Hi Guys,
I rent out a property and the toilet bowl is heavily limescaled in
the pan below the water line. What is the best product/solution to
remove it?


I use DILUTE!!! Hydrochloric acid. Use rubber gloves and eye
protection. Open the window first. Chlorine gas is given off as it
reacts with the limescale.


It shouldn't be.

Carbon dioxide is given off actually.

Leaves the pan as clean as a whistle. I'm not sure where you get
it in the UK, builders merchants perhaps. In France you can get it in
any supermarket.

Its called brick acid or patio cleaner.

Use a plunger first to flush out most of the water, then add the acid
otherwise part of the acid will go straight down the drain.
If necessary, top back up to the normal flush line with water.

Hydrochloric acid is the correct stuff as the reaction product (calcium
chloride) is soluble in water. Don't use battery acid (sulphuric) as the
product, calcium sulphate will form an insoluble layer over the rest of
the limescale and slow down the reaction considerably.
