Do not wash the canvas shoes directly with water!
It’s better to wash the front part and the bottom with a used toothbrush:
- Take a dry towel with a fingertip and take a little bit of water.
- Then apply some toothpaste and gently rub the front and the edge of the shoe to the heel.
- Note that when you rub the heel part it should be especially careful and gentle.
- Reclean the area with a wet cloth and it will get very clean!
