Can anyone out there offer any advice what we can use on our front driveway to get rid of the green moss, which seems to have taken hold after this very wet spell. Normally we use a mixture of disinfectant and water, but as it's such a large area, wondered if there is something else?? Hope you can help, many thanks, best wishes, Chox.
I use a product called "Dairy Hypochlorite" for my patio.
It's roughly £15 - £20 for a 25 litre drum.
I won't use anything else now - not even my power washer; as this once removed a green patch that my power washer wouldn't remove.
The first time I used it, I brought my neighbour round to show her - it literally came up like new .... I can't rant on enough about it .... and no I'm not on commission lol :)
as gizmonster says, dairy hypochlorite cleans virtually anything. iv'e been using t for 35+years and swear by it. brilliant for 'green concrete' as well. some people dilute it but i always use it neat in a watering can with a rose with small holes
Shake a couple of packets over the drive, or however much it takes to cover the area reasonably generously. Leave for a couple of days. If it hasn't rained within 24hours then damp it down with a watering can. The moss will go black and can then be brushed away.
margo tester, with concrete i pour it on leave for 30 mins or so then hose off. on tarmac with moss i usually pour on and leave overnight then sweep with a stiff broom, it'll be interesting to see what gizmonster says he may have an easier way
I dilute mine - can't remember exactly, but I think I dilute it 1 part DHC and 5 parts water .... ish.
I use a watering can to apply it. I usually brush it in - no need for vigorous brushing, just brush it to agitate it. I then leave it for approx 30 mins then rinse off with a hose .... comes up a treat and a lot less effort than using a pressure washer.
Margiotester this is where you'll know more than me , it is just a strong bleach but I'm no gardener I used to sweep it off the concrete onto th grass, it soon recovered but I wouldn't know about flowers
