Experts say the following about stain removers.
- Treat the stain as soon as possible. If you do not have any stain removal products nearby, use cool water to keep the stain wet.
- In general, stain removers work better on non-greasy stains. Greasy and oily stains seem more impervious in testing.
- Follow the directions for each product. Some products can damage fabric if they are left on too long.
