How to clean sandals with cork footbeds (Birkenstock type)? All the tricks for washing them without making them harden

Sandals with a cork footbed are very comfortable for the summer season and also suitable for those who walk a lot or spend a good part of the day on their feet. They are practical, they match almost every outfitsthey are very easy to put on because very often they are clogs without closures and straps.

Cork, comfortable and breathable, is a very delicate material that must be protected so that it retains its properties (first and foremost, its softness). First of all, it blackens quickly, and this can affect the original beauty of the sandal.

Furthermore, since it is a very absorbent material, it can quickly turn into a deposit of bacteria, sweat and bad odors: our feet, especially in summer, sweat a lot and sweat and dead cells are deposited on the sandals, creating an environment that is anything but healthy.

Finally, if exposed to heat sources or simply to sunlight, cork will tend to dry out, losing its softness: this increases the risk of cracks within the material which can make our sandals uncomfortable, if not unusable.

Prevention

In addition to periodic cleaning, it is useful to take some precautions to prevent deterioration of the cork. A useful tip is to alternate the use of sandals with other footwear, avoiding wearing them every day for long periods: in this way the material has time to “breathe” and dry completely between one use and another. It is also good practice not to store wet sandals in closed boxes or poorly ventilated cupboards, as trapped moisture encourages the proliferation of bacteria and mold.

How to clean cork sandals

Luckily, cleaning cork sandals is a rather simple operation, which requires the use of ingredients that we can easily find in our kitchen: bicarbonate of soda, lemon juice, olive oil, warm water. Let’s see how to do it.

If our sandals are blackened, just mix a few tablespoons of bicarbonate of soda with a few drops of lemon juice to create a sort of paste. We then spread this paste over the entire surface of the cork insole and leave it to act for an hour before rinsing with hot water: the whitening action of bicarbonate and lemon will eliminate stains and marks.

Another effective natural remedy, especially for those suffering from excessive sweating, is talcum powder or rice starch. Simply sprinkle a small amount on the footbed in the evening, after use, and leave it to act until the following morning: these products absorb residual humidity and help keep the cork dry, reducing the risk of bad odors and the formation of dark stains due to sweat.

If, however, the cork of the footbed has now hardened, we can “nourish” it with a little olive oil. In this case, we pour a few drops of oil into the center of the footbed and massage the entire surface well with the hand, then leave it to act overnight. Before wearing your sandals again, remember to clean them with a damp cloth to remove excess oil.

Finally, if the sandals have now taken on a bad odor (due to colonies of bacteria and accumulated foot sweat) we can act with pure bicarbonate, given its powerful anti-odor action. All we have to do is sprinkle the footbed with baking soda powder, leave it to act for a few hours and then rub vigorously with a soft cloth to remove the dust.

For this purpose, if we have it at home, we can also use white clay: this product, in fact, also absorbs toxins and neutralizes bad odors, sanitizing our sandals. It is used in the same way as bicarbonate.

How to dry cork sandals after washing

A final aspect not to be underestimated concerns drying after washing: cork should never be exposed directly to the sun or to heat sources such as radiators or hairdryers, because it would risk drying out and cracking quickly. The best choice is to leave the sandals to dry in the shade, in a well-ventilated place, perhaps temporarily padding the footbed area with absorbent paper to speed up drying without compromising their softness.
