Yeah you can use acid on chrome (spray on leave for a few minutes then hose off throughly) though if you thoroughly clean and seal the wheels the use for acid is not required just car soap and water also when using acid be sure to wear to loves and eye wear
Meguiars D140 white brightner is a good acid cleaner though if you want something OTC Eagle one etching mag wheel cleaner is great alternative also if you want to agitate the acid cleaner you can it you want just don't use one of your pride brushes
