Actually we've been using this recipe for all our clothes for over 2 years. So its good for all laundry, and it saves lots of money compared with Tide, even though it is equally concentrated, or more so...... But compared with cheap laundry detergent, its about 3-4 times more concentrated! When I finally started working for myself, and no longer could depend on a uniform company to supply and wash my clothes, I discovered that my clothes werent getting very clean when I washed them. First problem was the detergent I was buying, it was whatever was on sale at the time! I never bought Tide cause it was always the most expensive. But I've since learned that it's the most expensive because its by far more concentrated than the cheap stuff! But before that, I did an experiment to figure out why my clothes werent getting clean. I filled the washer with clothes and water, and earlier on I added the detergent. The cheap detergent I was using called for 1 full capful(4 oz.) to a large load. But I always added 1.5 capfuls(6 oz.) just to be safe. So I let the washer agitate after putting in 1.5 caps of liquid detergent, then after a couple minutes, I stuck my arm in there to 'feel' the water to see if it had softened and felt slippery like it should. Well, it didnt, so I added another capful, then let it agitate again for a couple minutes, then stuck my hand in again, but it STILL didnt feel soapy and soft yet! Long story short, I had to add in 4.5 capfulls(18oz.) of detergent to get the water softened! From then on, I stopped buying the cheap crap! I went back to the grocery store, and this time I skipped the cheap stuff, I skipped the middle priced stuff, and I bought Tide next time. So next time I did laundry, I tried the same test again, and added just 1 capfull of Tide(4oz.) to a large load, let it agitate, then stuck my arm in and tested the water. Long story short again, with Tide it took between 1 - 1.5 capfulls(4-6oz.) to properly soften the laundry water. THATS why it costs more! But now, I discovered some do-it-yourself laundry detergent recipes online, and I finally tried them. Then after experimenting with ingredients, I came up with a great, very concentrated liquid laundry detergent that is completely home made, and costs about $6 for 2.5 gallons of detergent that it easily as concentrated as Tide, or more so! That much Tide(2.5 gallons) would cost about $55.... The ingredients are: 1.3 4oz bars of Dove soap, or an equal amount of Fels Naptha bar soap, grated 3.5 cups -Borax(Twenty Mule Team brand) Borax is a laundry booster 3.5 cups-Arm and Hammer "Washing soda"(not baking soda, theres a difference, but they both come in yellow boxes) Washing soda is a laundry booster. 2.5 gallons of clean water **Note: You should be able to find the Borax and/or the Washing soda right there in the laundry aisle next to other laundry boosters. The bar soap is grated then added to a pot with 1/2 gallon boiling water to melt it. Then you get a 4-5 gallon bucket, and pour the melted soap mixture into the bucket. Then slowly stir in the washing soda, then slowly stir in the Borax, then add 1 gallon of cool water. Then stir, stir, stir! Stir for 2 minutes or so as the soap starts to thicken. Then add the last gallon of cold water, and stir for another 2 minutes or so. Then put a lid on the bucket and let it sit, but go back every 30 minutes or so and stir for a minute or so. Do this 2 times or so. The stirring keeps the bar soap from clumping up, and makes it smooth. ITS IMPORTANT... Then just let it sit overnight to cool fully. Then stir again until smooth(about 1-2 minutes). Then pour 2 gallons of it into empty milk jugs, and pour the rest into an empty laundry detergent bottle to dispense it from. *Each time you pick up the bottle to pour it in the washing machine, shake it first to mix it a little. Use about 4-6oz per large load in a top loading machine, and 1/3-1/2 that amount in an efficient front loader. This is a non-sudsing formula, so its hard to add too much, and it wont overflow with suds if you do add too much.... The great thing about that recipe is that it is almost 100% all natural, as both Borax and Washing soda are mined from above or under ground as naturally occurring minerals. The bar soap is just Sodium Hydroxide(lye) and vegetable fat, which has been used for hundreds of years..... There's nothing harsh or environmentally unfriendly about this detergent.. It also seem to work as well as any detergent out there!
