Sodium Metasilicate was the main active ingredient in Westley's Bleche-Wite from years past. Same chemical was used in many other WW cleaners. It was what caused the hard to breathe sensation when you sprayed it on a tire. This chemical IS NOT the same as Sodium Silicate. Sodium Silicate is used as a skin tightener in cosmetics. Sodium Metasilicate would cause skin burns when applied to the skin. Good thing pistons are more sturdy than skin.
