How to make the white edge of shoes white

first, glue the top of the white shoe edge with transparent tape to avoid getting wet and dirty when brushing the shoe edge.

put some detergent in the bowl, mix it with water, dip it in water with a small shoe brush or toothbrush, brush the edges of the shoes first, then scrub them with water and clean them with a cloth.

Squeeze the toothpaste we usually use to brush our teeth on the edge of our shoes, just squeeze a proper amount. I squeezed a little too much.

Dip your toothbrush in water and brush the edges of your shoes repeatedly. Brush the dirty parts a few times.

after brushing, immediately wipe off the toothpaste with a dry rag, and then wet the rag and wipe it again.

clean the edges of the shoes with soft paper, and then tear off the transparent adhesive tape.
