With practice and lacrosse matches all season long, by the off-season your lacrosse stick may become fairly worn looking and dirty. This is especially true for the head of your lacrosse stick -- the rounded portion of the stick, often plastic, that holds the mesh pocket. This part is essential for catching and passing the lacrosse ball. Come season's end, there are things you can do to make it look good as new.
Spray an all-purpose cleaner on a rag and wipe the lacrosse head down. This can help remove large stains and dirt.
Take a hose and fill a bucket with water.
Add soap to your bucket. You can use dish soap.
Place your lacrosse stick, head portion first, in the bucket. Place the bucket in a corner and allow the handle of your stick to rest against a wall.
Allow the stick to sit in the bucket for a day. Remove and wipe dry with a clean towel.
Avoid using a cleaning spray with bleach -- especially if your lacrosse head is not white. This can cause discoloration.
To clean the mesh portion of your lacrosse head -- for an even cleaner and newer appearance of your stick -- remove the mesh and clean it in your washer. For white mesh, use bleach. For any other colored mesh, use regular laundry detergent. Let the mesh air dry.
