Does Disc Doctor Miracle Record Cleaner go bad?

Have some of this fluid on the shelf for about 4 years. Still safe and effective?
Mine never seemed to go bad.
Thanks for your response Goliverjr. I guess I will give it a try
I've used Disc Doctor fluids for years : Never has the mixed product or concentrate of Disc Doctor fluids grown mold ,or otherwise been un-useable. That can not be said in regard to some record cleaning fluids that were mixed with H2O from Europe & UK that appear to have a limited shelf life. Please review older postings on AG for details.
