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 Michelle Wilson

I have very hard water and have just upgraded to a water softener and filtration system. I've tried many different cleaning soaps, brushes, putty and it could make a dent but not everything was clean and clear. Today I used liquid bartenders with a black brush and it worked! There were still faint marks of hard water, so I went over it a second time with a green mop. I'm so glad I'm finally rid of glass and metal! I never thought I would use power tools for cleaning, but I'm very glad I tried! It took less than half the time and a minimum of physical effort to make everything shiny and clear. I will definitely buy these again!
