..I'd like to take Accumulator's recommendation on the Griot's rubber cleaner. Some of the APC's I've tried seem to react in the same way as the Hi-Temp stuff..

I've been using griots rubber cleaner for over 5 years and it works great believe it or not. I don't clean the tires every wash but when I do spray it on all this brown and black garbage comes off with ease and that's with me being too lazy to agitate with a brush...
Yeah, the Griot's continues to work well for me. I do scrub the tires (gotta be careful on the S8's *SOFT* tires, can't use a plastic-bristle "tire brush"

), but I'm also using the Griot's Rubber Cleaner diluted most of the time so it needs a little extra help as it's quite mild to begin with.
When rubber items are really soiled, I'd sure use it undiluted and I'd also a) let it dwell and b) plan on multiple tries. Too mild? Probably for some people.
I've toyed with the idea of trying something less expensive, but I worry that it'll behave the way the other stuff
Setec Astronomy uses does. I tried some generic stuff from the local autobody/paint supply store, and I did *NOT* like how it worked on the Yukon's Goodyears (tires with a "stays black" additive that I don't dress for various reasons). It left them a little brown and dried-out looking, just not the crisp, black "new rubber" look I get with the Griot's Rubber Cleaner.
Similarly, I don't like the idea of using citrus degreasers (even TAW) on rubber as I don't want to "clean off" something a little too well and end up drying out the rubber. I have *zero* idea whether that fear is truly justified but I'm not gonna find out on *my* tires
I've done OK using diluted Griot's/P21s wheel cleaner on tires, but I just think the Rubber Cleaner works better. I like to think the Rubber Cleaner is specifically formulated in a way that makes it better for this and I note that there's a caveat against allowing it to contact auto glass (
Setec- recall our discussion of how today's autoglass isn't "just glass" but has plastic/whatever mixed in).
Griot's Rubber Prep product works great too, really super on tires that have odd issues (adhesives, etc.) and it even brought back some *hideously* oxidized rubber trim on an old Audi...simply amazed me how well it worked and it was the perfect prep for my Ultima Trim Sealant (or whatever the proper name is...). No way to exaggerate how well that combo worked and the items in question sure looked beyond salvaging.
