| bumblebeez - Doing laundry is a lot like cooking and baking. There are a lot of "rules" and a lot of "science", then there's what everyone actually DOES! From habit, experience, science, or without a clue - we all seem to do things a little differently when it comes to laundry. If I say you MUST use hot or warm water with homemade laundry soap mixtures, there will be 10 people chime in to say they only use cold water with it; so you'll have to work this out for yourself, according to YOUR results. Hot water has always been suggested for removing dirt from heavily soiled items, until we decided to "save the planet" by only using cold water. Cold water washing works best with detergents designed to be used in cold water - Gain may be and that could account for your satisifaction with the product. If you want a good test to see how well your detergent has been performing in cold water, wash a load of towels with nothing added to the washer but hot or warm water and see if there are a lot of suds. I'd also say it will take 2- to 3-months of continual use of homemade laundry soap to see if your whites are dingy from hard water soap scum. It will take several weeks to rid your laundry of the accumulation from the Gain. I got my best results using the hottest water I could for the fabric types being laundered. Hard water requires more soap or detergent, as a general rule, so you may have to alter the amount of homemade laundry soap you use depending on the hardness of your water. Whites may turn gray if there isn't enough soap (or detergent) used, or if clothes are not thoroughly rinsed. To get clothes white again, this is a procedured to follow from a Cooperative Extension Service laundry guide sheet: *Wash the clothes again in HOT water. *Add enough water softener to make the water feel slippery. *If the water becomes sudsy, the clothes were not rinsed enough. Wash them again adding only water softener. *If the clothes do not whiten, add soap or detergent and rewash. I've also used Cascade Dishwasher Detergent in hot water and a good soaking to remove the dingy gray hard water mineral deposits from white clothes washed in homemade laundry soap. If you've always used cold water, I was wondering why you want to add Oxi-Clean to the mixture? Oxi-Clean works best in warm to hot water, not cold. So once again, that's wasted money in your homemade mixture. Most people who use homemade laundry soap mixtures don't recognize the principal difference between a soap and a detergent - which is primarily the behaviour in hard water. Soaps tend to get together with the metal ions in hard water forming a scum, while detergents do not. As chris8769 pointed out, soaps are not suitable for use in acidic conditions, and there is all kinds of molecular information on the subject when you study soaps VS detergents. When you switch from a detergent (Gain in your case) to a soap-based mixture, you find the mixtures lack enzymes to attack stains, builders to soften water and assist surfactants, optical brighteners to make clothes look whiter, and a long list of other things. Good luck in your trials with homemade laundry soap. It may suit your laundry needs, and budget, perfectly. If not, you can always go back to detergents. Here's a new combination I read recently: 1 T. Simple Green and 1 scoop washing soda (sorry, they didn't say how large a "scoop"). We're all getting creative trying to save a dollar these days. -Grainlady |
