What is the shelf life or liquid prespray?

Cleaning out the garage today I found some 7 year old Steamway Formula 0.


Still smells zesty.

Probably still as good as it ever was...if it ever was.

Mikey;

Most of the solvents will be long gone from evaporation thru the bottle.

The detergent part will still be there.

it's D-limo based.


Bottle is sort of caved in and funky feeling.

I've got a gallon of that stuff too and just about as old!
