Decal liquids - use by dates?

I've just noticed a small note on a bottle of decal fixing liquid stating to use within three years. Is this really a thing? I've had all my bottles way beyond that. What is in them that perishes?

Can't answer your last question, but seems to me, use it until it stops giving you the results that it should.

I have a spot of bother believing something that’s basically vinegar could have sell-by date, especially one so short.  I often suspect this sort of thing is a scam to make you buy more before you need it.  I mean, honey is a preservative, and it’s sold with a shelf-life …

 

The alternative is that it’s not the contents that have a limited life, but the bottle.  That’s certainly the case with some bottled water - the plastic may degrade enough to become a little too porous to preserve the contents.

 

But, as Shin says - the best thing may be to use it til its stops working.  And lay in a replacement just in case.

Cheers fellas. I was struggling to believe it myself and as far as I could tell, it worked although I guess it is quite hard to tell if it is not working as well as it used to. After all, you can apply decals reasonably successfully using tap water. I also think the fact that it is only mentioned on one of three different brands bottles might also be telling.
