'Nice' darks - anything but jeans, socks, dogwalking or gardening clothes - are turned inside out, washed separately from other colors with a 'black' liquid detergent, at 20 degrees or on 'tap cold', cycle depending on the fabric.
Delicates turned inside out, washed on 20 degrees delicate cycle with a 'fine' liquid detergent. The delicate/handwash cycle still spins more than I would like, so very delicate stuff is hand washed the old-fashioned way.
Bright colors, turned inside out, are washed either 20 on 30 degrees, depending on the fabric. Occasionally on 40 if very dirty cotton. Cycle depends on fabric. Liquid color or fine detergent.
Jeans, work clothes, socks washed on 40. Usually use one of the cotton clothing cycles. Powder color detergent.
Bedding on 40 or 60, depending on fabric. Color powder detergent.
Towels on 60, powder white detergent. Heavy cotton cycle.
Dog bedding/towels on 60 or 95, heavy cotton cycle, powder color detergent. 95 is used whenever I need to sterilize for medical reasons.
The only loads that go through a full tumble dry are the towels, husband's heavy work clothes/socks, and dog bedding.
Nice darks, some delicates, colors go in for a 3 or so minute fluff, then are hung to dry. Most delicates do not go in the tumbler at all.
I find that a full dry comes out more wrinkled. A quick fluff, smooth or block and then hang, is IME the best way to avoid wrinkles in my stuff. Much is fabric dependent. Synthetics or fine naturals don't do well in the tumbler, even on low heat*, the fabric ends up faded or otherwise damaged quickly. And shrinks.
Sheets are fluffed or half-dried and then hung to finish, fabric content dependent. Also weather dependent - on a wet muggy day I likely need to tumble dry fully - and then smooth and fold immediately - rather than hang in the cellar. In an ideal world I'd like to hang sheets outside on a sunny breezy day, but that is not allowed in our Quartier.
*One of my complaints with the various driers I have had here is that none have had a 'cool dry' setting. The low heat settings are actually quite hot. Can any of you recommend a brand with a true cool dry setting?
