Get your fresh mushrooms, a paper towel or clean cloth, a small brush, a cutting board,and a sharp knife.
Check for visible dirt, blemishes, and remove any spoiled or moldy pieces.
Hold your mushroom in one hand and gently brush off dirt with a small brush.
Cut off the end of the stem and remove any tough or woody parts.
Briefly rinse under cold water if extremely dirty, and pat dry immediately. Use a salad spinner for excess moisture if needed.
Inspect for missed spots and pat your mushrooms quickly with a paper towel.
If not using immediately, store your cleaned mushrooms in a paper bag in your fridge's crisper drawer.
