Hydrogen Peroxide - takes out blood. I learned this from my sis-in-law that used to work at a hospital. It is great!! I put my hydrogen peroxide in a spray bottle and spray it on the little(or big) spots of blood that my kids(and me) get on the clothes. Hydrogen peroxide is also a great disinfectant.
Hairspray - takes out ink. I have heard that the cheaper the hairspray the better it removes ink.
M30 - takes out grease and everything else. I found a shirt in my closet that had been laundered and had a grease spot on it that I hadn't noticed before washing it. I tried the M30 on it and it came out, even after it had been washed and dried!! I found the M30 at Dollar General for yep, $1.
