Review on Liquid X Original Wheel Woolies Brushes 3 Piece Kit - Angled Caliper Spoke Brush - USA Made - Black - New & Improved: Ultimate Wheel Cleaning Toolset by Antonio Urbina

The large brush cleans most of the inside of the wheel and holds a ton of soap, however small brushes are not very effective. It's best to use a small microfiber cloth the size of a washcloth and a couple of brushes to get into the crevices. Smaller brushes need to be fluffier to get into crevices and have some material on the ends to poke or get into stains for cleaning. The only benefit of one of the smaller ones, the curved one, is the ability to get past the spokes and reach areas you can't reach with a big brush. In general, I still have a hard time cleaning the wheels, which I suspect are regularly shaped, and have used a variety of "other" brushes to get the job done. Brake calipers for example won't get clean with these brushes but you can start with medium or small brushes to get the main areas and then use some wool brushes for the corners etc. These brushes are a one stop shop. I wish the smaller ones were fluffier and had a pom pom at the end to get into corners. I would also like to see a process where I could remove the brush heads and throw them in the wash. I worry about getting a lot of dirt on the brushes and the more I use them the more I can scratch the wheels. I clean them by soaking them well in water and swirling them to fling the dirt out, but I'm not sure this is effective due to the color and material of the brush, so fine abrasives can get stuck there, which I can't see. A little bit nervous.
