Directions:
Spray liberally onto stain and wash according to manufacturers directions. For old or tough stains, spray and leave on over night. May need to be treated and washed twice to completely remove an old stain.
For older stains:
Make sure the fabric you are cleaning is washable – either by spot cleaning with a brush and water – or machine/hand washable.
Spray the fabric and let it sit for 30 minutes , then machine wash or scrub with water and a fabric brush. You may have to do this 2-3 times depending on how old and set it the stain is. But with patience it should eventually come out entirely or be a lot less noticeable.
