Why should you clean your wetsuit after every open water swim?

In most triathlons, the swim takes place outside, either in a lake, river or the sea. Training in a similar environment makes sure you are fully ready to take on the first leg of the race and gives you a chance to test out all of the race kit, especially your wetsuit. Your wetsuit is likely to be the most expensive item of equipment you have for swimming, and looking after it is crucial. In this article, Coach Denise looks at why it should be cleaned and how to do it.

As the water is starting to get warmer and more of us are getting outside to swim, one important question is, why should I clean my wetsuit? After all, I’m swimming in water, so surely it’s clean enough already.

There are a few reasons to clean your suit regularly:

  • The water you swim in may not actually be that clean. Any sand, algae, water debris etc., will get into the inside and outside of the suit. Putting on a dirty suit is just not nice.

  • Suppose you swim in different bodies of water. In that case, it is possible to transfer microorganisms from one to the other, so cleaning the suit, and all other swim accessories, after use is vital for biosecurity.

  • If you use the traditional method (and yes, I mean peeing in it) to warm up the water in the suit, then cleaning the inside is especially important

  • When you clean the suit, you can look at it and check for any damage or small holes so they can be repaired before they become a problem.

So now I’ve convinced you that you need to clean your suit, how is it done? The good news is that it’s really not that difficult.

Simply rinse the suit in freshwater as soon as possible after your swim. Dipping it in the water you got out of sounds sensible but doesn’t address the biosecurity concern and may just put in more sand or silt from the water. Use tap water either lakeside, seaside or at home.

Hang the suit up, inside out, using a broad-shouldered plastic coat hanger to prevent any damage at the shoulders, or better yet, fold it at the waist.

Allow to drip, then fully dry in a warm area, out of direct sunlight. Put through to the right way out once the inside is dry and hang up again if the outside is still wet.

Remove it from the hanger once the suit is fully dry and roll it up for storage.

It’s as easy as that – one clean and dry suit, ready for use.
