I have about 100m of old braided line about 12mm diameter that is used as the push-pull line on a running mooring for a hard dinghy in a sheltered bay.. Most winters I lift and dry out the rope but last winter was unable to do this.

Predictably a large colony of weed has taken root in the line. This winter it is ashore and I have loose coiled it over a fence in the hope that the hard winter frosts in N Scotland will get rid of the week for next season.

Any better ideas?

Thanks

Washing machine.

Soak it in a bucket of warm water and napisan for a while and then straight into your washing machine for a full wash at 40 degrees.

What you get out will be a whole lot better, if not perfect.

Beware: if you rope is old the washing machine may destroy it faster than the sea. Also, my wife hates me using the washing machine for ropes...

Dump it in a bin of water just covering the rope. Add a cup of Patio Magic. Leave for a week. Agitate and agitate for ages with a hosepipe running into the bin till the water runs clear, The weed and roots die and metamorphose into muddy sludge.

Soak it in strong PM before you re-lay it and the weed will take ages to re-colonise.

That won't please those who are concerned about the effect of PM on marine life, though quite how bad this would be I have no idea.

I've seen something for cleaning muddy caving ropes. Basically a tube lined with something like astroturf - green side inwards! Easy to improvise something like that - two scrubbing brushes cable tied together or whatever.

Or simply set up a plank at a convenient working height and scrub by hand, 3m at a time, won't take too long.

BTW, I don't like the idea of using unknown chemicals on rope.

I have a similar problem with the pick-up rope on my mooring, it is very hirsute by the Spring. At the start of the season I run the back of a knife-blade along it to get rid of much of the hairy stuff and find that once the boat is on the mooring and the pick-up rope is out of the water a combination of drying out and rainwater soaking soon sorts it out. I would guess that if you have scraped off the worst of the growth the fence treatment should do the trick.
