For month I made my goat milk soap with never a problem with ash. I was covering the top of the mold with saran wrap and letting it gel. No ash but dark soap so I stopped gelling and now I am getting soda ash even when I cover with saran. I switched to generously spritzing with 91% alcohol and still have ash worse than ever. Anyone know what is going on and also since I sell my soap how can I remove the existing soda ash.
