Big dilemma, need advice please
I bought some beautiful batik fabric at the quilt expo recently and the instructions say to pre wash in warm water before using to remove any excess wax and dye using synthrapol. The instructions on the synthrapol bottle says to use very hot water, hence my dilemma. If I use very hot water will it damage the beautiful fabric, if I use warm water, will the synthrapol not work. Any advice will be welcomed.
