The remaining unused lubricating grease can be stored for future use. The surface of the grease should be left smooth (without depressions) by smoothing it with a clean implement such as a spatula or putty knife. The container should then be gently banged on a hard surface to remove any entrained air bubbles and re-smoothed. This is to minimize the separation of oil from the grease during storage. The lid or cover should be placed on the container and secured as well as possible, and the container should be stored indoors out of direct sunlight and away from any heat sources.
