All car acre products are negatively impacted by wide temperature fluctuations and extremes of high or low temperatures. As far as wax storage is concerned standard room temperature will suffice; a refrigerator provides a stable temperature / humidity, which equates to a longer shelf life to the products.
Water-based car care products should not be stored at temperatures below > 35.OF (wax 45.OF) if they freeze they may become unstable and therefore unusable, ideal storage temperature range- 50- 7.OF with an average humidity range. Most car care products have a ‘useful life’ of approximately 2-3 years provided they are stored as above.
Keep containers tightly closed and ensure they are not compromised (fractured or leaking seals) store in a dry, cool and well-ventilated place. Keep away from direct sunlight. Do not allow to freeze. Do not store at temperature extremes (below 40 – over 80.OF +) as heat will destabilise emulsified products (wax, polymer sealants, polishes, etc) and avoid extreme temperature swings as the chemicals will become unstable, which will create problems with the performance of the product. Some separate out; others lose their effectiveness if they are heated past a certain point. Most car care products (including Polymers) will separate and may become unusable after being subjected to freezing temperatures
The chemical composition of waxes rarely ever change regardless of what form it is in, whether it is melted to a semi-liquid or remains as a semi-solid. Temperature has little to no effect as far as inhibiting the shelf life of wax, a cool temperatures and constant humidity will slow the evaporation of solvents from the wax, thus keeping the wax softer and easier to use over a longer period of time.
