    Calcium, Rust & Lime Remover

    Posted by K on 30th Jul 2018

    This stuff is amazing and not like any of my other lime cleaners. This was recommended to me several years ago by my plumber. A little goes a long way, I'm only ordering my 2nd bottle now. I initially used on old problem areas, now I use weekly on two (modern, open style) faucets and in other areas sporadically to maintain. If the buildup has been there a long time you may find that this (miraculously & instantly!!) removes it but that the finish underneath is damaged. I had some brass trim around a shower, it instantly dissolved hard white thick crust but underneath finish is now black from years covered in lime. Regulag maintenance to manage early rather than heavy duty old stains will avoid this. But that said, I still much prefer the discolored finish to the crusty lime! This is a great product the professional's use, a bottle should last you a long time.

    Works as Advertised

    Used the product on the steel fittings of my boat. It worked quickly, but required more than one application. The need to wash it off immediately was only slightly inconvenient. Completely satisfied with the results.

    Thank you for saving me from the expensive route of window replacement

    Posted by SSgt Nicholas S. Phillips - Los Angeles, CA on 14th Feb 2013

    I have had hard water and lime stains on my 97 Honda Civic windows for over 5 years. Finally I have been able to remove them. I was skeptical to say the least. But figured I would try this economical attempt at removing the stains before taking the drastic measure of replacing the windows with new ones. The stains came from 2 years of sprinklers with recycled water pelting the passenger side of my car while it was parked in my driveway. Furthermore I was stationed at Edwards AFB and the extreme heat of the Mojave desert summers had baked on the stains. I honestly felt after two trips to auto detailers and using home products(Lime Away and CLR to name two) that there was only the expensive route of window replacement to get the clear windows I strived for. But thanks to your product and simple instructions you have saved this overworked and underpaid Air Force Staff Sergeant from dipping into my savings account.

    I can't thank you enough

    My late father, 2nd Lt. Maurice J. Wasser, was a POW in Germany. Following his passing, I found my father's POW Dog Tags, rusted with oxidation. Nobody would attempt to clean the tags, since we didn't know what they were made from. I sent an e-mail to the USAF, who told me how to figure out if they were ferrous or non-ferrous. After determining they were ferrous, I purchased your product this afternoon and began the task of cleaning these most precious tags. They are BEAUTIFUL! I probably still have a little bit of polishing to do, but what a difference. These tags were special because my Dad's POW number was 147023 and my birthday is 012347! My sister made them into a necklace for me but the rust was awful and would stain my clothes. THANK YOU FOREVER for restoring this for me!
