I have the L/C Pad Washer. It will work great on all but the Hydro-Tech pads, which it will help Shred, more than they already do with use. This machine works best with a Rotary.
You put an envelope of Snappy Clean in the bucket, fill it with water half way,, and you are set for a week or two.
Recently, believe it was Todd talked about using Meguiars Super Degreaser on pads, and I tried it. By hand, this cleans pads quickly, and rinses out way faster than any other soap I have ever used.
One caveat - you need to be careful how strong your mix is or it can remove the microfiber backing off the foam pad.
Do a search on this and find out what mixture he was using, etc...
I have a VX5000 but have never thought of steaming the pads; would worry what 298 deg could do to the microfiber backing, anyone have experience here ?
