Heating acids does not neutralise them.

It's the dissolved CO2 that makes the water acidic shit-fer-brains. Pure water is considered neutral.

You tell us heating acidic water makes it less acidic, which is more utter bullshit shitferbrains

It should dissolve readily in hydrochloric acid (brick acid). Other descalers may work, but perhaps be slower.

I'll try that next time I have a shower. Thanks for the tip.

Might sting a bit, I'd use something milder to wash with and use the acid on the mark later.
