If you have waxes/polishes/glazes/compounds, you'll want to store them at ABOVE FREEZING, so if you don't have an area outdoors that satisfies that, you should keep them indoors. THese products have ingredients that will separate out when they freeze and it usually ruins the product because it doesn't mix back in right upon thawing. A lot of other cleaners and solvents aren't picky about it as much, if at all.
