The sea is an essentially beneficial place, but not really for those who swim in it. And they might be folks who needs things like the wetsuit cleaner which will be a special kind of shampoo made for the neoprene material the suit is often made with. This special fabric is not impermeable, and needs care like all other fabrics.
The special process is not really complicated when you think about it. You may do research on how to clean up your wet or dry suit you use for water sports and other related activities. These could involve the immersion of your unit and yourself in hours of the saline or salt solution called seawater, which often features other elements in it.
While it is one of the best cleaners all around there are lots of bacteria that thrive in this kind of water. And salt itself can damage your unit, because it is a scouring agent. You simply have to immediately address the cleaning process after taking off the suit, by separating it from other clothing items.
Then you should have some container prepared with some baking soda and lukewarm water. Or you could immediately use the shampoo or cleaning agent by mixing it in the water. This will start soaking of salt and other elements that your suit has been in contact with. Also, the longer this soaking lasts, the more chances or totally eliminating salt or deposits of it.
You could say that this is a responsibility, especially when you make your living as a diver, or are a master licensed expert. This will make your equipment work better and last longer. And in any case, you might have more things that you could take care of, but ignoring the suit is something you do at the risk of not having one.
The neoprene is simply a fabric that is more specialized in term of buoyancy and movement in the water. This is soaked through but it may have actually less water molecules inside it. But then these could be hard to take out, much harder than when you are addressing some popular or common material like cotton.
This will be a thing that should interest those who have some chemical knowledge. But in any case, the availability and use of the cleaning product is there to address all your concerns. This is intensive enough that you do not need to do the process twice, and it should be good enough.
That is for the more common activities that do not involve any chemical or oil spill when working the sea. Some divers have specially designed clothing when they do some vital or emergency stuff that could also mean contamination. Which is actually more complex and could involve infection and other conditions.
The neoprene is a special item in a range of products that are conducive to all activities in saltwater. You need to know how your suit works and how it should be maintained or kept. This will be something that is going to be important when you value what you do or have work related to it.
