I am going to put a 16v header tank with the plastic screw top on, as I replaced my leaking one with a metal twist cap one.
It is a little dirty inside, last time I cleaned one of these I used sand and water. There are compartments that a brush won’t get to. I shook it vigorously and rinsed out thoroughly. This time I was thinking of doing the same and using gunk.
Anyone got any other ideas?

Maybe caustic soda or bleach?

Sand and water will make the interior surface rough and more likely to encourage deposits, and is difficult to get out again because of the baffles inside.

I use a product named FERRONET, which I bought in Spain.

I don't know if there is an equivalent in UK. It is sold for cleaning iron and steel, also for removing lime incrustation on sanitary ware etc. It is acidic, maybe hydrochloric, more likely a mixture.

Mixed about 1:2 with water and left inside with the outlets plugged, turning around occasionally to coat all the surfaces, it completely removes rust and other deposits, and even dissolved the small loose pieces of rust which I couldn't wash out.

Hi

One thing worth trying if it is oily dirt is to soak it in biological washing powder.

All the best

Didn't think the sand would do that, good to know, wont do it again, last time I did it, I took my time making sure it was all rinsed out, did a really good job though and when i drained out my coolant, it was clear blue. I only have toilet duck “lime scale remover” to hand at the moment, which is being left over night until I get something else.

It’s the usual calcium / scale deposits coating the inside, cant believe how much crud came out.
Off to rotate header tank againg Laughing

Hi, i use salt and shake the tank until all of the crud has been removed. After this, I empty the tank and flush it with tap water until i'm sure all of the salt has dissolved. I wouldn't want to try with sand, because you're never sure no grain is left after cleaning, with salt you're sure! and it's cheap and harmless, and works a treat on rusty deposits.

I managed to get it fairly clean, using toilet duck and leaving over night. There are just a few bits left, so I rinsed it out and added some salt. I think I need one of these vibrating thingy’s as it doesn’t seem to be doing anything.
