Frozen zipper’s on canvas

[Dand1]

I’m trying to remove all canvas so I can have all plastic windows replaced over the winter. Most of the zipper,s are completely frozen and won’t budge. I have tried penetrating spray and let it sit overnight, still no movement. Any suggestions on getting these zippers to move would be greatly appreciated

It might be a little difficult but I run very hot water to dissolve the salt/sodium crusted on it and a wire brush if it’s real crusty I’ve done this multiple times and have worked a very high percentage of the time.
the other less success is salt away or vinegar
Once it’s free Rub the zippers with candlewax works great to get the zippers work properly again .

If you are having the plastic replaced, might as well have those old frozen zippers replaced too.
So....don't stress over it and take a box cutter to the fabric alongside the zippers and cut them off.

Plastic zippers can often be freed up but metal ones may not since the corrosion can 'weld' the teeth together. Use a penetrant on metal and after soaking use a pliers to try to get the slide to move.Try forcing back and forth.
Be careful with penetrants on plastic zippers. Some chemicals can dissolve the plastic

I bought new plastic zippers from SailRite and replace the old ones frozen ones. Then I keep them lubed with silicon grease.

I use a zipper lube product that you can find in a lot of marine stores. I think it is StarBrite snap and zipper lube.

I believe that GW recommends applying petroleum jelly to the zippers annually. Coincidentally, I applied it to my zippers and snaps today.

I think that might just be the answer. The front ones have never been off or open. Bought the boat new in 2012 And all my boating is offshore so there is plenty of salt. Thanks for advise

Brush repeatedly over the course of an hour or so with CLR.

Penetrating spray? I hope it’s not something like WD40? Chemicals like that can actually melt the plastic effectively welding plastic parts together.
Silicon spray or just water is a better Choice while patient working it loose. Then bees wax on the zippers to keep them moving and free.

Yup - just cut 'em out. Sometimes the simplest solution is not always the first one we think of. I like beeswax, as well - as opposed to some type of lube since beeswax is dry and won't attract/collect dust/debris/etc.

I've had good results with silicone spray. no guarantees if they've been frozen for very long.

do you mean cut above zipper

do you mean cut above zipper

 

[glacierbaze]

Cut the fabric zipper tape, right along side the zipper teeth. Do not cut the canvas. Another option is to just wedge an awl into the large end of the zipper slide, and force it open enough to remove it from the teeth. Then you should be able to pull the teeth apart.Don't stab yourself!

We’re exactly do you mean when you say cut the zipper tape? Would that be above or below the zipper. That would leave a small strip in the track of the window to remove also to remove , correct?

 

[seasick]

If your canvas and vinyl are in good shapes other than hazing bad zippers, I would recommend having a canvass shop replace the zippers, especially if they are large. In addition to needing a fairly powerful walking foot sewing machine, you also need the correct zipper feet for the machine.
This is a link to a typical zipper type for your application if you are going to try replacing the zippers yourself.

Along side the teeth, not above or below. You only need to cut one side of each zipper to separate it. The zipper should extend several inches above the track, rather than being in it at the top. Once you separate the pieces, they should slide out of the track. You can take a pair of snips, and cut the box, where the two ends are joined, off the top end, pull the teeth apart, and just cut around the slide at the bottom.
