Quite often, ladies rubber rain boots will develop a white marbled film or powder on the outside. This is known as blooming. Because rubber is a natural product, in certain temperatures insoluble particles may rise to the surface. Blooming isn't very attractive but does not affect the durability of the boots.

To return the rubber boots to the original shiny finish, there are commercial sprays you can use. Or, you can use just a few drops of olive oil on a clean cloth to wipe down the boots. Work in a small area at a time, working from the top of the boot down to the sole.

Never apply the commercial spray or olive oil to the soles of the boots. No one needs a slippery boot!
