I have decided to clean out my garage of stuff that is old or outdated. so now I am wondering just how long the shelf life is on some of this stuff. ALL of it is at least 8 years old. Motor oil I am tossing since my web research has shown that 5 years is pretty much the max recommended by the companies. But what about things like:



quick detailer

spray wax

carnauba wax

engine degreasers

Rain-X



None of this has a "use by" date or any recommendations regarding shelf life. so to you that do detailing ... how long do you keep this sh*t before refreshing it?

 

I'd probably just toss it, personally.

 

I generally toss all mine out if they are a year or more older.
