Oh well, there’s no perfect answer to this question but we can definitely give you a little feedback and/or advice… we did try to wash our wetty in our washing machine and pretty much like everything in life there’s an easy way to avoid a catastroph: dont go too far or too extreme! Dont wash your brand new suit with a full on crazy 90°C washing cycle, that will of course damage your beloved piece of neoprene!
Most manufacturers will tell you not to wash your suit in a washing machine but we did it anyways, at 30°C with a gentle cycle, no dry-tumbling, no extra dryer of course, just a short and simple washing cycle (same as for a fragile 100% wool jumper for example), this is it. We used a little bit of washing machine liquid or powder but way less then the normal dose (maybe just a 1/4 of a dose). The result was great, the suit we washed was fully stretch again (with all the salt that left the neoprene material and the seams it makes the suit as stretch as it was new), it smelt good again and was doing fine (nothing delaminated or damaged).
When and why would you wash your suit in your washing machine you’re gonna ask? Well, we reckon it’s a good way to give your 1 or 2 years old suit a second life, it cleans it from salt, dirt, pee etc. and makes it feel comfy and stretch again. It works way better than the do it yourself hand-wash products available on the market and it’s cool if you’re a bit lazy. Do not do it on a brand new suit under warranty of course, dont be stupid, only do it on a suit that you dont really care about anymore or a suit you dont count on as your main suit for the coming winter. Do it on your second suit for example if you have two suits and this should definitely help keeping your old suit in a good shape, nice and clean.
Disclaimer: We are not responsible for anything if you kill your suit trying to wash it but there aren’t high risks of damaging a suit if you only wash it with a gentle and quick washing cycle without a dryer cycle.
