Removing Limescale tip !
This is a tip that I got recently from a Tap Manufacturer where a customer was trying to replace his Valve.
He had gotten his handle off but couldn’t remove the shroud (also known as locking nut / fixing nut / hood that covered the valve due to the buildup of limescale.
Removing Limescale Tip :
Soak problem area in a solution of lemon and water (equal proportions) for maximum of 30 minutes.
Rinse off solution completely then.
Repeat this process as often as required to remove the limescale – but always only to a maximum of 30 minutes and completely wash off solution in between)
If in doubt as to the finish of your tap, you should test on a tiny bit first where it won’t be seen.
