You will not believe this because I don’t believe it myself. I used this product yesterday to clean the wheels on my 2010 MDX. Followed instructions to the tee. The wheels are clean but they have a completely different look. Originally they were bright glossy silver but now they are less glossy and look more gray than silver. I have poured over many product reviews from both UK and USA and no one mentions this. This product is supposed to be pH balanced and totally safe for all wheels. I am going to contact Meguiars but thought I would ask here just in case someone has had a similar experience. Obviously Meguiars is not going to buy me new wheels, heck I would not even ask for that on a 10 yo car. Maybe they will test the product to make sure it is good.
