Adding a bit of dishwashing detergent to the borax remjet bath makes the process much, much less messy. The detergent prevents the remjet from redepositing from the wash water back on to the film, sponge, hands and everything else. I found putting the film in a bucket with the borax & detergent for 10 minutes and giving it a swirl removed the backing cleanly with no muss, fuss or wiping.
