Spray the stained areas of your sandal insoles generously with your chosen cleaner, making sure they're visibly wet but not soaked through.
Let it Soak: Allow the cleaner to penetrate the stains for a few minutes without letting it dry completely.
Scrub Away: Moisten the toothbrush under running water and vigorously scrub the stained insole areas. Clean the brush periodically under running water to avoid re-depositing dirt onto the sandals.
Wipe Clean: After a thorough scrubbing, use the old washcloth or dishcloth to wipe over the cleaned areas, removing any loosened dirt and residue.
Repeat as Necessary: Continue the process of scrubbing and wiping until the cloth no longer picks up dirt from the sandals.
Admire Your Work: Once the process is complete, you'll likely notice a significant improvement in the appearance of your sandals, making them look cleaner and more presentable.
By following these straightforward steps, you can efficiently tackle those stubborn toe, foot, and heel marks on your sandals, restoring their look and extending their life. Whether you're refreshing your favorite summer footwear or preparing pre-owned sandals for sale, this method offers a practical solution to a common problem.
