Amazon were doing 4x5L of vinegar for £6ish at chrimbo. Guess which one got used to clean my paths and patio. They're still flogging it but it's now £12 but I wager it still better to buy 20L of vinegar rather than 2.5L of this stuff.

This stuff is absolutely pants, your better off using water and a scrubbing brush.

Hot price for patio magic but Aldi do similar stuff for half the price.
I love how this stuff keeps working for months.
Haven't tried the Aldi alternative mentioned - I might give it a go.

Is that how you clean your pants ?
This stuff's active ingredient is benzalkonium chloride, it kills moss and algae dead. Pour it on, maybe brush it a bit, wait a week or so, it's all dead. You can either leave the dead stuff to be washed away in the rain or brush it off.
Have used this stuff on Indian sand stone and it does work, killed the green stuff... but the claim that it stays always for a long time is not correct, prolonged wet periods and it soon comes back..

For algae (green and brown) it's a 'wait overnight' job for us. Huge difference, and just gets better over the following few days.
For those who need a *lot", you can get pure BAC at 50% concentration for about £30 for 5 litres. Patio Magic is 7.5% BAC so it'd work out well under half the price.
Wilko green gone super concentrate is same active ingredient, only 6.25% but works out a bit cheaper per litre and don't need Prime

So how well did the vinegar work? Did you have to scrub or just leave it on?

Nip down to home bargains and buy soda crystals for 65p ,sprinkle it on leave a while then water in ,if no rain .
Kills moss stone dead . With no bleaches no harsh chemicals .
If you don't have Prime, or want it now, it's only £7 at Wilkinson.

I use a 25% vinegar 75% water solution, brush on with a stiff brush, leave for 20-30mins,then hose or jet wash off. Although jet washing will clean surfaces it will leave some microbes that start the growth earlier than would otherwise happen; using the vinegar kills it all, loosens it up, and makes the hosing or jet washing to clean up easier.

I second that, used vinegar as well (just like other cleaners but without pressure wash) but why pay over £12 + shipping for 20 liters when you can buy the quantily needed at your local Polish grocery shop where a bottle costs as little as 35p (0.5L of 10% vinegar = 1L of the usual 5% vinegar)
Also there is nothing magic about the Patio Magic, it does a reasonable job and does not last - waste of money
