Overview
The transcript provides 15 car maintenance and repair tricks using WD40, highlighting professional tips, essential warnings, and cost-saving applications, along with critical mistakes to avoid.
Rust Prevention and Repair
- Regularly spray WD40 on exposed car metals to create a moisture barrier and prevent rust and corrosion.
- Clean and coat chrome, hinges, latches, and wheel wells for easier future cleaning and long-term protection.
Diagnostic and Maintenance Tricks
- Spray WD40 near vacuum hoses while engine runs; a change in idle identifies vacuum leaks for quick diagnostics.
- Use WD40 on license plates after cleaning to restore clarity and avoid fines for unreadable plates.
Tire and Rubber Care
- Apply WD40 to clean, dry tire sidewalls (never treads) to restore shine and protect against UV damage.
- Use WD40 Specialist Silicone Spray on weather stripping to maintain flexibility and prevent water leaks.
Electrical and Engine Applications
- Spray WD40 on electrical connectors (with power off) to repel moisture and prevent corrosion.
- WD40 Specialist Contact Cleaner is preferred for delicate electronic components.
- Use WD40 to displace moisture from ignition components after exposure to water to restore engine function.
Paint and Surface Protection
- Remove tree sap from paint by spraying WD40, letting it sit, and wiping gently, then wash and wax.
- Avoid using WD40 as a scratch remover; it only masks scratches and attracts damaging dirt.
Lubrication and Stuck Components
- Apply WD40 Specialist Penetrant to free rusted bolts and nuts, working quickly for best results.
- Restore chrome surfaces by cleaning with WD40 to achieve shine and add a protective layer.
Battery and Electrical System Protection
- Clean battery terminals and coat them with WD40 to prevent corrosion and extend battery life.
Critical Safety Warnings
- Never use WD40 on brake components; it reduces friction and can cause brake failure—use proper brake cleaner instead.
- Do not add WD40 into engine oil or fuel; it is not a lubricant and can cause severe engine damage.
Wiper and Door Maintenance
- Clean and lightly treat wiper blades with WD40 Specialist Silicone Spray to prevent squeaking and extend blade/windshield life.
- Lubricate door hinges with WD40, then wipe excess to prevent sagging and sticking doors.
Decisions
- Do not use WD40 as a scratch remover or as an engine additive.
- Always use silicone-based WD40 for rubber and weather stripping.
- Never spray WD40 on brakes; use designated brake cleaner.
