Pour the hot water into the bucket. The bucket needs to be large enough to hold all of the fabric and solution.
Measure and add both the alum and the borax to the hot water. Stir gently with the stir stick until the alum and borax are dissolved.
Immerse the fabric in the bucket of fire-resistant solution. Push the fabric gently under the water until it is completely soaked. Let the fabric soak overnight.
Put the rubber gloves on your hands because the solution can cause skin irritation. Wring the solution out of the fabric.
Place the fabric in the dryer and run it on the cool setting until the fabric is completely dry.
