Dilute into a 5 litre pressure sprayer. Spray onto a dry patio Ensure there is time for it to dry before the next rainfall When it rains, enjoy your newly cleaned patio.
No need for a jetwash with this. I use this twice a year and jetwash once every one or two years depending on the weather.
I've got some not used it yet, could it be used to stop algae growing on a wooden fence in the same way?
Any recommendations for a cheap pump sprayer I can keep specifically for this please
Or just use diluted BAC50 as I've linked above for a fraction of the price.
Why do you need a cleaning solution as well, doesn't the jet washer get the green off?
My fathers uses sodium hypochlorite in 20 or 25L plastic containers ...can remember the concentration but the make usually has been Brenntag. (but its the chemical not the brand thats important...Im sure there are other brands) He puts this on neat onto the indian stone and brushes it in with a sweeping brush leaves for a few hours and then washes off with a hosepipe.
You can buy it at agricultural / farm supplies shops as I believe its used to clean down milking parlours etc.
Less than £30 for 20 or 25L
This. 25litre Sodium Hypochlorite from Wynnstay Agricultural suppliers. I dilute 1/2 - 1/3 strength and apply with a watering can. Take care when handling.
