WD40 Is Your Friend

WD40 is your friend.
WD-40 isn't actually a true lubricant. WD stands for "water displacing" and its main use is as a solvent or rust dissolver. The lubricant-like properties of WD-40 come not from the substance itself, but from dissolving components. ... WD-40 can be a good substance to start with — it can help clean up rust or other grime.

We use it for just everything here, at the auction house.
1.Use it to get rid of rust
2.Use it to clean plastic.
3.Use it instead of oil on mechanism of old toys, unlike oil it evaporates
4.Use it on Naugahyde- makes it look like new.
5. Use it to remove nicotine on oil paintings( this takes A LOT of PRACTICE- quickly, and with a light hand) better than potatoes, and bread to clean oil painting .
