Kwik-Clean flux remover doesn't need mixing or diluting. Just spray on Kwik-Clean when you're done soldering, then use paper towel to clean project thoroughly. ALSO USE WITH PATINA: use either the same paper towel or a clean one to apply the patina. Mixing the Kwik-Clean with Patina gives added cleaning of the flux and a finer tone on the patina. After Patina is applied, clean again with Kwik-Clean. Polish as you normally would. 16 oz. with sprayer.
