Polish is best kept upright in a cool place away from sunlight and heat, which helps limit changes in its quality. Wiping the bottle neck before closing helps prevent the cap from sticking shut. If it thickens, add a little thinner and roll the bottle to mix, which brings back a smoother feel.

Recommended for: People who want to keep using favorite polish as long as possible or worry about it thickening.
