These everyday scrub brushes are meant to be used with our Mastercraft compact walk behind electric scrubber. They will not harm any hard surface, and can be used daily. For an outline on how to scrub, please take a look at our auto scrubbing procedures. This will help you decide on what caution devices you should put in place, as well as what type of chemicals to use.
*Note: These brushes are sold individually, but you will need 2 to properly run your Mastercraft auto scrubber.
