves a lot of black dust which is what indicates that it is corroding because it is the carbon that the content in the steel this little carbon so you can see that even here it is metal color while with the steel the same piece of blackish powder and the star left on the bottom of the container then at this point we switch to another acid which would be phosphoric acid by eye I put about a quarter of phosphoric acid from 85 percent and the remaining water then in its we put back in the bathroom of our lock the phosphoric acid is a weak acid and up to the beginning in the coca cola to give that hope for cheaper acidity clearly than the citric acid of the tartaric asylum for what they use it unique among other things you can also taste cramped very good seemed right citric acid warms the tongue leaves that strino pelacci dino very good clearly 85 per cent it is not having then seen the tip on the tongue tasted it is not poisonous at this point the phosphoric acid unlike the lithic acid attacks the rust with or rust is not very fast but I run rust and leave it alone the iron does not attack it but it needs its time we can also leave it the days in there but we will not have a minimum corrosion of the iron and I recommend leaving it with these proportions between it depends on how much rust there is to say between 5 and 20 hours something like this you go to see every now and then and therefore now the we will leave here we will see each other when the iron phosphate solution that is taken out of the oven had worked it is not very colored little colored it worked it left me about 16 hours behind still as they say if the product of the fact that it supported it worked little but we left some small cubes of rust because it remains inside the pores and takes longer to wear out but at this point we will empty the thumbs and remove it, leaving it still but I want instead to transform that rust that remains closed in the spongy iron pores so here we will move on to the other phase that of 'electrolysis then I put you in this one here there are about two glasses nails king half put three tablespoons of bicarbonate in hot water or warm liquid hot because it melts first and we now put a kitchen of ammonia because it has noticed one other times so I do gando that it seems that the speed of the process increases now the curiosity we have mentioned in the books on concentrate and let's go to the curiosity in the bathroom a myth of ammonia more my finger but in the presence of some solar cell gas the coke comes out of the water contained in the solution what happens this that plates laughs with a gas is dissolved in water but continues to come out especially when ammonia is concentrated is a dissolved gas in water and in fact the advocate comes out when the two gases combine with each other they react and form chloride from the olives in very small crystals the smoke you have seen are very small crystals of my wife's very fine chloride that float in the air then a perfume that makes the wife we put our piece in here we connected to the negative of a power supply it is fine 12 15 times we pace of the kind that also regulates bile in current you will find it in the description of the video nor will there be the inter every now and then we put things that we use in the videos then for both one night our solution of water and bicarbonate more or less dissolved from a drop of ammonia to the letters positive do we put a common piece of iron then the electrolysis works so that by putting this iron in contact with water a current of electrons passes from the negative to the positive on the negative which is the seat of this lock hydrogen is formed while on the positive one oxygen can arrive 4th gen a lot says a lot of oxygen because as they say why the letters of the little one while they are all thumbs attached reader or frost on the lock then what happens the iron this does not corrode that of carbonates you can also use caustic soda but it is faster because it passes small integer in diminished chemical adage better because analysts shorter life however for convenience each one there carbonate does nothing you can do t rquillamente take in hand and what happens the hydrogen that forms on the rust reduces the rust that an oxide a hydroxide of ours mixed the carbonates will have to reduce spongy metallic grasp then putting this is a certain time maybe with a support leaving it here so then moving it putting it this way this rust that remains between it will turn black go now let's speed up the procedure for a moment to show you what happens then put a filter here on this on this electrode here and I say this because it can also be used in practice if you have to retouch certain small bubbles of rust then with this we go punctually on the points and we allow ourselves the current of and we do a lot before doing the whole bath and leaving it then we remove potro viani we wet our center of bicarbonate water comes here it fry so we go for example on this rust know that with wet hands of a saline solution such as bicarbonate water even with fifteen times without a slight shock not annoying especially if you have some cut on the firm is becoming it I was practically not that it removes the rust iron pores remain full that becomes black or at all contact feel it clicks there is the current control system then nothing happens while if you have a different power supply or use a battery or a tx computer power supplies you have to put in series a 20 watt light bulb from the 20 watt ones and from the arrows of the cars that will allow that when you make a short circuit like now I can no longer do it here when you make a short circuit they do not burn the wires do not happen it is dangerous the light bulb turns on everything is fine even a bathing light bulb to have stronger currents then you see it is turning black 40 gr current then circulates everywhere and aneri choose occupies still not black this oxide here we insist on him here he is becoming the hero too and doing this job gold we do not go to completely empty the pores and they will remain very full they would remain if you leave the phosphoric in the phosphoric seat even two days in the evening it is beautiful of the cavities but I want to obtain the iron jabs for example while here still reddish which meanwhile black here has become black converted to spongy metallic iron is clearly unfortunately not solid another thing is a piece is very tap like this there are even worse do not expect to find a stupendous shiny surface now it is rust things and iron oxide and this iron that contains the reggina from where it takes it from the metal substrate by corroding the irregularly in certain points more uncertain less making small craters things like that then another thing if you want you can brush it let's see how it comes with a brush to become it now let's see for a moment this happens that the microporosity produced by Reggio was the final practically the poles what happens as mountains with delpo valleys zzi in the middle, however, mountainous coasts it happens that these go to flatten and bend these mountains listen to them where they come off being able to therefore a bit of polish unfortunately it is a piece that has been very corroded but you see how nice at this point at this point we ended up torn demonstrative by treating eaten points one way certain to the other the typical have brushed which we had reduced the iron which are black dots now no longer rusty then comes I'm still gathered at this point beautiful girl dancing boys
