Just done a long overdue overhaul of my bathroom. You know the kind of thing: new silicone seals, clean up grouting, new taps and so on. The bath had developed a film, presumably a mixture of soaps residues and calcium carbonate. Anyway it wouldn't come off with strong detergent. Then valiant assistant, otherwise known as son, told me to try bio washing powder. 'Fill the bath up with warm water and then put in lots of the powder', sez he. Tried, and hey presto brilliantly clean. Just thought I'd share it.
To clean up the shower curtains, which were *bad* I put them in a large sink and poured full-strength thick bleach on. A bit of water then a good few stirs to make sure all the muck got done, and they were as good as new. I thought it might damage the fabric, but this is the second time I've done it and all is well.
