It's in everyone's toolbox. It's the go to product for taking squeaks away, displacing moisture, and preventing rust. There's a lot of things you can do with WD40. But while it has tons of uses, it not the cure-all product thought out to be. In fact, there are some jobs where WD40 shouldn't be considered for.
Here's a guide to when to use the lubricant around the house:
Use WD-40 To:
1. Spray WD-40 on a shovel, spading fork, hoe or garden trowel to get soil to slide right off.
2. Clean tiles - it will remove mascara, nail polish, paint, and scuff marks.
3. Scrub stains from stainless steel sinks.
4. Unstick gum. Very useful.
5. Soften leather.
6. Erase crayon. Spray on and wipe off. Wax on, wax off.
7. Prevent flowerpots from sticking when stacked together.
8. Get rid of rust.
9. Remove goo from price tags, duct tape, and stickers.
10. Silence squeaks but.. (see below)
Don't use WD40 on:
1. Door hinges because that attracts dust and dirt.
2. Bike chains. Contrary to popular belief that it will smooth your ride, WD-40 can cause dirt and dust to stick to a chain. Use specific bike chain lubricants instead.
3. Paintball guns
4. Locks. The spray can prematurely wear down the internal mechanisms.
