One truth about removing grass stains from clothes is that it can be challenging. This is because grass stain is basically a dye. Dyes are by definition hard to get out of fabric, and the grass dye is made largely from protein and stable pigments. On top of this, grass stains are very often ground in with soil.
This leads to the second truth about removing grass stains, which is it must be attempted as soon as possible before the stain has a chance to set. The third truth about removing grass stains is that it can be done, and can even be done without leaving a hint of a ghost behind.
First, there are cleansers that are never used to remove grass stains. They are degreasers or anything alkaline. These chemicals not only don’t remove grass stains but cause them to set. Also, if the garment has a dry clean only label, it needs to be taken to the dry cleaners right away.
Acetone based cleaners should also not be used on fabrics with acetate, because they can actually cause the fabric to melt.
The best cleansers for removing grass stains are those that contain enzymes, for it is the job of enzymes to break up proteins. A cleanser that has bleach along with the enzymes is even better. Make sure the fabric can tolerate chlorine bleach first.
First, pour the cleanser into the grass stain, and rub it in. Let it sit for as long as 15 but no less than 10 minutes, then wash the fabric as usual. If there is a ghost, repeat until the stain is completely gone.
Some people pre-treat the stain with a solution of warm water and vinegar or warm water and rubbing alcohol.
Another method that uses rubbing alcohol is to use a sponge to soak the stain with alcohol, hang it up outside to let it dry in the air, and then rinse it with cool water. Then, the detergent with bleach and enzymes are rubbed into the stain, it is rinsed again, air-dried again and then tossed into the washing machine.
There are other products specifically made to remove grass stains. Again, they should be placed on the stain, rubbed in, allowed to sit for about 15 minutes and then washed according to the label on the garment.
There are other ways to get out grass stains that are a bit off the beaten path. Here are a couple:
Karo Syrup or Molasses
Place a few drops of karo syrup or molasses on the stain and rub in vigorously. Let it sit for a while, and then wash.
Believe it or not, banana oil attacks chlorophyll, the stuff that makes grass stains green. Place it on the stain, rub in and rinse, this time with hot water. If there’s a ghost, mix two tablespoons each of ammonia and detergent with a cup of cold water. Rub this gently into the stain. Banana oil can be found on-line and in health food stores.
