Advice your mom to use muriatic acid (HCl) to wash of this white residue

I see the smilie. Are you serious?

It will react with calcium in this white residue and chemical reaction
will form calcium chloride, which is water-soluble and it will be easy
to wash it from the wall with a garden hose...
Use small quantities and wear protection clothes and safety glasses.

Are these the results of, ahem, empirical testing, Wayne? ;-)

(FYI, HDPE holds up pretty well to silute solutions of HCl).

Also the swing arm in a hydrometer, is nylon.

If you find that your carpet is too soft, just poor some hcl acid on
it :-)

And then you will have a lump of hard melted plastic, instead of soft
carpet :-)

ughn, "silute" = "dilute"

hehehe well I made the mistake of cleaning a nylon
plumbing fitting with hcl, and once dripped hcl on a
carpet like toilet seat cover. I've never made the
mistake with a swing arm hydrometer, but I'm pretty
sure it's nylon. One way to find out :-) The bottles
that the hcl comes in is HDPE. It holds up for a
while, but even it starts showing signs of blisters,
in time. I have a small drip bottle (empty aquariuum
pharm ph ) that works well for hcl. But it is now so
blistered over the years from the hcl, that it looks
like it has the measles, it's totally covered with
bumps, and bumps on the bumps :-)
