Here are 6 unexpected and practical ways to use WD-40 around the home. While the image shows spraying it into a car’s exhaust, that’s not a recommended or beneficial use.
1. Remove Sticky Residue
WD-40 can help dissolve glue left behind by stickers, labels, and tape on glass, metal, and many hard surfaces.
- Spray a small amount.
- Let it sit for 1–2 minutes.
- Wipe clean with a cloth.
2. Silence Squeaky Hinges
A quick spray on door hinges, gates, or cabinet hinges can reduce squeaking.
- Wipe away excess to avoid attracting dust.
3. Loosen Rusted Nuts and Bolts
One of WD-40’s best-known uses is penetrating rust.
- Spray generously.
- Wait 10–15 minutes.
- Try loosening the fastener with a wrench.
4. Clean Stainless Steel
WD-40 can remove fingerprints, smudges, and water spots from stainless steel appliances.
- Spray onto a cloth (not directly onto the appliance).
- Wipe in the direction of the grain.
- Buff with a clean cloth.
5. Remove Scuff Marks
It can help lift black scuff marks from tile, vinyl flooring, and some painted surfaces.
- Test on a hidden area first.
- Wipe thoroughly afterward to remove any oily residue.
6. Protect Garden Tools
After cleaning shovels, pruners, or shears, a light coat of WD-40 helps prevent rust during storage.
- Wipe off any excess before using the tools again.
Important Safety Tips
- ⚠️ WD-40 is flammable, so keep it away from flames, sparks, and hot surfaces.
- 🚫 Do not use it as a lubricant for bicycle chains, door locks, or items requiring long-lasting lubrication—specialized lubricants work better.
- 🚫 Avoid spraying it on brake components, tires, or electronics unless the product is specifically designed for those applications.
- 🚗 Spraying WD-40 into a car’s exhaust pipe, as shown in the image, is not recommended. It won’t improve engine performance or clean the exhaust system and could create unnecessary fire or smoke hazards if misused.
Used correctly, WD-40 is a versatile maintenance product, but it’s best to stick to its intended applications rather than viral internet “hacks.”
