I couldn't find any bath power so I thought I'd try Ciillit Bang's Active Foam. Oh, my! I just squirted it round the bath, shower and sink. Then I walked out for a few minutes, came back, showered the bath and shower surround, swooshed some water round the sink and my bathroom is gleaming! The manky tile grout is much whiter than ever before. I didn't believe it would get that clean without some effort.
