I also make my own laundry soap using my own liquid castile soap (grate the soap, add water & wait 'til it melts - no need to heat). I use only 1/2 cup or less per load and add a tbsp or so of washing soda. No essential oils - sunshine & fresh air smell best! Occasionally, I check the laundry detergent aisle of the grocery store. There are none that aren't 'scented'! Hate those artificial fragrances!
