Are there any really effective pre-wash stain treaments like Spray & Wash that are natural? I have been using a combination of enzyme stain remover and Dr. Bronner's soap when necessary before washing, but I feel like all my clothes have stains on them (i.e. oil spots, tea splashes etc.). WHen my mom uses Spray & Wash, everything comes out. But I want to find a natural alternative...Thank you mamas in advance for your suggestions, routines, etc.
