I took my rather green and dirty lazy jacks of the boat today and I am now soaking them in a 4:1 solution of Patio Magic. I have not used this before and would appreciate advice as to how long to leave them soaking? Also, am I right in thinking that i then need to dry them so that the cleaning process can then continue?

Many Thanks
 
I don't think you need to soak them for any length of time - just dip them or paint on. Then leave to dry and do their stuff.

Certainly that is the approach I have used successfully to date (being a male I have of course not read the instructions :-)
 
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.

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!

+1 for the washing machine. I have found that the mechanical scrubbing is more effective than anything else. Perhaps washing them when SWMBO is out the house. Like I do ;)
 
I throw mine in the washing machine.

However, the other year I un-threaded all the lines back to the mast base, and threw them all in a bucket with diluted Patio Magic in, and left them overnight. They didn't go green again for a couple of years, as the algecide had got right into the rope.
 
Also recommend the washing machine. Haven't found patio magic that good on halyards (when soaked in a bucket), perhaps it does need air/drying to break down the algae and as someone did above I might have left them too long. It's marvellous on decks though.

Pretty much what I'd expect. Although the active ingredient is a surfactant, it isn't great at cleaning off grime. The idea is to let it soak into woodwork and then leave it to dry for several days (1-2 weeks would be good). It bonds weakly to wood and leaches out fairly slowly, giving long term protection after the growth has died.

I doubt you'd get similar level of long term protection with ropes, sails etc. However, leaving it to soak and then dry before rinsing several days later is probably the best approach. A detergent wash should then remove the dead material but also rinse off residual Patio Magic. I suppose you could then soak in more Patio Magic to get longer protection but I suspect it would wash out in rain.

I usually apply it to woodwork when ashore or sparingly when afloat. It is highly toxic to aquatic life and you want to minimize run-off. At least wood retains quite a lot and it doesn't simply rinse back out in the first rain shower.

Another issue is the toxic effect on household pets, especially cats. I believe cats exhibit a delayed reaction to benzalkonium chloride (high temp., ulcers, drooling and sometimes death).

So on my teak deck put it on and leave it on? What dilution do you use?
 
+1 for the washing machine. Patio Magic will have killed off the algae on your ropes but the green colour will hang around for a while.
Don’t add any detergent as it will strip the Patio Magic; you can add a glug of fabric softener though to help keep your lines soft and clean.
Daisy-chain the lines to reduce tangling, when the boss is out next.
