I'm a less-is-more when it comes to laundering and dry cleaning, because I find the more you do, the faster the garment wears out. Also I have had so many items ruined at the dry cleaner, or never look the same way again once it went through the wash (even hand wash). So I have developed a lot of strategies to minimize need to wash:
- I don't wear perfume and I no longer smoke (in my experience, two of the biggest offenders for need-to-wash).
- I don't even wear deodorant all that often (mostly in summer), as I find that deodorant degrades fragile fibers faster than sweat, or I will wind up with white smears on my clothes (hate when that happens!)
- I change out of my good clothes and into sweats/loungewear when I get home.
- I wear an apron on occasions when I cook with good clothes on
- My kids are all grown up and don't slobber all over me (I needed to do laundry far more often when they were younger!)
- I always wear a scarf with my winter coats, to prevent makeup from getting on the collar.
- I wear skinnies tucked into boots or -- I just don't prescribe to perfect PPL because I'd rather not have my pants dragging on the floor.
- I vastly prefer sleeveless and collarless, because these stay clean longer.
- Weather permitting, I wear a slip under dresses, and camis under blouses.
- I do not style my hair and do my make up while wearing clothes.
With all of that, I find most of my "good" clothes stay clean through several wears. I realized awhile back that I was washing things because they were rumpled or linty, rather than actually dirty or smelly. So, clothes get a lot more use if you hang them up when you get home, use the lint brush on them, allow time for the garment to air out between wears, and run an iron over them or steam clean out the wrinkles.
In the next category are clothes that aren't dirty but have picked up odors (body odors, smoke odors, cooking odors); a run through dry-el helps those. Or items that aren't dirty but have stretched out (I hate that category but I do have a few items like that). Then you have garments that are genuinely dirty, like underwear, slips, camis, loungewear, pj's, tee shirts worn to clean or cook, exercise gear, beach cover ups. Those go through the wash after one wear.
While I dry-el my sweaters a few times each season, I wash them only once a season. I have a LOT of sweaters, so they all get rotated and have ample time to air out, in the wire drawers I keep them in which keeps air circulating. For those who find wool itchy: I have found that if you can tolerate the itch for a wear or two, it goes away, because your body oils get on the wool and create a barrier... until you wash the sweater in water. So, washing sweaters infrequently really helps here.
If in doubt, I ask DH to give me a sniff test.
