For some reason I am revolted by perfumed consumer products and it irritates the hell out of me that I can't find any cleaning or personal hygiene products that aren't overloaded with synthetic fragrances. Now I try to make my own semi-homemade cleaning products using scent-free ingredients.
Isopropyl alcohol and ammonia solution are the best cleaners in the world, used separately or in combination. A mixture of roughly equal parts isopropanol, ammonia, and water produces the perfect surface cleaner which leaves no residue and cleans glass better than Windex only with no blue dye or cheap industrial perfume and a whole lot cheaper. Alter the three ingredients to taste, even a very dilute solution is useful to wipe dust off teevee equipment. The combination with less ammonia and more alcohol or just alcohol can be used to clean your skin when bathing isn't possible. Fill a spray bottle with the alcohol and water with just as much (clear!) ammonia you can stand, spray on a clean paper or cloth towel, then wipe your face, underarms, or whatever is oily and smelly. It also makes a good surface sanitizing spray because no bacteria or virus could withstand the combination and because it also evaporates away completely leaving no residue.
Then there's glycerin. I've become addicted to unscented glycerin soap, and liquid glycerin is also good to add to regular liquid dish soap because it created more substantial lather. Glycerin seems to act as a lubricant between surface and dirt and lets the dirt be washed away. Glycerin soap dissolved in hot water makes a wonderful bubblebath solution, and adding extra glycerine creates the most luxurious hypoallergenic skin soaks imaginable.
I'm going to plug Kirk's coconut oil soap because it is awesome and cleans so thoroughly that after I come out of the shower even my farts are odorless. Add some glycerine soap to the lather and it moisturizes your skin and hair and everything rinses away so clean.
For laundry it is whatever fragrance-free brand like All or Purex or Tide Free, along with lots and lots and lots of borax and baking soda, and varying amounts of oxygen powder bleach. Chlorine has been banished since it gives me a sore throat.
For mopping floors an incredible floor-cleaning solution can be made by mixing unscented laundry detergent with Pine-Sol and ammonia. I know the Pine-Sol is scented, but I like it and if you don't then the laundry detergent is still great and cheap and it requires no rinsing because it isn't slippery like dish soap.
Baking soda is also useful for brushing teeth, though I always add some Tom's toothpaste to make it more palatable. Oh, and don't forget the hydrogen peroxide rinse before brushing, letting it fizz between your teeth for a few minutes before sandblasting them with the baking soda. Baking soda also is good for cleaning silver jewelry, rubbing it over the metal with your fingers to remove soil and polish at the same time.
So far I haven't found a satisfactory unscented dish soap. I've always used Ajax because it mixes with ammonia and alcohol and because the lemon scent isn't offensive to me, but I do wish it came in a fragrance-free version.
