Re: {Collins} noisy pots



WD-40 ??? That's the worst stuff to use, right next to TV Contact
Cleaner.

I suggest you look into De-Oxit.

>The long term active ingredient is a non-volatile, viscous oil which remains on the surface, providing lubrication and protection from moisture. This is diluted with a volatile hydrocarbon to give a low viscosity fluid which can be sprayed and thus get into crevices. The volatile hydrocarbon then evaporates, leaving the oil behind. A propellant (originally a low-molecular weight hydrocarbon, now carbon dioxide) provides gas pressure in the can to force the liquid through the spray nozzle, then itself diffuses away.

>WD-40's formula is a trade secret. The product is not patented in order to avoid completely disclosing its ingredients. WD-40's main ingredients, according to U.S. Material Safety Data Sheet information, are:

>    * 25%: Liquefied petroleum gas (presumably as a propellant; carbon dioxide is now used instead to reduce WD-40's considerable flammability)
>    * 15+%: Mineral oil (light lubricating oil)

>    * 60-80%: Heavy Naphtha (petroleum product), hydrogen treated
>    * 1-5%: Carbon dioxide

>It further lists flammability and effects to the human skin when repeatedly exposed to WD-40 as risks when using WD-40. Nitrile rubber gloves and safety glasses should be used. Water is unsuitable for extinguishing burning WD-40.
