Both of the sites noted above carry 'Adams Wheel Cleaner'. This does not appear to be the same product as the 'Adams DEEP Wheel Cleaner' I bought about 4 years ago after a demonstration of it's performance at by a DC area detail shop.
A P-928 meet was being held at the detail shop, and the owner demonstrated quite a few of the products he used. Everyone was amazed at the results with the DEEP Wheel Cleaner. Can't say the current product WON'T work as well, but it certainly isn't labeled the same, nor the same color in the spray bottle.
