ive searched and i ant find out how to clean it...if someone could please assist me on how to ..i have a turbo XS blow off valve for a 2002 wrx....thankyou

if no knows, the you might want to direct your question to turbo XS.. they should know what chemicals are good/bad for it.

if you are talking about an RFL, you just need to unscrew the top and pull out the spring and piston. then clean away.
