2. Clean tile. The spray removes spilled mascara, nail polish, paint and scuff marks from tile floors, and also help you wipe away grime from the grout lines. Clean up with soapy water.

3. Scrub stains from stainless steel sinks.

4. Unstick gum. A squirt makes it easier to pull gum out of carpet and even hair. It's better than cutting out the gum and leaving patchy carpet or a bad haircut.

2. Bike chains. WD-40 can cause dirt and dust to stick to a chain. Use bike-specific lubricants, which typically contain Teflon.

3. Paintball guns. WD-40 can melt the seals in the guns.

4. Locks. The spray can prematurely wear down the internal mechanisms, especially in the pin tumbler locks, in door locks and padlocks. Go for graphite powder.

5. iPods and iPads. WD-40 won't repair the Home button on these devices. In fact, the spray can cause the plastic to break down on the cover, and if some gets inside the electronics, it can damage plastic parts inside.
