I Used This To Clean my School shoes and it worked great.
* sorry for lack of pictures*
* these pictures arent mine!!*
Gather old toothbursh(it will be thrown away after) dishsoap or body wash, and a towel and a cup of water.
Then Dip The Toothbrush In The water, and add a little bit of soap to the brush, then scrub your shoes,no fabric, until the mud, dirt, or scuff marks are all off.
wipe soap away with towel.
***If Your Shoes Are white, scrub them with bleach with the tooth brush to help whiten. bleach laces if desired.
then tah-dah! hoepfully your shoes look cleaner then when you started.
