Ive been using Extra Tough Tire and Wheel cleaner for about a year now. Yes, same Extra Tough as the APC. I spray it on with a pump sprayer, let it dwell for a few minutes and then remove with a microfiber towel. Pulls a lot of junk off the tires and wheels and leaves a matte finish on the tires that will last a week or two in dry weather with driving every other day. No nasty, harsh in your face smell. As this is part of a twice a week rinseless wash process, the longevity of the finish is no concern for me. Biodegradable and designed as a waterless product (per an email from the company), I have not found anything else that requires no water and works as well.
