To clean the transparent case, bleach in the form of powder, liquid, or spray is suitable.
Dilute the detergent in warm water in a ratio of 1:10, apply the solution to a sponge or cotton pad and treat the surface of the case.
For severe stains, use a toothbrush.
One of the safest ways to remove yellowness from a case is to use soap.
Grate the soap on a fine grater and dilute it in warm water.
Place the cover in the soapy solution and leave for 60-80 minutes.
Then wipe with a soft cloth or sponge and rinse under warm running water.
Add a little toothpaste, a few drops of dish soap, a teaspoon of salt and ½ cup of 9% vinegar.
Place the case in water for 15–20 minutes.
Then rinse thoroughly with a toothbrush.
Rinse the case under running water and dry with a paper towel.
The cleaning process is almost identical.
First, you need to rinse the case and dry it, then check the reaction of the silicone to alcohol in an inconspicuous area, and then remove the stains with a cotton swab or disk soaked in alcohol.
In addition, after cleaning the case, you need to wash it again in soapy and running water and dry it.
