I wondered a few days ago about Doff patio cleaner,and would it really work, so tried a small but yucky green part of the patio, very sceptically I have to say, and lo and behold! 24 hours later the green muck has gone, and other yuk much cleaner, so will proceed with the rest of the patio now
Do you have a power Washer? I have done many patio's when valeting, get the cheapest Soap Powder that's around before you sprinkle it around your Patio, Dampen the whole area to be cleaned & then sprinkle the powder & leave for 1/2 hour then power wash off.
Up till now I've used power washer, but it's got to be hard work at my age !!! So tried this, then will probably give it a quick go over with the p.w. Later. OH has a bad back, so can't help, and it's always been my job as I like seeing everything clean after my hard work
Mags, the power wash I have only came with a short lance ( Gun) I do not have back prob's was a pain doing Patios, I purchased an Extension for the lance "Job Sorted" have a look on ebay to see if you can get an extension for your machine, they are not that expensive.
