Let's face it. Stains on clothing are an on-going challenge. No shirt is safe from a ketchup bottle with an attitude and no pants can run from the little boy who slides into home plate. Charlie's Soap Laundry Pre-Spray is a cost effective and environmentally safe way to deal with most stains. Like all Charlie's products, it goes back to nature quickly. Just watch it work Apply the Pre-Spray to the stain, directly on the fabric as soon as you notice it. Rub the Pre-Spray into the stain and let it sit for a bit - maybe 30 minutes. Don't be afraid to let it dry. Charlie's Soap Laundry Pre-Spray was designed to gently remove stains , not blast them off. The Laundry Pre-Spray will separate the stain from the fabric. The treated area will look like the stain is spreading - and that means that it will come out in the wash. Re-wet the stain with Pre-Spray just before you pop it into the wash. Feel free to repeat the process if necessary. Our Laundry Pre-Spray will not damage any fabric. (It might be a good idea to test for color fastness and follow your garment's care instructions, though.) - See more at: http: - - www.charliesoap.com - laundry_prespray.html#sthash.aTQPQstA.dpuf.
