Wheel cleaner questions are among the most common Meguiar’s reps are asked. “The safest product to use is obviously a regular car wash soap. It is a very mild product that will not damage a wheel’s finish,” Pennington says. If you need more cleaning power than that, try a dedicated wheel cleaner. Here are Meguiar’s wheel cleaners arranged left to right in order of acidity. Bare aluminum wheels stain and corrode very easily. Be sure to use the mildest cleaner you can buy, like the Hot Rims aluminum cleaner on the left. Pennington says it is Meguiar’s most gentle wheel cleaner. Chrome cleaner is the most caustic and should only be used on hard, chrome-plated surfaces. All other wheels can use the product in the middle.
