I started making homemade laundry butter for personal use and like it so well that I hope you do too! Laundry butter is simply a super-concentrated laundry detergent in paste form. 
 
Advantages:
 
Super concentrated. You only need 1 tablespoon per load. Maybe a little more for heavily soiled clothes or extra large loads. Do not put it in the washer’s detergent dispenser. Put on top of clothes instead. 64 loads per quart. No lifting large heavy containers!
 
Laundry butter softens clothes better than store bought detergents. I eliminated using store bought fabric softeners which saves money! I either put white vinegar in the fabric softener compartment of my washer or use dryer balls.  I don’t add scent for two reasons. The major cause of irritation or allergies to store bought detergents is scent. Also, any natural scent I could add would wash away with the water. If you would like your clothes to be scented, add a drop or two of your favorite essential oil on to a dryer ball.
 
The formula is safe for both top loading and HE washers, cloth diapers, and septic tanks. It works well with city water, softened well water, and unsoftened well water. Nature friendly. No harsh chemicals, no toxins.
 
Overall, I think the stain fighting ability is like commercial laundry detergents, except for protein stains. That is because commercial laundry detergents contain enzymes which break down protein. You may need to pre-treat protein stains. However, my laundry butter seems to do better with oily stains and sweat stains than commercial detergents.
 
Since laundry butter does not contain any bluing, fluorescing agents or whitening agents you may notice some whites aren't as bright after repeated washings. You may want to add Oxyclean or bleach to your whites. Laundry butter can irritate skin. If you get some on your skin, please wash it off. Do not ingest. Keep out of reach of children.
