How long will it last in the bottle?

I have about 3/4 of a bottle of P21s Paintwork Cleanser that I bought several years ago. I've kept it in a cool, dark cabinet but wonder if it's still good in terms of its effectiveness.

I suppose I could try it on one body panel to see if it still works its magic, but just wondering if anybody here has an idea about whether or not this product can expire in the bottle.
