I have this stubborn calcium deposit stuck to my toilet bowl, and I've

clean it with and nothing seems to work. I actually got some of it to

anything safe I can use that'll dissolve the calcium deposits that isn't
a nasty acid of some sort?

When you get tired of spending money on products, various acids will
work. Why are you adverse to using acids? You could remove the
calcium in a minute or two.


I don't want to damage anything accidentally by using an acid, but if
that's the only think that'll work, what would be the safest one to try
first?

White vinegar is the mildest to start. Is the calcium under the water
line? Under the rim, clogging the rim jets?

You can progress to others but two cups of pool (muriatic acid) acid
poured in the bowl, brushed around with a nylon toilet brush and then
neutralized with baking soda before you flush -- in case you are on a
septic system or cast iron sewer lines.

More details are needed.

gee ... that sounds dangerous for me to try, anyway. I'm thinking that
trying a less dangerous acid might be better for me.
