Muriatic acid is concentrated HCl. Already tried that. Didn't work.
Also burned several small holes in my clothing. I wouldn't bring that
stuff anywhere inside the house again. The fumes would react with the
copper plumbing for example. Also I can't buy this stuff at the
hardware store anymore. Its classified as a harzardous substance. I
have other sources for strong acids. I don't have any call to get any
after experiments didn't clear the lime build-up. As for another
comment on a lifetime build-up of lime, I have to do this lime
scraping removal two or three times a year.


Muriatic acid is still being sold where I live. I use it to clean the DE
pool filter, and it can be dumped directly into the pool to lower the
PH. Go to any pool and spa store to get some if the hardware store
doesn't carry it.
