Measure 1 gallon (4 liter) of 120oF (50oC) water into a 2 gallon bucket. Add 4 level Tbl (60 g) of Alum (Aluminum Sulfate) and stir until dissolved. While wearing rubber gloves, add the washed fabric (wet or dry) to the Alum Soak. Soak it for 15 to 20 minutes with intermittent stirring. Make sure the fabric is completely submerged and can move freely.
