To use the EZ Apron, simply put it on by slipping it over your head. The memory waistband will adjust to your waist automatically. When you're done using it, just pull it off easily. As for maintenance, you can machine - wash it on a gentle cycle. Avoid using harsh detergents as they may damage the fabric. Store it in a dry place when not in use. Keep in mind that while it's one - size - fits - most, it may not fit extremely large or small body types perfectly.
