CITRIC ACID

Use Citric Acid in place of vinegar with your acid dyes.  You won't get the smell that comes with vinegar, but you still get the acid needed to make the WashFast Acid dyes work properly.  You need just a little.  Sprinkle it like salt into the dye bath.

Citric Acid is packaged in 200 gram portions (7.06 ounces).
