Providing their contains have a tight seal, are not compromised by fractures or (air) leaks, and use at least a single stage fluorination of the plastic, so that it is resistant to petrochemical solvents; without this the sides will ‘collapse’, which is actually the solvents in the product escaping through the micro pores of the plastic.
Recommended storage temperatures - >35. ° - 95. °. F < All liquid products should be shaken well before use and stored in light resistant containers
a) Polymers have a shelf life of approx 3-5 years if kept in their original containers and stored at temperatures as above
b) Nanotechnology coatings - should be stored in tightly sealed containers and protected from heat and moisture. Recommended storage temperatures are 30. ° - 122. °.F Shelf life is approximately 12 months, provided the material is stored in sealed in its original containers, between 65. ° - 75. °.F.
c) Polish - technically 2 years, providing the bottle is kept closed, and the product has not separated or the solvents haven’t evaporated by leaching ( the bottle will become semi- collapsed) there should be no problem with use for three years after sale date
d) Waxes - will last almost indefinitely, provided that they are stored a sealed in their original containers and in the refrigerator or controlled environment once opened. The liquids should last 18 months if stored at normal room temperature.
e) Detailing Chemicals (Wheel cleaners, All purpose cleaners (APC) and etc) have an almost indefinite shelf life if kept in their original containers and stored at temperatures as above, see also Product separation
f) Product separation - if product emulsion separates it could be indicative of age (but not necessarily past its useful life) shake vigorously for 5-10 minutes and see if the product re- mixes.
Product shelf -life may vary from one manufacturer to another, if in doubt check with product mfg or vendor.
