We had the opportunity to check out this Spin-Scrub Drill Brush Heavy-Duty Bathroom Scrubber Accessory Kit by HOME BODY and is is super awesome. We used it to clean the tub and it did wonders to make it white again. So much less elbow grease. Very easy to attach to drill. Comes with a total of 6 scrub pads, they can be cleansed and reused also. 7 piece kit includes velcro base pad with hex shaft bit and 6 heavy-duty nylon pad.
