Use Clorox bleach shower spray. Make certain to leave windows open or wear a mask. Leave on a few minutes, rinse off and dry with clean towels.

Is it mouldy?

If so, use a mixture of oil of cloves and water, leave it soak then rinse, the mould will die and no stains.

If it's a hard surface use 1/4 teaspoon of Oil of Cloves per litre of water, put it in a spray bottle, lightly mist on and leave overnight and wipe off.
