Sneakers and fabric shoes can all need a little cleaning from time to time, and if you do, you'll have shoes that look nice for a long time. You can either use Lemon Soap or Lemon Foam to remove stains, and Lemon wash if you are only going to wash them in the washing machine.

Shoes that can be washed in the machine are rubbed with lemon soap and water on all dirty surfaces before being washed at 40 degrees with Lemon wash. If they are very dirty, you can rub them with Lemon Soap and leave them in the soapy water for a while before washing them in the machine.

If you are going to clean sneakers without washing them afterwards , use Lemon Foam. Rub the foam well over the entire shoe and rinse or wipe off immediately with a wet cloth. Check the video below how easy it is.
