In this post, we are taking a look at P&S Brake Buster. This is an extremely popular all in one wheel and tire cleaner that is not only suppose to safely remove accumulated brake dust and other contaminants, but this product also contains corrosion inhibitors which will leave a layer of coating behind, protecting the wheels from future corrosion. Brake Buster is non-acidic and should be safe on most wheel finishes but remember to always test new products out on an inconspicuous location before going all out.

For my initial testing, I cleaned the wheels and tires of my Supra. For this, I diluted Brake Buster at 5 parts water to one part product and use the solution in an IK Foam Pro 2. From my research, this seems to be the go-to combination for many people but Brake Buster can very well be used at full strength or even further diluted. You’ll just have to experiment with the product to see what works for you.

For my personal use, I spray Brake Buster onto the tires and wheels and let it sit for a moment. This will allow the product to loosen and break down some of the contaminants. Because Brake Buster is nonacidic, it will only be able to remove so much by itself. For the most part, we will need to go in and do a contact wash. I personally like to have a bucket with some car shampoo in it to help with lubricity but I know a lot of people who only use Brake Buster for the entire cleaning process. If you want to do this, just make sure to spray some more Brake Buster to get added lubrication if you’ve let it sit for a while and most of it has slid off.

For the most part, Brake Buster did a great good at cleaning these wheels. Aside from the places that I missed and the water spots that were already there, the wheels were clean.

Next, I moved on to the wheel of a Corrolla that’s a daily driver and I can’t even remember the last time it was cleaned. For this, I used Brake Buster at full strength in a spray bottle. Because this wheel is pretty dirty and I’m not diluting, the chemical reacted immediately with the wheel and tire upon contact. Brake Buster did its thing and removed some of the grime without any contact. This was evident by a brown runoff. But, again, unless you only have a light layer of dust buildup, a contact wash is still needed. Again, Brake Buster did a great job at cleaning the wheel.

After trying Brake Buster for myself, I can see why it’s pretty hyped. At around $20-$25 a gallon, Brake Buster offers a versatile product that adequately cleans anything in the wheel wells. The ability to heavily dilute this product down to 10:1 and even beyond depending on your needs further adds to the value of this product. Then on top of this, Brake Buster also leaves behind a layer of corrosion inhibitors, something that very few other wheel cleaners do. So for me, Brake Buster gets a recommendation because it does what it’s supposed to at a great price.
