I've found that the Beal rope brush works pretty well if you put some pure soap flakes in the bath with some warm water. If you do that and there isn't a line of grey scum around the sides of the bath either your rope's really clean or you're doing it wrong!
I find the best way to get old-school soap flakes to dissolve is to stir them into a jug of boiling water, then chuck the solution in. (When using the washing machine, the hot soapy water just goes straight into the drum before loading the washing in.)
+1 for the rope brush, if it's the coiled spring type let it spread a little so it is nice and tight on the rope, then get a friend to help haul the rope through and it will remove loads of ingrained dirt. It's a proper workout though!
This might sound silly, but you've already given it a bath so just be careful who you're throwing stones at. But.....
if you have access to a field with some decent longish grass take it for a walk when there's a lot of dew on the ground or it's been raining. As long as the ground is not muddy, the grass scrubs it all up quite well. Snow if even better, but it's the wrong time of year. Not good if the field you have in mind is frequented by geese, cows or dog walkers.
In reply to Elsier Take it to the laundrette.... Method.... 1egg cup full of non bio washing liquid plus bath towels put on wool/silk wash and bobs your uncle.Or tread in the bath till skin falls of feet.
Get a dark coloured rope next time so you don't notice the dirt?
Just kidding. Ours got filthy in Kalymnos too. It's just a 70m but I chucked it in the machine (looping first so it didn't tangle) either with soap flakes or Nikwax tech wash (pretty sure it was Nikwax) and it came out pretty much clean. I did run it through the rope brush first quickly the rope was dry. 70m is only about 500g lighter than 80m so hopefully the washing machine will be ok. If you're worried about the weight then a trip to laundrette might be a plan.
I washed my 80m 9.5mm rope in the washing machine with no problems
You can avoid the difficulties with dissolving soap flakes by using Dri-Pak liquid laundry soap. This is also good for washing waterproofs and softshells.
Soak it in water, then bung it in the washing machine small amount of washing powder, no need to loop it or owt else, it'll get a bit tangled but no more than on a day out, loop over the banister to dry.
Ours also got massively dirty on its first use last year in Sardinia. Have washed it several times now (actually Brian did...) Somebody at a crag said to me that it might actually be the carabiner on the Click-up doing it rather than actual dirt. I am starting to wonder if he is right?
