Powerplus Original, 500 ml

I had read on an online group I belong to that this was great for toilet stains that typical toilet cleaners wouldn't remove. I thought I would give it a try as I have 20+ year old toilets in my house that the hard water has caused a ring in the toilet. I followed the directions and it worked fantastic! I did have to repeat on a stubborn stain on one of my toilets but the other three toilets it worked great the first time. I would definitely recommend this product for hard to remove toilet stain from hard water.

I first learned about this toilet bowl cleaner in an article I read online. I look for it on Amazon and it was available but would take about a month to arrive. I'm not sure why it took so long but I finally arrived last week. My first use of it was on a plastic potty chair that had been stained with mineral deposits because the pee was not immediately rinsed out of it after being used. The nice thing about this product it is more like a gel than a liquid. This allowed it to coat the sides of the potty as well as the bottom. I put it in and let it sit overnight, then used a toilet brush to swirl it around and was quite astounded to find that the mineral deposits were gone. I rinsed several times to remove the gel. When my daughter noticed how clean the potty was, she called me to find out how I had managed to get it so clean. I also plan to try it in an old bathtub that has mineral deposits on it. I'm hoping it will be as effective there as it was in the potty.

To remove the hard water stain on the sink, I tried several products but it didn't work. This one worked! I just soaked it for 15 min, and it was wiped out easily. The yellow discolor is still there but the hard water stain is gone. So I am satisfied.

I do have a lot of rust in my water and it does eliminate some of it. My cap is very dis functional and messy. Maybe I’m not opening it right but shouldn’t be that difficult to figure out if I’m not. A stronger chemical i would rather not get on my hands every time I open the bottle to use it.

Is expensive but it does work. I think if you use it 1-2x a month with basic toilet bowl cleanings and products it will keep the hard water rims away.

This product cannot be returned!!!!!! IT DOES NOT STATE THIS IN THE POSTING. The product contains hydrochloric acid, which can destroy older plumbing from before 1995. We bought this and never opened it, because we read the contents and decided it was too risky to use in our 1989 home with older plumbing. I attempted to return it and got a message that this item cannot be returned. WHAT THE HELL? The post doesn't say anything about no returns or the acid issue. On top of that, this is a ridiculously small amount of product for $16.00. We don't want it, and we never opened it, so what is the problem? I now have contact Amazon and get my money back. RIP OFF!!!!

Fast acting for thise stubborn toilet stains. The entire bottle may not be needed depending on the stain. I covered the toilet bowl with plastic wrap, because of the fumes and let it sit for most of the day.

If you have hard water. Calcium build up! This dissolves it in seconds. Heavy build up like years of build up.. let it sit over night next morning it falls right off. Love this product.

Good Quality

Harpic is a staple in the U.K. and Ireland, and deservedly so. It rids the toilet of stains with very little effort or brushing, and lives up to its reputation of cleaning 'right round the bend.' It's quite expensive, and takes a long time to arrive, so that we wish it were more locally accessible - I think this shipment originated in India - but worth the wait. Not much is needed for a thorough clean.

The best in the game.

The harpic is good quality and cleans effectively toilet bowls. Do not use for taps and mosaic tiles as it is acidic and damages the material. Value for money

Amazing results every time. Worth every penny. A++++
