I purchased a 17oz. bottle of power clean. I primarily use it to clean tires and wheel wells. I use it straight non diluted. Should I dilute it? It concerns me that it may cause damage to my nice wheels if it lands on them. or sits on the wheel lips when I use it to clean my tires. I have seen videos where people use it to pre treat heavily dirty painted areas or on bumper with bugs. I wanted to get Adams tire cleaner but opted for pic since I could use it on wheel wells too.
