Removing oil stain: Spread fabric/garment on a flat surface with the oil based stain facing up. Sprinkle any type of baby powder or regular over the stain in a large quantity. Let the powder rest on the stain for several hours or even overnight. Brush or shake off the excess powder. You can scrape if the oil/powder residue raises up on the fabric, reapply powder and then let fabric rest again. Wash as usual. If the oil stain is still there, rubbing alcohol might remove the spot.
Removing sweat stains: Use an aspirin tablet. Crush the aspirin pill into 100 ml of warm water and wait for it to dissolve. Soak the stained part into the solution for 2 to 3 hours. Then wash as usual.
Removing blood stains: Use only cold water to dampen the stain. Rub salt into the area. Fold the stain and rub the fabric together. When the blood is nearly gone just wash the garment normally.
Removing food stains: For food stains, quickly grab some soda water and apply it over the stain. You can even use liquid soap if soda water is not available.
