I was so tired of scrubbing my toilets till my hands were raw and so saw this and decided to try it. This Drill brush set by #Glotoch works like a dream. It really did all the work for me. I put some clorox inside of the toilet let it sit for about 30 minutes. Then I put some Scrubbing powder in and let that sit for 10 - 15 minutes. Put the heavy duty brush onto my drill like a drill bit and turned it on. It literally took years of grime right off the toilet making it sparkle and look brand new. I then used a flat brush head to clean the shower enclosure and it too took literally minutes to get it sparkling like new. I highly recommend this set for anyone looking to restore their bathroom back to it's brand new condition at a fraction of the cost. At $8.98 for the complete set of 3 heads you have nothing to lose and lots to gain!
