Aerosol spray silicone should be avoided because (1) common aerosol propellants may attack plastic
and rubber parts, and (2) because only a slight amount of silicone remains after the solvent evapo-
rates, and provides no lasting benefit.
DO NOT use muriatic acid for the cleaning of any parts. Muriatic acid, even when strongly diluted, can
harm chrome plating, and may leave a residue that is harmful to O-ring seals and other parts.
Silicone rubber requires no lubrication or preservative treatment. DO NOT apply silicone grease or
spray to silicone rubber parts. Doing so will cause a chemical breakdown and premature deteriora-
tion of the material.
