2. It can be used as a light stain pre-treatment
Aspirin has also been used as a simple DIY option for treating mild stains on clothing, particularly sweat marks or yellowing around collars and underarms. The usual method involves crushing a few tablets, mixing them with water to form a paste, and applying it directly to the affected area before washing.
This approach tends to work best on small, fresh stains rather than older or deeply set ones. It is often treated as a quick fix when you do not have a proper stain remover available. Letting the paste sit for a short period before rinsing and washing can sometimes improve the result.
However, it is important to test this on a small area first, especially with delicate fabrics. While it can help in certain situations, it is not as reliable as purpose-made laundry products, and stronger stains may still require a more targeted solution.
