calgon

isnt that medicine for kids

i usually remove the bottom immersion element and use a wetvac

megaflows and santon have quite small holes for the immersion, in this case i didnt have enough room to get the wet vac in

oh i did that :yesnod:

Vinegar, strong vinegar

I was thinking that, my missus does it to the kettle and it works, have you tried it on an unvented tank

Diluted phosphoric acid. As is recommended for stubborn deposits on Viessmann heat exchanger's. Most commercial janitorial suppliers will have a variant. But you do need to be sure you can flush it all out when you are satisfied its done its job.
Critic acid powder is equally easy to buy but has the advantage of being food based, or you could use any coffee machine fed valet but when they are branded as such they tend to be expensive for the same ingredients.

Phosphoric acid more readily available than hydrochloric, which could formally be purchased for cleaning bricks. Now what passes as brick/patio cleaner is too dilute.

Try taping a flush pipe from a low level wc to the end of the wetvac tube, cut to the right length it works well

Fill it with kamaco de scaler Boil and flush. Fill it, disconnect dcw and leave hot tap open - gas to escape.

Flush it's nuts off or 2l of 40% phosphoric

Was reading the ingredients of coke life yesterday as had not seen it before it has a green label, amongst the ingrediants mainly sugar and sweeteners was phosphoric acid, apparently equally good as a refreshing beverage as an lime scale remover and toilet cleaner.

At our company we acid in one those central heating power flush barrels. Connect at inlet and outlet of cylinder, circulate for an hour, then flush several times with clean water.
