I'm using the rotary floor scrubbing mats that they describe. There are
a few online cleaning suppliers that sell them. I cut them up into 1"
squares with scissors, it's tough going. Probably best to try and get
hold of an electric tool that can do it faster, perhaps a rotary saw or
reciprocating blade.

Not sure if it will work on scrubbers, but electric kitchen knives (for
carving turkey and such) does a great job on poly fiber matting.
