I was in dire need of cleaning out my new foam pad after one use, as I could already see that after doing half the car, the finish from the first panel to one o was doing was not the same.

Came across this which I intend adopting from now on, however I would love to hear from fellow fanatics what successful methods they've adopted in cleaning foam pads.
