Does Optimum No Rinse have an expiry date?

Hi all.

I've been using ONR for a year now and love it. I'm about to buy a 32 oz bottle but for a dozen more dollars I can get a gallon (silly, I know, but I'm in Canada and I gotta buy online...). However I'm worried I might have too much and it'll just sit there and I'll waste it, or damage my paint if it's "expired"/lost its lubricity and I'm not aware of it.

Has anybody kept ONR for a couple years?

Thanks.

Just close it up tight it will be just fine

I've had a large bottle (1 gallon?) for over 2 years now and it works just the same, every mix. I also leave mine in my hot FL garage year round.

Since you'll have so much, use it for everything: Rinseless wash, quick detailer, clay lube, water softener, hardwood floor cleaner, etc

I have 2 gallons of it (one ONR&S and one ONR&W) purchased them in 2013 and they are still good.

Thanks guys, I'll go with the gallon and save some money on the long run :)
