Grab some Sodium Hypochlorite (super strong bleach) its what professional cleaners use on driveways and patios
Have a look on youtube and Amazon for reviews
Job done, no chemicals just some plentiful water and probably 20p of electricity
I got patio magic on the way for now
but the strong bleach sounds like the best idea. so i will look around for that
how many times a year are y'all cleaning ya patios?
Wet and Forget <<<<< you will read up about it and think its some sort of gimmick, but it is amazing stuff, will take weeks before you start seeing a difference, gave the slabs in the back garden 2x coats, a month or so apart, and it's been 4 years now, and nothing has came back
Bleach is sodium hypochlorite. The professional stuff is 15% strength whilst the jog standard supermarket bleach is usually about 5%.
For a small domestic job I’d just buy a few bottles of standard bleach and brush it neat onto the patio. Let it sit for a good half hour then thoroughly rinse it off. Don’t do it when it’s hot and sunny, keep children and animals off it while the bleach does its job, and don’t get any on your grass or plants.
A bit?! How many millions (billions?) of litres of drinking quality water are wasted washing things that don't actually - if we're being honest - need washing? People washing their patios, driveways and cars for godsakes when the reality is they could all be done with much less water and a bit of elbow grease, and quite frankly who on earth needs to wash their car?Why are they bad for the enviroment aside from a bit of electricity and water?
