There are four types of brushes useful to get dirt, dust and lint off your jacket:
1) A roller with sticky sheets, best for getting pet hairs and obvious lent off your clothes. It's a good type for keeping in your car or office desk for emergency use.
2) A wire bristle brush, usually brass, can be used for deeper cleaning.
3) Nylon or other bristles are also effective for deep cleaning.
4) A raised fabric brush that creates static electricity to pick up lent. You brush one way to clean clothes and the opposite way to clean the brush. Sometimes these come in combination with the Nylon brush.
