Drysuit Zip...

Does anyone know what to do with a 'sticky' or stiff drysuit zip?

It's on a storage bag rather than a drysuit, but I'd like to know if there is anything I can do with the zip to free it up.

Any advice greatly appreciated - thanks!!

The advice that I was given is to rub a candle on it. Don't know if it's the best solution, but it works for me!

As John said, candle wax is best, normally once its freed, Vasaline also does a similar job.

If its currently stuck, then try WD40 as it gets into gaps easier.

Candle wax is good but beeswax is better. Also you can go to Halfords and buy a "lube stick" intended for auto door seals. These work OK too.

Nip into your local dive shop, they sell beeswax for diver drysuits, only a couple of quid for a small block.

There is also a liquid for us to lube the zip before using it, comes in a bottle with a small brush on the end to apply it. Works well once you have worked it in to the zips teeth.

I'd stay away from vaseline or WD40, as they are both petroleum compounds (or at least have those compounds), which is notoriously harsh on most types of rubber.

Diving drysuits get a lube of candle wax; there are some silicone zipper lubes that will work well, but are not suggested for use on drysuits (primarily because if the stuff gets into the fabric, it'll be impossible to glue a new zipper on.)

jky

Forgot to add: sometimes cleaning the teeth with a semi-soft nylon brush (think toothbrush) helps quite a bit, too.

If the zip is crudded up from saltwater exposure then warm/hot water will help redisolve it.
Others have suggested future lubricants.

As a diver I can confirm that we use Beeswax on zips and the stuff with a brush in a bottle is called Zip Slip.

If you do use these products it is also worth, periodically, sitting down with an old toothbrush and clearing off all the old was residue and then reapplying new.

Hope this helps.

Orve.

As said by Orville, if its really bad dont force it open get some just bolied water i.e. still fairly hot and pour it along the zip. Do this with the zip shut! Then when it is still warm you get the beeswax onit really well.
