In case you guys take the staging a little further:

Here's a quick and easy recipe for  Mould & mildew stains around the bathtub

I really notice this when I do consultations as I'm sure the potential buyer will too.So either hand the recipe to your client, or roll up your sleeves! (Add the labour cost to your staging fee!)

To remove the mould that grows in the caulking around the bathtub, treat the area with a strong solution of chlorine bleach (2 oz. bleach to 1 c. of water). Use the bleach solution to remove any black mildew stains from the tile grout too. Apply with a stiff brush.
