Part 2: Which method fits

Never rub the stain vigorously; it can damage the cotton fibers.
Avoid hot water, as it can set the stain further.
Do not use bleach, hydrogen peroxide, vinegar, or ammonia on cotton without testing, as they can cause discoloration.
Don't dry the shirt until the stain is completely removed; heat will set it.

Fresh vs. Dried Stains

For fresh coffee stains, blot immediately and rinse with cool water, then treat with dish soap. For dried stains, rehydrate with cool water first, then use the dish soap or baking soda method. Baking soda is particularly effective on dried stains because it gently lifts the particles.

Surface Warnings

Cotton is durable but can be sensitive to harsh chemicals. Always test a hidden area first. If the shirt is delicate or has special finishes, consider professional cleaning.

Alternatives

If dish soap and baking soda don't work, try a commercial oxygen-based stain remover, following the product instructions. Always test on a hidden area first.

Repeat or Stop

You can safely repeat the dish soap and baking soda treatments up to three times. If the stain hasn't improved after three attempts, stop and consult a professional dry cleaner to avoid damaging the fabric.
