Has anyone got domestic-strength (about 4.5%) bleach to kill established
moss on a pathway?

If so, was it neat or could you get it to work when diluted - and at
what dilution?

I use it at about 50% diluted with caustic soda to kill moss and other
growth on my drive and patio.

If you are going to use chemicals to do it you might at least use the
right ones. Anything else will be almost a waste of time. Likewise if
the conditions are right for moss and lichens they will quickly return.

"Wet and forget" is about the simplest to use.

Don't expect miracles. The moss is there because of the cool and damp.
It will return next winter without fail.

That is probably a lower concentration version of BAC50.

BAC 50 prices seem to have risen significantly during our lockdowns but
should fall back to around £25 for 5L (incl postage), as they did after
the first lockdown.

I prefer to use biological washing powder, cheaper and just as
effective, also kinder on other things in and around the garden.

....is the right answer. I use four times the normal (washing)
concentration and apply it via a watering can. It's cheap, cheerful, and
effective. The moss I bumped off last October has just started to make a
much-weakened re-appearance, which was very easy to re-treat. I doubt
I'll see it again until November.

For small areas or difficult-to-reach areas I use the same dilution in a
used trigger-pack.

According to the MSDS, yes it is, single active ingredient
Benzalkonium chloride 68424-85-1 10 %

What would you reckon that works out as grammes of Bio Washing Powder to
a litre of water?

Just sprinkle the biological powder over the moss. You can wait for rain or mist it. Don't go hard on the hose or you'll just wash the powder into the drains. Good for at least one year or more I.M..

What amount of powder do they suggest for use in a washing machine? How
much water does the machine use for a main wash? The rest is simple
arithmetic...

I use liquid bio as we have some, and it's easier to mix, but you could
sprinkle the powder on directly, and either very lightly damp it or wait
for it to rain.


Only you have the data on which you based your statement, Spike.

Well, the data is that a 4x concentration of liquid bio watered onto
driveway moss made it go away, apparently mostly permanently.

I got the idea from a post on here late last year, which spoke of
builders who had replaced flat roofs, spreading powder bio onto the
chippings in order to prevent moss growth for a period of up to five years.

I hadn't got any powder bio to hand, and in any case didn't want my
tarmac surface covered with it, so decided to experiment by applying a
solution as described. In practise, about 10 percent of the moss
recently started to reappear, which was easily zapped with a
hand-sprayer of the type I mentioned.

Perhaps a 5x concentration might have killed it all, and if any returns
in Autumn I might try that.
