Step 1 - Rinsing. Especially for larger neoprene-based items, you should be rinsing for at least three or four minutes straight after every use. Try to rinse using clean, fresh water applied in a directed spray. A shower head with a removable handle will work for smaller items, so you can direct the spray in the tub.
You can use a spray bottle to apply stain removal directly to the collar, or you can soak your shirt in a solution of water and OxiClean powder. NOTE: Do NOT put your shirt in the dryer unless the stain is completely removed.
