Earlier this year I made some laundry soap using Fels Naptha. You can read about it and link to the recipe here. The recipe worked great, but I thought the smell and look of it could be improved. :)
I just finished making my second batch substituting Dr. Bronner's bar castile soap in a lavender scent instead of the Fels Naptha. I like this version much better. I noticed no difference in the cleaning quality nor consistency, but it looks nicer (not a snot color!) and smells nicer. It was slightly sudsier in the making process, but didn't leave a residue in the washing cycle. I can't say I noticed a scent on the clothing when it was washed and dried, but I might experiment later with adding some lavender essential oil. For now, I just dab some on a washcloth and throw it in the dryer with the wet clothes.
I just wanted to provide an update for those of you who are in the process of cutting costs, chemicals, or both. I'll continue to update as I experiment with more variations.
