3
Rinse and dry

Rinse thoroughly. Turn upside down to drain. Dry completely before storing.

2 min + drying
Never store rubber boots while damp inside. This causes mold and degradation.
4
Treat bloom (if present)

White chalky film on rubber boots is called bloom. It is natural rubber oils migrating to the surface. Rub a small amount of olive oil over the surface with a cloth to restore the shine and remove bloom.

Silicone spray also works and provides a water-repellent finish.
🚫 What NOT to Do
  • Do not store rubber boots in direct sunlight (UV degrades rubber)
  • Do not store near heat sources
  • Do not fold rubber boots (causes cracking at the fold)
💡 Pro Tips from The Freak
  • Store rubber boots standing upright, stuffed with newspaper to maintain shape.
  • Sprinkle baking soda inside after wearing to absorb moisture and odor.
  • If the inside smells: wipe with a cloth dampened with rubbing alcohol.
