Fill a sink with lukewarm water, then add a few drops of the glove wash and stir the water around with the scrub brush.
Put the gloves in the water/glove wash mixture, and wash the outside of them. Use the scrub brush to work the dirt out of the gloves.
Remove the gloves from the water and turn them inside out, then put them back in the water and scrub them with the brush again.
Rinse the gloves off in clean water once they are cleaned to your satisfaction.
