Quick answer: To remove pasta sauce stains, lift off the excess, pre-treat with dish soap and white vinegar, then wash before drying. For set-in stains, soak with oxygen bleach and repeat as needed.
Pasta sauce stains are stubborn because they combine oil, tomato pigment, and sometimes protein from meat or cheese. The fastest way to beat them is to remove the solids first, then treat the stain before washing, and never put the item in the dryer until the stain is gone.
If the stain has already dried or been through a wash, you usually need a stronger second step. After pre-treating and washing, soak the item in hot water with powdered oxygen bleach overnight, then rinse and wash again. This is especially useful when the red pigment is still visible after the grease is gone.
For stubborn residue, an enzymatic stain remover or a liquid detergent with enzymes can help digest the food components. If the red color remains, oxygen bleach or hydrogen peroxide can help lift the pigment on many washable fabrics.
If the garment is silk, wool, heavily structured, or labeled dry clean only, stop before using home stain removers. Delicate fabrics and bright dyes can react badly to vinegar, peroxide, or oxygen bleach, and we can treat those safely in the shop.
Bottom line: remove the solids, pre-treat with dish soap and vinegar, wash, then inspect before drying. For older stains, add an oxygen bleach soak and repeat if needed.
