Water Tank Cleaner
Tank Cleanse Pro 200g
Clean Water, Wherever You Roll
Why this product?
Stagnant water inside caravan, motorhome, and boat tanks doesn't stay fresh. Over time it builds up algae, mould, and bacteria that give your water a bad taste and smell — and can make it unsafe to drink or cook with. This is especially common after periods of storage.
- Cleans, destains, and sanitises in one treatment
- Concentrated formula — 1 tsp per 5L of capacity
- Treats up to 200L per 200g tub
- Removes algae, mould, and bacteria build-up
- Suitable for all freshwater tank materials
- Ideal for caravans, motorhomes, and boats
About this product
The Coast RV Tank Cleanse Pro is a concentrated water tank cleaner, sanitiser, and destainer designed for freshwater systems in caravans, motorhomes, and boats. Over time, stagnant water allows algae, mould, and harmful bacteria to build up inside tanks — affecting the taste and safety of your water. A single treatment with Tank Cleanse Pro eliminates that build-up and leaves your tank clean and safe.
The concentrated formula means one 200g tub treats up to 200L of water, making it one of the most cost-effective tank treatments available. Use it before storage, when coming out of storage, or any time your water smells or tastes off.
Why this beats the alternatives
Tank Cleanse Pro is a highly concentrated formula, so one 200g tub treats up to 200L — far more than most off-the-shelf alternatives. It cleans, destains, and sanitises in a single treatment, so you're not buying or running separate products through your system.
Who it's for
Caravan, motorhome, and boat owners who want to keep their freshwater tanks clean and safe — particularly before or after long storage, when changing seasons, or when water starts to taste or smell off.
- Work out your tank capacity in litres.
- Measure 1 teaspoon (approx. 5g) of Tank Cleanse Pro per 5L of tank capacity.
- Add the powder directly to the tank or dissolve in a small amount of warm water first.
- Fill the tank with fresh water and circulate through taps and lines.
- Leave for at least 30 minutes — or overnight for heavy contamination or long-term storage.
- Drain and flush the tank with clean fresh water before normal use.
