Pro-Kleen Fresh Water Tank Cleaner (5 Litres) - Sanitises, Descales, Removes Algae & Bacteria - Prevents Stale Taste & Odours

Really good product easy to use. It could do with a nosel with it though to get it into Motorhomes water tanks

I can say it works. I knew I had a weak pressure relief valve in the hot water tank and this made it completely fail. Thats a good thing because it basically removes all the rust and rubbish that was basically holding the inside of the valve together. The valve was going to get changed because I knew it was had it, but if it cleaned that, it's cleaned the tank. Lots of rubbish came out of the taps when flushing. I did leave it is a bit longer than the instructions said due to outside factors, but only an extra 12 hours. Bottle says leave over night.

Good product as far as sterilising the container but did not remove black spots on inside.

easy to use does the job

Used once so far really happy . Tank had been left without cleaning for a while ,very bad smell . Followed instructions and have been pleasantly surprised by no smell or bad taste . Excellent Thanks .

Used it to sanitise the potable water tank on my RV. Easy to use and works well. The low mark on the 'flavour' rating in my scoring is no reflection of the product quality, but the solution needs to be fully flushed out of the tanks and refilled with fresh water before drinking.

I'm not sure this product did anything. I followed the instructions and if anything, left it longer than required. No visible differences and no after smell like you would get with Miltons or similar. Still a bit of scale on the tap where the water comes out despite wiping it with neat solution out of the bottle.

The item did what it said in the instructions.. The system was flushed as directed and we now have clean water from the water tank in the loft and all the 25 years of sediment removed.
