Don't put them in the washing machine you'll wash away the effectiveness of the Magic. Just hang them up and let them dry naturally. Empty the solution over your patio....double whammy:)

Patio magic is great at killing off the algae but doesn't remove it. detergent is great at removing green but not killing it. you need both to get lines clean and stay clean.

Disagree. Patio Magic will keep on working for weeks after application. You will see an improvement as time goes by. Washing afterwards will negate the effect of using it.

also disagree. (but only in part)

Once all the living stuff is dead it is still in the rope and will make it look grubby. on a deck ( or patio for that matter) rain etc will wash the dead stuff off. on a rope it wont as it's usually ingrained. To get it clean as the OP wants you then need to wash it.

The issue then is that washing it then removes the algicide residue which prevents further growth. Of course if the rope is dry and in the sun then nothing will grow anyway but not unknown for boats lines to get wet!

Perfect solution is soak, let the PM work for a few days, wash in a machine on a gentle wash with non bio and fabric conditioner, then dunk in PM again and let dry.

I wouldn't dilute ordinary Patio Magic by 9:1. It's probably OK diluted 50:50 with water. Any more dilute, and it won't be very effective.

According to Brintons website the standard dilution rate for Patio Magic for ordinary use is 4:1. For "light growth" it may be diluted 9:1. I'd class a little algae on ropes as "light growth"

Unfortunately the EU legislation does not allow it to be used for killing moss but at 4:1 it will kill moss on patios etc.

I keep some diluted at about 9:1 in a trigger spray bottle for general indoor use. A regular light spray keeps the bath/ shower mat mould free. Similarly the shower curtain.

Yes, as already explained in post #10 but I'd leave it a week or longer rather than a few days if you have time.

Thanks guys; I think I'll leave them overnight and take them out tomorrow. I like the idea of putting them through the washing machine, but doubt SWMBO will let me anywhere near her precious Miele!

The Miele is the best of all for the job, ours has been doing it for 17 years now without a hitch...

I think that an overnight soak followed by drying would certainly do the trick. Curiously, this year I left mine in 4:1 PM rather longer than intended (several days) and they stayed green! But having taken them out, rinsed them and put them through the washing machine (in an old pillowcase) they’re clean as a whistle.

PS With lines etc. on the boat I just brush on and leave, like dunedin.
Do what I do - wait till she's out.

So washing gets rid of algae, but doesn't prevent it, while PM and the like prevent but don't remove. In that case, surely the thing to do is to upset Management and the Miele first, then give the lines a good soak in PM afterwards.
That's what I do, wash halyards in a bucket of water with plenty of detergent, on deck, bring home sheets, jackstays, furling line etc and wash in machine. When dry spray with Patio Magic. Similarly with teak, wash first, then spray with PM. Lasts a season

Patio Magic is not very nice stuff, I spray the patio but take care to be downwind of the spray, otherwise it chokes. On a boat there are concerns about the effect on marine organisms. In any case, I prefer to brush it on my deck, using a soft deck brush and the PM in a bucket, which doesn't take long.

I spray it in the boatyard, and yes, I have probably been instinctively staying upwind of it. I turn the sprayer head to a fairly coarse setting when doing running rigging so that it mostly hits the target area rather than the surroundings.
