You don't need a special stain remover or laundry pre-treater to banish ring around the collar. Instead, an item that you surely have lurking in your shower will take care of business!
Whether it's on work shirts or Sunday best, staining around the collar can be easily vanquished with a touch of something you're pretty much guaranteed to have in the house — shampoo. Just pour a little shampoo onto the collar, rub the collar together to work the shampoo in well, allow it to soak for about 15 to 30 minutes, then rinse thoroughly. Follow-up by laundering as usual. Although any shampoo will likely do the trick, some experts recommend using a brand that's formulated specifically for oily hair because it is designed to break down body oils, grit and other stuff that transfers from skin to collar [source: Taylor].
