Improved rope washing ?

[Gollum]

.. Again There is a lot of conflicting stuff about pressure washers and ropes (some of which I know to be wrong) so why should I listen to the rest???? All I am saying is lets make informed choice based on fact and not old wives tales. Just telling someone it's not safe will not stop them doing it because we get told that crap all the time. I was told if I smoked dope it would lead me to become a drug addict but it didn't
Where is the evidence to prove pressure washing is not good for ropes.

So we get back to the scenario where someone conducts a proper investigation into this.

Remembering, of course, that the plural of 'anecdote' is NOT 'data'.



I think I'm agreeing with Gollum here.... :-\

No one is forcing you to listen, stopping you using pressure washers, or making it illegal.  It's a discussion, everyone can make informed choices - this is one of the places to exchange information, and opinions. Chill maan :alien:

In the same place as the good evidence that pressure washing doesn't damage them - THE FUTURE ....................................

Has anyone ever tried ultrasonic washing for rope?

A quick google came up with a few bits of kit for cleaning venetian blinds - should take a coil or plait of rope?

Trouble is, these suppliers don't seem to post prices for their kit - so it's probably too expensive for the average caver...

I just Googled ultrasonic cleaning, and it came up with one manufacturer who offers an 'Economy Range' of cleaners with prices ranging from ?110 to ?390.

You can find out if its pregnant at the same time?

T'was a serious suggestion...  really!

The usual use for ultrasonics seems to be cleaning small stuff, though - pc boards, jewellery, etc.  I suspect that's what the 'economy' kit is probably for.  You'd need something bigger (and more expensive) for a decent length of rope.

Morantz Ultrasonics (in the USA) have a range "from $289 to $31,995" including one called "the Bubba" (useful for "smaller electronics and electrical appliances")...  But the "Super Mighty One" has a 200 gallon tank and is allegedly suitable for cleaning "Stuffed Animals and Toys" - so might be OK for rope?

Thought the cleaning action might be suitable for vibrating grit out of the rope rather than washing it further in.

Any serious thoughts?

Any serious thoughts?

I don't think it'd work well for rope washing. Ultrasonic cleaning works by the cavitation of little bubbles - fantastic at helping a detergent dissolve grime in a difficult to get to recess (without having to aggressive heat it), but I can't imagine its that good at shifting macroscopic quantities of mud and grit. Also, the larger the size thing you want to clean the more powerful an ultrasonic cleaner you need, and I would think that nylon rope is pretty attenuating for the ultrasonic sound. Even the ???hundred cleaners at university only have a 3L capacity.

They are great (along with a wire brush) at cleaning up rusty metalwork with an acidic cleaning solution. Mainly I just use my little one to clean up bike parts, for which it is perfect.

I imagine the 'stuffed toy' cleaner is so you can clean without having to agitate the water or raise its temperature at all, and is quite possibly in the context of 'dry' (i.e. solvent based) cleaning. And for removing daily grime rather than glacial till.

Those thinking about pressure washing safety critical kit may wish to consider the points made in this article about potential damage to car tyres. I am afraid I have not yet found a direct link to the German research that it mentions.

And people?

Isn't that what a jucuzzi is for?

Perhaps a research project.
