What use is Bleach?

If you watch any of the forensic crime shows on TV you will know that many murderers attempt to clean the crime scene with bleach, as though it is a cure-all for any stain.

You will also have noticed that it usually fails, and they are caught.

The reason is that bleach is actually not very good for cleaning at all, and in fact I don’t recommend it for anything. It is a (very strong) oxidiser, and that’s all. If you want to remove stains by oxidation, any of the “oxy action” products will do the job without destroying the fabric.

And when it comes to cleaning mould out of your shower recess, or anywhere else, an oven cleaner will do a better job than bleach. If you want to disinfect things, 70% (or higher) metho will do the job.

But you still need it in pools ans spas – at about 2ppm it is a very effective biocide
