Nothing. I've tried works as well for me as MF madness wash media for rinseless. I have the new rinseless wash mitt described in this thread and it's better than using MF towels, but can't compare imo to MF madness wash media. I don't even use MF towels anymore for rinseless. I use one MF madness sponge to wash and one damp MF madness pad for final wipe. The great thing about the MF madness sponge is that it holds way more solution as a MF towel so when you wipe it's releasing solution at such a high volume that it's literally washing contaminants away from the wash media like as if you were flooding the area with a hose at low pressure. This is huge because the media stays clean thereby not requiring anything more than a bucket and grit guard. I've washed dozens of cars before needing to clean the sponge in the washer. Hope AG sells them at some point.
