you can reuse BJS but not the rinse, you add it to water. how much it takes per sheet depends on how absorbent your fabric is, you just pour plenty in the pan so it is totally covered, you sure don't want a dry spot.After it has soaked , I think it's 5 mins. lift it up and let it drip a bit then hang it to dry. I don't lay mine on a towel because it seems like it would suck the BJS out of the fabric, I may be wrong and that would be a first! :shock: After it's dry press it but be careful because it will scourch more easily.
