Oil has varying levels of viscosity. Its true different fabrics have different level of strength.
USING HYDROGEN PEROXIDE OR (SA8 PREWASH SPRAY)
You can use one part of SA8 PREWASH SPRAY and two part of hydrogen peroxide. Mix up a small amount, and rub it in the stains. Leave it on for 30 mins. Soak for 30 mins with some of the mixture and wash.USING AMMONIA, HYDROGEN PEROXIDE AND (SA8 PREWASH SPRAY)
1 part regular ammonia, 1 part regular SA8 PREWASH SPRAY and 2 parts hydrogen peroxide. Mix it up in a large squirt bottle. All kind of stains like baby food, sports grime, blood, dirt and any oily stains.
You can pre-treat the stain when you see it, toss the item in the dirty clothes hamper and let it sit until laundry day if you want.CHALK
You can use plain white chalk it works. Even a grease stain on the back of my khaki chair the chalk worked after several times but I also added dish soap to help.EUCALYPTUS OIL
Try this onto the stain and a little rub, wash immediately it should take out those oily stains and smells so nice too. I have had pretty good results with it on some old stains. Just be careful on anything really delicate. But for cotton or polyester fabrics it works well.TALCUM POWDER
Just put talcum/baby powder and let it set over night, next day just place wash it with soap and the stains will come right off. Works almost every time.BAKING SODA AND SA8 PREWASH SPRAY
To remove any annoying spots add about a teaspoon of baking soda (soda bicarbonate) with a spray of SA8 PREWASH on each spot. I then rub the soda in it. You can let it sit over night. Wash as usual and the stain will be gone!
Above all if you only use SA8 PREWASH SPRAY on any kind of stain, it works wonders on all sort of fabrics! Just try it!
