If the white rubber edge of the shoe rubs against the black, you can try the following methods to clean and repair:
Instant Cleaning:Try to clean the stain as soon as it is found to avoid the stain from penetrating the rubber surface. Use a damp cloth to gently wipe to minimize stains.
Soapy water to clean:Make soapy water by mixing warm and mild soap, then use a soft brush to gently scrub the rubber edges of your shoes. Do not use strong acidic or alkaline cleaners to avoid damaging the rubber.
Toothpaste cleaning:Apply a small portion of white toothpaste to the stain and gently scrub it with a brush. The light abrasive and bleach ingredients in toothpaste may help remove stains.
Eraser:Use a white eraser to gently wipe the stain. This method works well for smaller stains, and the rubbing action of the eraser helps to remove.
Vinegar and baking soda:Mix the white vinegar and baking soda into a paste and gently wipe the rubber edges with a brush or cloth. Be careful not to use too much vinegar so as not to leave the flavor.
Professional Cleaning Products:Some professional footwear cleaning products may be effective in removing stains. Choose a cleaning product that is suitable for rubber surfaces and use as directed.
Test small areas:Before overall cleaning, it's a good idea to test on small, less visible areas of your shoes to make sure the detergent doesn't cause color fading or damage to your shoes.
Remember to clean gently so as not to damage the rubber or shoe surface. If the stain is stubborn, or if you are concerned that cleaning will affect the color of your shoes, it is best to consult the shoe brand for advice or seek a professional cleaning service before cleaning.
