Hi Devin,
How have you been, man? I was in my kitchen the other day and ran across the business card you gave me at Evansville.
One thing I recommend changing from the above posted directionsL
Agitating the pad by hand before placing in water, and then agitating again by hand once placed in water.
After I spray my pads with Dawn, or APC+, I don't wait to put them in water and then agitate them. Here's what I do and I've even been able to thoroughly remove Duragloss 501/601 from my pads.
I go to my sink and I apply Dawn concentrated dishwashing liquid to each pad I clean and then spread it around thoroughly...a liberal amount. As you spread it around it soaks into the pad, just like when priming a pad. I then wet the pad a bit and begin aggressively working my fingers and thumbs into the pad for a couple minutes each, then rinse. Seldom do I have to do this more than once and they come out real nice and clean.
On occassion I'll need to clean a pad twice. If I need to do this a second time I'll spray a little APC+ on the face of the pad, add some dishwashing liquid and start working it in, then rinse.
This total procedure has worked flawlessly for me and can turn white polishing pads back to their original new state of white. Some of the used polishing pads at Evansville that I got were cleaned and made as good as new.
You should be able to replicate a similar procedure using your chemical guys product. If it doesn't clean like you think it should, add a little more spray and then add some dishwashing liquid, work it in, then rinse with luke warm water.
I've also worked my products in by hand on each pad, and thrown my Meg's pads in the washer. They always come out looking like new. Zero issues with backing coming off. Lake Country pads have had a few backing issues, but they too come clean. I can fix the backings if I have to.
