The Shark unscented steam & wipe approach for surfaces cumulatively removes stuff that would get back into the atmosphere. (Use a microfibre cloth and natural antiseptic-antibacterial cleansers. When you rinse the cloth, it's a non-toxic, enviro-friendly reintroduction of gunk from whence it came.)

Be sure to use ONLY filtered water -- no additives -- in the Shark. For airborne stuff (or surface borne stuff) you can also use the following:

All purpose cleaning solution/air freshener(s) -- use what suits your nose and circumstances:

Add to 1 litre/quart of filtered water a capful of Old School Listerine and a small capful (about a teaspoon) of Dettol (or Pine-based substitute).

I've found that Dettol is best, plus, at various strengths, it can be used medically for sterilizing cuts, insect bites, etc. or to disinfect nasty areas like diaper pails, toilets, etc. I add a few drops of Peppermint, Wintergreen or Spearmint natural oils to make a "Febreze" that's 100x better than "Febreze". The scent of it is so familiar now, when I smell it it kind of smells "dirty". :-)

The homemade stuff just smells fresh and new and will clean surfaces or the air.

You can tweak the formula by adding a bit of plain white vinegar by slightly reducing the water. I'd limit it to an ounce or two, though the vinegar smell goes away in a few minutes. This works well with plain baking soda dry scrub.

Find your preferred scent by goofing around with small quantities first, so you don't end up having to tweak a massive gallon of stuff, and make sure whatever oils you use are naturally derived as opposed to supermarket "fake" scents. As mentioned previously, I like mints and woods, citrus peels, and certain spices (like bay leaves, cinnamon bark).

If you're going with citrus peel and vinegar (as per nystray's great vinegar tip), use the Orange Listerine.

I always keep a small bottle spray bottle of half Listerine / half-water in my pack or in my desk when at the salt mine. It safely spot-cleans anything from a mouseball to shoe grime, but you can use it safely on the body too, like cleaning sticky fingers, the pie-hole, under the arms. The Listerine-smell goes away after a moment or two.

For deodorizing shoes, cabinet drawers, etc., fill a loosely woven muslin bag or one of those awful knee-high with dried flower petals, cedar wood chips, tree needles and and shpritz with a non-vinegar containing cleansing solution containing a few drops of aromatic mint-oil. Put this bundle inside your shoes -- esp gym shoes :-) -- and never again experience the Agony of DaFeet.
