The IPC Eagle Cleantime 36 ride on scrubber needs two of these 18" tynex scrub brushes. They are an aggressive nylon brass mix brush for general scrubbing or stripping finishes from cement only. Use with our Easy Lift concentrated floor stripper for removing those really tough floor waxes. All tynex brushes must be run in a wet environment.
