The shell (Calcium carbonate) dissolves in acetic acid and forms water and carbon dioxide.
CaCO3 + 2 CH3COOH --> Ca(CH3COO)2 + H2O + CO2
To remove mould from clothing you can try to soak the garments in vinegar (diluted acetic acid) for a few hours then wash them normally.
1 cup vinegar to 5 cups water is typical ratio. Pharmacists generally supply a 2% dultion that is also used.
soak them in acid
The hydronium concentration is essentially soaked up by the buffer system. Being that there is an equilibrium of acetic acid and acetate ion, the acetate ion will soak up an H+ from the HCl, and then the equilibrium of acetic acid to acetate ion shifts in favor of the acetate, because its concentration is lowered. The result is that the change in pH is dramatically lower than would normally be expected by adding HCl to deionized water.
Mix baking soda with water and carefully pour it on the spill, to cut the acid, then soak it up with rags and throw the rags away.
the acetic acid in the vinegar would slowly dissolve the iron and produce hydrogen gas
Yes. Even dilute acetic acid, vinegar, can dissolve eggshell. Try this experiment: put a raw egg in vinegar for three days. The shell will dissolve but the egg will still be intact in its membrane. You can remove the egg and it will be rubbery. Handle delicately - the membrane is thin and easily torn. You'll also notice that the egg has swollen - the membrane is permeable, and the vinegar will penetrate into the fluid parts of the egg, swelling it.

Yes, vinegar is just acetic acid (CH3COOH) which means it will clean the ring and because it is a weak acid it would not be able to turn the metal into aqueous solution (liquid).
Capiz shell does not have to be soften, the shell is already very thin and flexible (also called paper shell clam).

ketchup - the vinegar ( acetic acid ) in ketchup changes the copper oxide to copper acetate which is soluable in water.
Vinegar (acetic acid; CH3COOH) is a mild organic acid. Since eggshells are rich in calcium, it reacts with vinegar spontaneously to produce calcium acetate (CH3COOCa). This ultimately results in dissolution of eggshell with liberation of H2 gas.
The dilute acetic acid sold as Vinegar will make a steak more tender if you marinate the steak in it for a few hours before cooking. It will also carry flavorings into the meat, so if you use the right kind of vinegar--balsamic or red wine, not "distilled" it gives the meat a really nice taste. If you buy glacial acetic acid--it comes from a chemical supply house or an old-timey camera store that still sells darkroom chemicals--and soak the steak in it long enough, it'll dissolve. But what's the point of that?

Soda pop will dissolve the calcium in the egg shell.
