You cannot dilute this product to use.i have 33x12.5 mud tires with a lot of brake dust on my tires by my standard. I used a mix of 50/50 then 75/25 then full strength i still had brake dust yes the brown rusty color was still on them and i used a bristle brush. Putting on tire shine masked the rest of it. 4 tires uses a lot of this product. Not much of a deal to me
