How to clean a stainless steel water tank

You could fill it half full with water, then empty a litre or so of household chlorine type bleach.

Then fill it up and leave it soak for a couple of days.

Drain and rinse till you can't smell the chlorine any more, then drain it and fill it again and taste it to make sure.

I used the Milton baby bottle streilizing liquid to clean the tank then rinsed several times. Clean the filler & drain hoses as well.

Why not just use tank cleaning tablets?

My water tank picked up some black fungus at one stage when I topped up from a country town water tank.

I used Bi-Carb soda - harmless to humans. Just mixed up a strong dose of about 200g in half a litre of water and poured that into the tank. Filled the tank up to full and drove around for a few days.

Did this 3 times and it came perfectly clean.

Bi-Carb soda or baking soda can be purchase at your local supermarket by the 1kg for only a few dollars. This is the basic ingredient in baby bottle cleaning stuff and the beer bottle cleaning stuff. Also the same basic ingredient in the tank clean you can buy from caravan shops. These others are just expensive brand name products.

Bi-carb soda has been used for years for cleaning and disinfecting before manufacturers came up with fancy brand name products.

Does leave a little taste for the next 2 tank fulls but is totally gone now.

Use the same stuff that I use to clean stainless steal home brew kegs which is plain bleach ( not lemon ) tip 1/2 l in tank fill with water leave for 1 hr drain then fill with hot water and drain this will kill the chlorine that is made by the bleach

try salt heaps of it,,, say 1kg to 100 litres

fill tank and let it slosh around,,,

leave about 10-20% water in tank and go for a drive with drian OPEN to take away the dregs

RINSE the same as above

should do the trick UNLESS you have bacteria in the tank and then you may need to consider other treatments but try the salt first

Thanks for everones advise.
