Pad wash recommendations

I was looking for ideas for polishing pad cleaners. Chemical Guys and others do bespoke products with matching brushes which look good but then I saw Jon (?) on Forensic Detailing demonstrating cleaning pads with APC and a toothbrush. Seemed pretty effective.

Anyone else use that method and if so what's your APC of choice ?

Thanks

 

Stick it to a velcro strip and blast it with a jet wash.

Fairy liquid plus warm water ....it will remove even Autsol from the pads....
