I still use the brushes with the handles. I use envirowash ink remover and the same for stencil remover. As far as the degreaser and stain remover, I use pink stuff. I've been doing this for about 4 years now and I haven't had any problems. I'm only one that ever reclaims so I haven't had one pop on me in about 4 months now and it was a a roller frame that mysteriously split in the rack but I think that had to do with me pushing the limits with the stretching.
As far as how, I remove the tape and brush the ink remover in on both sides then pressure wash them on both sides. Then to the dip tank. I pressure wash the stencil out and then immediately brush in the degreaser on both sides kind of aggressively followed by a good pressure washing on both sides. I then flood rinse from top to bottom with the hand nozzle before it hits the rack.
