THE SHORT ANSWER
Blot up the excess with a clean white cloth. Do not rub.
Why white cotton changes the answer
White cotton is usually launderable, but the care symbol still controls wash temperature and which products may be used. White fabric does not automatically tolerate chlorine bleach. Tea tannins may leave visible colouring as liquid dries.
A careful step-by-step approach
- 1
Cool-water treatment
If washable, flush the stain gently from the back with cool running water, or soak briefly in cool water if the label permits.
- 2
Pre-treat the mark
Apply a little liquid laundry detergent or a stain remover labelled for the fabric. Follow its directions and rinse thoroughly.
- 3
Launder, then inspect
Wash using the garment’s care label and the cleaner’s instructions. For persistent marks, a labelled colour-safe oxygen laundry product may be an option only if the garment care instructions permit it; never assume any bleach is safe. Check the mark before drying; repeat a compatible treatment if needed. Air-dry until it is gone.
What not to do
- Do not tumble-dry or iron before checking that the stain is gone.
- Do not mix bleach with vinegar, ammonia or other cleaning products.
- Do not skip a hidden-area colourfastness test when using a cleaner.
What if it already dried?
A cool-water rinse and fabric-safe pretreatment are good first choices on washable garments. A dried stain can require different handling and may be less responsive to treatment. Our tool generates a separate plan that accounts for timing while preserving the same material safeguards.
