Quick Detailer - does it go off?

[topless360]

I've got a bottle of the stuff sitting in the garage, I think it's been there for around 5 years or so. Still plenty left in the bottle, but is it ok to use on my P&J? Or will it have lost some of its lubricating properties?

Should be fine as long as its not been exposed to the sun or frozen.
