Are there any patents to worry about building a tire washer to sell. I think I have the most economic idea. I'm building one now I'll report on how the build goes. The first one I build I'm just going to buy a pressure washer broom fix it in box and have a hub in the center I'll get an electric pressure washer from harbor freight. That's the basic outline. I will have a heated reservoir gravity feeding the pressure washer. Any ideas chime in I'll take all input. I'll post pics when I'm done. I'll be building these in the future and will help anyone I can. Tire washing is important and time consuming my goal is to make it easier for everyone to wash tires.
