Summit Brands OUT-AO06N-1/PACK Heavy-Duty Rust, Lime & Calcium Stain Remover, Multi Purpose Cleaner, 24 Ounce, 1 Pack, White, 24 Fl Oz

Had limescale build up in toilet bowl and tried many different products over the years. Put lime out in the bowl followed by scrubbing with hard brush, rinse then repeated a few times. Could not believe it removed all the hard limescale in less than 15 mins and toilet looks like new.

This stuff is amazing. Wish I'd have taken before and after pics but didn't think it would be this good! We had the most awful, thick, rock hard limescale in our toilet. No matter how hard I tried or what I used nothing worked. We were looking at buying another loo, till I came across this product and had one last attempt to clean it..... Holy shoot did it work. Poured some in over night, the next morning it was almost gone, so did it the next night too and pow! All gone, literally like new!!!! I am so shocked and amazed at this stuff that I have to shout it from the roof tops, buy it, you'll be happy you did!!!!! xXx

Fantastic product - gets rid of stubborn limescale marks way better than supermarket alternatives. My only gripe is the price - this is twice the price it should be!

lo utilice en un cristal, con manchas de agua algo antiguas y no se quitaron, por el contrario MANCHO EL PISO DE MI REGADERA ( de cerámica) .

للأسف لايعمل بالشكل المذكور والمعلن ولا يغدر يشيل تراكم الصداء 👎🏻

I have very hard water. LimeOut is the only product I have found that gets rid of hard water and iron stains and build up.

Price was high

I have tried just about everything on my tub and tile. We have hard water and the bathroom is 40 years old. Nothing was working no matter how much I scrubbed. I tried this as a last resort and it works very well. I still have to scrub but that is totally understandable given the state of the tub and tile. Everything has come oue clean and even the grout whitened up again. I recommend this if you are having a difficult time.
