Barbecue sauce.
Soak and rinse with club soda, then wash in warm water. Repeat the process if necessary. Check carefully after washing; if you put something that’s still stained in the dryer, the heat will set the stain forever.

Grape juice or red wine.
Treat stains immediately with club soda, soaking and rubbing gently. Wash as soon as you can.

Lipstick.
Loosen stain with a nonflammable dry-cleaning solvent, then rub with liquid detergent until stain outline is gone. Wash in hottest water safe for fabric.

Perspiration.
Sponge fresh stains with ammonia, old stains with vinegar. Presoak in cold or warm water, then rinse and wash in hottest water safe for fabric, adding bleach if fabric is yellowed. If stain still remains, dampen and sprinkle with meat tenderizer. Let stand one hour, brush off tenderizer and wash. Sponge any garments that have a persistent odor with colorless mouthwash.
