I picked up a spray bottle (32 fl oz) of LA'S TOTALLY AWESOME OXYGEN ORANGE all purpose degreaser and spot remover at the Dollar Tree store for a buck. It did a better job of cleaning my pads then any other product that I have tried. I just generously sprayed it on and worked it in after let it stand for a few minutes, and just rinsed them out. I got a brand new clean pad results. Went back and picked up a few more bottles. This is the Orange bottle, cause they sell other degreaser's products.
