I buy concentrates on just about all of my cleaning products. This saves money since I can add the water myself and storage space because the packages are smaller and I don't have a hug home. I am trying to go green at my home, and I have discovered that the green concentrates are probably 1/5 the price of the regular. So, for all purpose cleaner spray, I use the concentrate and dilute. For window cleaner, not only do I dilute, I actually over dilute simply because I feel like since you could actually clean windows with just plain water and a good microfiber cloth anyway, why do I need a ton of chemicals (ecofriendly or not) to make my glass streak free? Good news, over diluted window spray still makes your glass sparkle and leaves a few extra cent in your pocket, which is good news for me.
I also dilute dishwashing liquid, hand soap, moisturizer, juice for the kids (they don't need all the sugar anyway), fabric softener (and it still does the job), foundation makeup and mascara (keeps it from clumping or looking 'whore-y'.
