laundry soap recipe ? in Pinching Pennies Posted March 4, 2012 Originally Posted By: Crazy4Canning 1. How does it keep the colors bright, prevent fading, and fresh smelling? I've never noticed any smell other than clean. My clothes don't seem to have faded at all & seem just as bright as they were before. 2. Couldn't you use bluing instead of soda for brightening? Sorry, I don't even know what blueing is. 3. This caustic combination also tends to dry skin - for those with sensitive skin, wouldn't it wreak havoc on clothes, not to mention the residues on skin? My daughter and I both have very sensitive skin and I think it is much less irritating than the store stuff with coloring (which she is allergic too) and perfumes. I never ever noticed it leaving any residue on my skin or clothes in the year I've been using it. JMO. As to the dry sensitive skin, I use my handmade lye soap and have not had dry skin. It is more moisturizing than store bought bath soaps. It is much easier on the clothes, in my opinion, that store bought. Also the handmade soaps don't have any fillers in them. Take two glasses half full of water, add a teaspoon of store bought laundry soap to one and stir to dissolve, Then, add a little less or the same amount of handmade laundry soap to the other glass and stir. See which has things floating in the bottom. The only other laundry soap that I have found that didn't have additives was from Amway. And you only used less than a quarter of a cup to a large load of clothes. It makes me wonder if it was all natural.
