How do you remove calcium deposits from a porcelain sink?

Answer 1

Try vinegar and a scrubber, or commercially prepared 'Lime Away'. The trick is that a weak acidic solution should dissolve the calcium deposits.

It is advisable not to use acid cleaners on porcelain sinks. The top surface can be gradually dissolved by acids and expose the layer underneath and cause a lot of damage.

Natural Formula to Use:

A mixture of baking soda and warm water

Method to Use:

1.Make up the mixture of water and baking soda

2.Scrub stains with a soft brush or sponge

3.Rinse thoroughly with water to remove all residue

Tip:

When scrubbing the stains be careful to rub gently as once the surface has been scratched it easily picks up any grease, dirt or soap residue.

Answer 2

From the hardware shop, purchase a liquid called Spirit of salts, this is an acid which can be poured over the calcium to dissolve it. Take care not to breath in the fumes though as they are damaging. Best to remove as much water from the bowel first then gently either pour over the stains or use a face mask and an old paintbrush with some acid and rub away at it. It generally comes of pretty easy but may need several attempts before its all gone. Flush between re-applying.

CLR is sold in most grocery stores. Works very fast.

use with a scratch free scrubbing pad. Do not get this on any crome finish because it will take the shine out.
