you make this whitening product? Pour hot water into a basin, into which you pour 5 aspirin tablets of 325 milligrams. Once these are well dissolved, you can immerse the garments.

They are left to soak for about 8 hours, after which they should be wrung out and placed in the washing machine, following the program as we usually do.
A quicker alternative is to add 5 aspirin tablets to your usual wash, although the result is less “dazzling” than the first one, it is still satisfactory.
