You CAN put ropes in water. It is usually ok if you are careful.
We were ok in water with many of my models! We shot on the beach, in the pool, in a cenote, in the bathtubs, and no models were hurt. Plus, I haven't ruined even one rope!
As I said, the rope gets tighter, but let’s look a little deeper.
Putting tied-up models in water is even more dangerous, than ropes in general. You need SAFETY scissors at all times, but especially when ropes are wet. What if you made a little mistake and rope affects nerve or breathing? well, things can happen to anyone, so make sure you're prepared!
If we are talking about natural fibre rope, water impacts the fibre, and it can lead to weak and damaged rope.
NOTE that rope that got wet should never be used for suspension in the future, as the fibres expand and loosen from their original weave.
We had a situation with red rope in the pool and when Model got out of the pool, it looked like she was bleeding from every possible place on her body. Yes, that was really leaky red rope. So, another piece of advice here: before tying someone underwater, please make a little piece of your rope wet and check if that tiny piece is very leaky. So you know what to expect!
Even munter hitches sometimes are hard to untie with wet rope, so plan your knots/twists ahead.
I take a bucket of water and put my ropes in it for about 2 min, washing them all together. Then change the water, do it again. Then change the water and add a bit of oils in it so rope gets a bit of them on it when I pull it out. I slowly pull ropes out of the water and then stretch them to get ready for drying. I put them under the sun for about 30 min, but then put them inside and wait ... I`d say about 2 days for it to fully dry. I live in Mexico at the moment, so with this humidity...maybe 3 days.
If you need to wash your ropes, here is a video with advice!
