My sister has just bought a house and needless to say the previous owners have left it in a bad way. The bathroom in particular needs A LOT of elbow grease. The shower recess is very YUK. Black mould, the grout in the tiles is stained and there is soap scum caked everywhere.
What would you use to clean it up? She wants to use natural, household ingredients if possible to see if she can budge it first.
