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 Kelly Kaliyan

Received my 25 piece set yesterday. We recently renovated our home and added a mother in law. It has a separate entrance, a large studio room with a kitchen and a small bathroom. The bathroom was a problem area. The contractor used a storage tub that was not well protected and got dirty before it was even used. It had a horrible ringing sound even before anyone took a shower. I've tried everything you can think of to delete it to no avail and I was disappointed. Brand new bathtub that looked dirty. The first thing that struck me was the lack of an instruction manual. I had to use the color guide website to figure out which one to start with. I started with a yellow brush using the Soft Scrub. I had a hard time controlling the brush so figured it was a learning curve. I then used a green scrubber with a soft scrub. It was easier to control, but there was no result. Some of the scale is gone, but not much. I then rinsed the tub and sprayed Rejuvenate Soap Scum Remover on it and continued with the green pad. A little more has been removed, but still unsatisfactory. In the middle of the work I decided to use a yellow and black round brush. It was VERY easy to control, but there was still foam. Flushed the bath and took a break. I went back and tried the Green Wheel Brush, Yellow Black Wheel Brush and Bar Keepers Friend (BKF) Mild Cleanser. I finally started seeing some results. About 80% of the soapy water is removed after about 2 1/2 hours of operation. I'll look into this again tomorrow and post an update.
