Tools:

1. Toothbrush
2. Old rag I don’t care about
3. Bleach
4. Stain remover
5. Borax
6. Containers
7. Rubber gloves
8. Paper towels
9. Dish towels

I mixed bleach with water 3:1 (water:bleach), and I mixed dawn with water (no ratio used).using the toothbrush, I would wet the head with stain remover and scrub the rubber bands around the shoe to remove excess dirt and grime. Then i would rinse the toothbrush and use that to wipe away most of the stain remover. I would use a wet paper towel to get any left over remover off.

Using the old rag, I would dab it into the bleach water, and gently rub out any persistent stains while being very careful not to get the canvas or leather parts wet. I would dip the toothbrush in bleach water and use it on the toe area because of a criss-cross pattern in the rubber. I would be very careful to swipe the brush downward and away from the canvas to avoid splatter. I would also use a wet paper towel to wash away residual bleach. And finally, I would thoroughly wash the brush of any bleach.

For the canvas and leather areas, I added borax to the dawn water and then I would scrub everything using the toothbrush and borax solution. I would then rinse the shoe in water (avoiding getting water inside the shoe), and then use the clean dish rags to stuff the inside pf the toe area so it dries in shape.

It took maybe 2 hours. I also bleached my shoelaces.
