I think you mean Dawn Power Dissolver. It works great for pads that just won't come clean. When first washing pads, I do similar to what someone mentioned above. Fill a bucket with hot water and then use either Dawn or APC (haven't decided which I like better). I will massage the pads quite a bit and that will get most of the junk out of the pads and then ring the solution out of the pads. Then I dump the dirty solution into the toilet, rinse the bucket a little then fill up with hot water with Dawn or APC again and this time let them soak for atleast a half hour. I then massage the pads again and generally this will finish the job and I can then rinse the pads and spin them on a rotary and dry them in the sun or in front of a blower I use to dry carpets after shampooing and rinsing them.
In the few cases where the pads still need cleaning after the half hour soak job, I then reach for the Power Dissolver. That is some powerful stuff, you may want to wear gloves, it can really dry your hands out. After the pads have soaked in the bucket of Dawn or APC solution and I have ringed them out and I see they need need Power Dissolver, I will spray the Power Dissolver on the pads and work it in with my fingers and let it set for about twenty minutes. After the twenty minutes, I will rinse the Power Dissolver out of the pads with warm water in the sink. No matter how much I rinse my pads I can never get the strong smell of Power Dissolver out of my pads so I will make up a warm bucket of water with Dawn or APC and wash the pads one more time which will get the smell out.
Alot of work but it will get any pads clean.
