Hi
My new 10L BM has this blue deposit. It is hard plastic and I cannot remove it. What to do ?
Thanks for your help :-)

Welcome aboard.

I can say it's not normal.
I would have a word with the supplier? IMO it's not new. Had it been used for something else?

It will (should) be possible to remove one we know what it is. First thing I would do is turn it over and strip the pump and fittings off. That way you can inspect them & work on it better if you are keeping it.


What have you tried?

Have you used it for brewing before without a problem?, if so this would indicate something dropped into the BM and got boiled.
When you magnify the image so the pump inlet is huge, lots of blue residue can be seen clinging around the sealing washer.
I think this indicates whatever it was broke up due to heat, is the any of the blue residue in the tap?.
I would do as Mashy suggests and remove the pump and fittings, then I would place the metal parts with blue on them in a pan and get them back up to boil and see if it scrapes off.

The nice thing is that the fittings are stainless, so there is loads we can try and little risk on damage.

Boiling.
Acid soak.
Caustic soak.
Acetone soak (nail varnish remover)

A shotgun cleaning wire brush might come in handy too.
If we get that far I can work out the size you need.

If it's new I would bring it back. This stuff should not be there.
Do not try to clean it yourself, you have years of guarantee and good speidel service.

Speidel says it can be removed with acetone. I did but that was NOT easy :(
