So I tried dunk test in middle with ONR bucket. Sponge was dipped. Swirled around but touched no grit guard or side.
I believe this is V4. This was mid wash bucket I used.
Both sides of dirty sponge: After dunk:
Sponge completely clean which I understand is not expected In polymer rinseless.
I never got on the sponge bandwagon (until now where I bought all the cool sponges to see what the excitement is...haven't gotten to use any yet), so I can't really speak to the sponge staining (I did buy the Optimum blue waffle sponge a long time ago and I don't remember it staining and I looked at it a few weeks ago and it looked fine, I would have cleaned it well before putting it away though).
However, my favorite rinseless wash media is the long-defunct Meguiar's microfiber Quick Detail Sponge, this is like "the bone" but it has a much softer sponge in it. It was sold in 2004 along with the Meg's brushes; all of them were discontinued at the end of that year and I picked up a lot of the sponges at Big Lots (does that still exist?).
So these sponges (the Meg's and "the bone") are supposed to use a different kind of microfiber that doesn't hold on to dirt in the way a towel would, this is the description from MicroFiberTech: "The non-split micro fibers of this jumbo car sponge, unlike most microfiber cleaning products, easily release the collected debris when rinsed with a hose."
Anyway, my point is, I don't know about the sponges, but when I use these "bone" media with RW on a dirty car, they are black/gray after the first panel, and after that, you can't tell what's coming off the subsequent panels. Laundering doesn't help, the only thing that does is pre-treating/soaking with OPC (which was the OPT recommendation). I have tried to use the washing machine "pre-wash" using OPC, but that was not entirely successful the one time I tried it...experimentation ongoing.
So I think choice of wash media may have a lot to do with why some of us complain about media staining and others don't know what we're talking about. FWIW Idrosave was the worst for me, worse than ONR.
