Citric is hopelessly slow, but safe. Use it boiling to wake it up.
Hydrochloric is fast but eats anything it sees. Sulphamic and
phosphoric somewhere between the 2.

What about the descaling powders/gels available? Are they not worth the
money?

Look to see which acid is in them. some are sensibly priced, many are
silly. For the HCl or sulphamic acids, toilet cleaners sometimes are a
cheap source. I'd expect to pay 50p for citric (chemist is cheapest
source) and 80p for hydrochloric (some bog cleaners)


Note acid is somewhat incompatible with eyeballs - well, I dont know
who's reading this.

I will try to remember not to pour it into my eyes, thanks!!!

all liquids splash in use, so its going to take a bit more precaution
than that.
