Prior to my introduction to Meguiar's Non-Acid W&T cleaner I was a BIG supporter of the Eagle One A-Z!!! GREAT PRODUCT if anyone ever runs out of wheel cleaner between cars! Go get some you wont be sad.
i have a silver A2Z head from the early 2000s that i still use to this day on one of my bottles for full strength Power Clean. i remember that stuff worked very well but it was hella expensive vs. APC lol.
