Dishwashing soap has many uses. If you spill any oil or greasy items on your clothes put some liquid dishwashing soap on the area and rub gently. You can do this as soon as it happens or is you spot before you put it into the wash. If it doesn't come out with the first wash you can do it again. If it can get black funky oil off birds it can get out just about any oil. I got this tip from a friend of mine who was a message therapist who used it to get the message oil out of her clothes.
I use this for my pillow cases and sheets. I put a small amount in the machine before I wash. My husband sweats a lot in his sleep and releases a lot of oil. I swirl this around the washing machine tub once and wash on hot to get all the oils out. I keep a small bottle of this on my laundry shelf.
If you have run out of bleach or need to spot treat a white area, you can use automatic dishwashing machine gel. It is made of bleach and is great in a pinch if you have a small spot you need to bleach.
You can also use dishwashing gel for bad mildew stains in bathrooms. Since this is bleach based, anywhere you can use bleach you can use this product. I have had to use it on a stubborn mildew stain or two. Just coat the area and let it soak for a while. Come back and scrub this will get the mildew out.
You can make your own laundry soap. I am exciting about this one. I am going to be doing this soon. These ingredients are simple and do not cost a lot to make. I am going to be changing the recipe from this one instead of using Fels Naptha, I am going to grate some ivory soap I got for free. Some one else posted you can use this instead.
Make your own softener and dryer sheets. I am exciting about this one too. These ingredients are simple and do not cost a lot to make. I am thinking you can use lotion if you do not have conditioner for this recipe. My husband travels frequently so we have a ton of the little bottles of conditioner, so I am just going to use some of those. Wow FREE fabric softener.
Hope these help. Do you have any tips you would like to share?
