hard water deposits

Post by Secla » Tue Jun 07, 2016 10:34 pm

I get hard water deposits left on my stainless boiler after a brew, Does anyone have any tricks on how to remove ? I don't really want to use a scouring pad

Cheap supermarket lemon juice or white vinegar. Just wipe with a non scratch scouring sponge.

I also go for the Starsan. I find the deposits appear a few days after brewing once all the water has dried out. By that time I've got lots of starsan solution knocking around. I know some people manage to keep Starsan for weeks/months but whenever I've tried this the bottom of the FV lid goes all mouldy which puts me off using so I just dump it. Nowadays I dump it via the kettle. I've got a little recirc pump I use for sterilising the boiler tap so I just use that to spray the starsan all over the sides of the kettle. Makes it good and shiny.

Reducing the alkalinity in your brewing water makes life a lot easier as you don't get the same level of deposit. I can usually spray the crud off my elements for example with very little scrubbing needed.

This. Doesn't work retrospectively though. Image

My water is quite hard (230ppm CaCO3) too. After cleaning kit my final rinse is with a weak citric acid solution (made up with my tap water). Starsan is fine (although I make it up with soft bottled water), but citric acid solution is a bit stronger and makes things nice and shiny.

Jocky, when you say weak citric acid solution, what amounts we talking?

About a tablespoon in 3 to 5 litres.

Not sure of the actual strength if I'm honest.

Cheers. I'll also give that a go next time. I've only cleaned the element with citric by boiling with a few litres but everything above that has a white misty coating.

Oh you definitely don't need to boil the element to clean it.

A bit of citric even in cold water should bring it up super shiny.
