Review on Holikme 30-Piece Drill Brush Attachments Set with Scrub Pads Sponge - Power Scrubber Brush for Grout, Tiles, Sinks, Bathtub, Bathroom, Kitchen, Automobile - Long Extendable Attachment for All-purpose Cleaning by Kimberly Peterson

This is a revolutionary product for deep cleaning my tub and tiles! Back doesn't hurt anymore! It's east too! I used a brush extension. Just use it without the extension attached to the drill chuck. The little brush was great for corners. The big yellow-green brush picked up all the suds and dirt! I bought a pack with all the brushes in different sizes, pads and sponges. From soft bristles to hard bristles. The bottom of the tub has a textured pebble surface. So you don't slip. Well, it builds up with soapy water. I would have to spray on the cleaner, use the brush and really scrub by hand. As a result, my shoulders hurt and I was pulled back. This is salvation! Both the bathtub and the tiles shine! It was easy as the cordless drill does all the work! I'm sure a hard black brush would be great for grilling!
