A pair of heavy-duty rubber boots comes in handy on rainy or snowy days. Exposure to wet weather, though, can cause moisture to build up inside your boots, causing mold and mildew to develop and give off an unpleasant odor. If your rubber boots aren't smelling as fresh as you'd like, you can clean the insides with a spray of diluted vinegar. Vinegar will sanitize the boots, and its strong smell fades as it dries.
1 Crumple up several sheets of newspaper and stuff your boots with them if they're soaking wet. The newspaper absorbs moisture inside the boots. This prevents the boots from getting moldy.
2 Fill a spray bottle with a mixture of 1/2 tap water and 1/2 white vinegar. Stir or shake well to thoroughly combine the ingredients.
3 Mist the insides of both boots a few times with the water-vinegar mixture.
4 Wipe the insides of the boots with a towel to dry. Pay particular attention to the heel and toe areas. If these areas still have an odor after wiping the boots, spray and wipe them again.
5 Allow the boots to dry in a cool spot for 24 to 48 hours.
