How should I store Yes^® products?

Various things can cause the life of any product to be shortened, extreme temperatures (leaving it on a sunny window sill) or the addition of bacteria or fungi when removing the lid/cap.

Yes products, as they are made from natural ingredients, are more sensitive to harsh conditions than their synthetic chemical cousins (actually more distant than cousins).  Do not leave them on a sunny window sill, keep them at room temperature, no freezing or boiling, keep the lid on when you are not using them.  They are not too sensitive, so you don’t have to turn out the light although they do like a little candle light.
