I've just pressure washed the patio but it's still not clean. There are a lot of very stubborn algae stains that won't budge. Can anyone recommend a patio cleaner that works. I've tried Jeyes and a couple of others from B&Q over the years but nothing has really lived up to its claims. It has to be safe to run off onto flower beds and with animals.
This is not a bad product Ratty. I will post the safety data sheet separately. You can order it and pick up from a local B&Q. I have an account with Screwfix and they are very handy.
Patio Magic from Amazon. It's safe for animals. I used it and thought it had made no difference the first day. Within a couple of days it had totally disappeared.
Ratty I have the same problem as you and I have pets and don't want to kill the creatures that venture into my garden, well, except the slugs. I have gorgeous white slabs and the only way I can get them clean is to literally scrub them. Hard work but nothing else does it. Sorry:-(
Lady speaks the truth there. We have a riven sandstone patio and although some cleaners are better than others we find that boiling water is the first treatment, then a cleaner, and if needed a good scrub with a warm water/mild bleach solution. This year was particularly bad due to the mild wet winter.
