Deformation
Care should be taken that rubber products are stored in the unstressed state, i.e. without tension, compression, or any other deformation since stress favours not only compression set but also crack formation. Contact between rubber products of various compositions is to be avoided. This applies especially to rubber products of differing colours. Rubber products should remain in the store for the shortest possible period. For long-term storage, care should be taken that newly arriving products are stored separately from those already in store.

Cleaning and Maintenance
Cleaning of rubber products can be carried out using soap and warm water. The cleaned articles are to be dried at room temperature. After long storage (6 to 8 months), the products can be cleaned with a 1.5% solution of sodium bicarbonate. Residues of the cleaning solution should be rinsed off with water. Effective and especially gentle cleaning agents are recommended by the manufacturer.
