Scotch Corporation 1806 Instant Power Toilet Tank Cleaner by Scotch®

My euro type cistern flush valve was affected by scale and had the classic constant dribbling leak into the toilet pan. It was built in and very difficult to access and clean by hand. After using this all scale removed and no longer leaking. Saved me a large plumber repair bill.

Fast delivery and this works extremely well.

The product worked well in removing accumulated hard water deposits on the tank and fittings. In our case however the flush button has proved to be our problem and we have had to replace the complete unit

For me works I cleaned the built-in ones it was leaking, my only problem was to scoop in because the hole is small to just chuck in, but after few hours not leaking anymore from the limescale so I happy with that unfortunately can see difference inside because I can't see in but for limescale removed so should everything else es well.

Doesn’t work, don’t waste your money. Actually says guaranteed to work!!!!! Really

Worked for me in some extent

Was looking for something to clean my toilet unit as the flush was staying open....and this product worked a treat 3 months on and still prefect would definitely recommend trying this if you having same issue and each tub is 2 cleans as I use half a bottle each time. I only did one clear... perfect!!!

Didn't find it that helpful as it didn't cover the tank to the top where needed.

Parece magia, mis tanques estaban completamente sucios, negros de uña temporada que nos estuvo llegando agua sucia, no se podía limpiar tallando las paredes. Use este limpiador y en menos de dos horas ya estaban totalmente limpios, para asegurarme lo dejé el tiempo que mencionan. Totalmente recomendable, funciona

النتائج مذهلة

Update: I honestly forgot all about this product until I was cleaning out under the sink and found the second bottle I had. Which then quickly had me check the tanks to see them getting gross again so I made sure to get pictures this go around. This powder honestly had my tanks clean within like 15 minutes and all I did was dump it. If I wanted my tanks 100% clean I'd have to hand scrub along the water line but I'm not that extra. But I've attached the before and after pictures. Let me set the scene. One day, I wake up to use the restroom and notice the water is slightly brown and has something in it that looks like coffee grounds. My first thought is what the heck? Why would my husband dump coffee grounds down the toilet but he hasn't drank any in a long while, and I don't at all, so that stopped that theory. I flush whatever it is and think that's that. Wrong! This time the water is even darker so now I'm investigating. Our towns local page didn't post about any water issues so it's gotta be a me problem. Water in the sink runs clear so it's a toilet issue so that's when I looked in the tank and was greeted by black slush like mineral build-up. Yes, I also realize I should have just checked the tank first but adhd. Anyways, so since the toilet is next to the shower and we have a shower head with a hose, I decide to try and rinse it since it came off the sides of the tank when I touched it. Well, water alone didn't cut it so being the busy mom I am I let it fill back up with water and dump bleach in there. Didn't do a whole bunch even after sitting for hours so moving on to the next thing. This time I tried oxy and again letting it sit. After a few hours the bottom of the tank was clean but the sides still had residue on them and I didnt feel like scrubbing them. A quick Google search led me here and I figured why not. After all, my goal was to just dump something in and having it cleaned with chemicals vs me spending 10 minute cleaning it myself. Read the instructions and you use half a bottle and let it sit overnight. We'll, I really wish I would have gotten a before picture because this thing cleaned the whole thing and I didnt have to lift a finger. I didn't even have to wait all night, for me, it cleaned it within an hour. The only thing that's still dirty is the faint line of where the water ends. That will take 30 seconds to wipe down though since I can just take a cloth and run it along the edge, if I even want to do that. We have 2 toilets and I did the same thing with the other toilet as well and it is clean as well. That one didn't get any chemicals to try cleaning it since I wasn't going to waste product on 2 toilets if it wasn't working. But yeah, 100% recommend if you have hard water and aren't using a water softener because it's an iron and other minerals that built up. As a busy mom, I never even thought to clean my water tanks as well. Especially since I've never had to do it at my other houses. But glad I found this product and it did what I needed it to do.

It cleans everything inside the tank including the plastic parts of the flushing mechanism. I used a few tablespoons of the powder and leave it for a few hours. The tank walls are restored to white and the grudge built up on the plastic is gone. The plastic parts are the hardest to manually clean because lots of the areas are inaccessible but visible. This powder just removes them effortlessly.

This worked perfectly. The tank was discolored from hard water and this cleared it right up!
