How much to dilute bleach

Mar 06, 2013 12 Replies

Want to get the mould off some stone work and paving slabs.



Using standard household bleach from the supermarket, what is the best ratio to dilute it with water?



Since I read somewhere, a time ago; that *undiluted* actually is not as effective as diluted to a certain extent. Thanks.


Full strength is best for that

And this act will probably kill any garden where the run off goes. Brian

You will do better to go down the builders merchant and get a can of algy killer. More effective and the effect lasts a bit longer. But it will come back in the end.

Ring up first, you will get a better price.

BTW the stuff will kill it but it won't just vanish, you will still have to clean it off. (Pressure washer).

What happens to hypochlorite when it dries? Maybe it never does, and carries on attracting moisture. Certainly has a high PH for some reason. Sheer laziness on my part. I should read up but I probably won't understand what I'm reading.

I don't know about what happens in a lab, but in the environment, it will probably end up as oxygen, salt, or chlorine (which is only a problem in large quantities).

I believe that's basically true, though wikipedia suggests you can also get some chlorate.

The chlorine gas is evolved/dissipates and you are left with just water and a salt finally. Which can be beneficial in some cases.

Be careful using bleach as it will bleach the paving stones. Patio cleaner is best, though vinegar is cheaper.

Bleach is a good cheap weed killer.
