or is it to strong for the magnets rubber tubing?

i would use a 50% solution in a flowing recirculation system

or you could use this

in a diluted solution in a flowing recirculation system

Dilute acetic acid shouldn't hurt the tubing, but concentrated acetic is incompatible with latex. (Nitrile rubber is fine.)

If you use a weak solution, you should be able to get rid of the lime without harming anything.

phosphoric acid?
isn´t that a little bit strong?

[buffo]

The stuff Pat linked to is *dilute* phosphoric acid. In dilute concentrations it's no more hazardous than the vinegar (acetic acid) you suggested.

Even dilute hydrochloric would work. Go to your local pool supply store and they'll sell it to you in 1 gallon jugs labeled "muratic acid". Dilute 1 part in 10 and you're golden.

This is available world wide and is buffered chemically to prevent corrosion:

CLR is your friend and I've used it with no evidence of corrosion on brass lexel magnets and SP's wet anode. You circulate it diluted in a bucket with a pump or by hand. Then you flush it out. I would NOT run it through the flow switch for corrosion and clogging issues, well, unless the flowswitch is already clogged, ie Florida water.

On this side of the pond, we call that stuff Coca-Cola.

then i can probably use anything made for dishwashers, coffee machines, and washing machines?

can´t find any jelmar products in sweden or rest of europe

Maybe... It depends on what else is in the mix. Some dishwasher soaps can etch glass with prolonged overuse, so I'd hesitate to issue a blanket statement on all consumer products. But the alternatives listed above (including CLR, which Steve mentioned) have been proven to be effective without ill effects.

Here, enviroweenie approved version:

Perhaps not as strong as CLR:

If that doesn't do it. reach for some vinegar
