How can vanadium staining on new bricks be removed and should the builder be responsible for cleaning it before handover?

Vanadium staining on new bricks can often be removed using a diluted hydrochloric acid solution, applied carefully to avoid damaging the brickwork. It is generally recommended that builders be responsible for cleaning off this type of staining before the property is handed over to the owner. Addressing this issue prior to handover ensures the bricks are presented in their intended condition.
