The Care File
The Care Companion
Last updated: October 1, 2026
I have watched more good clothing die of bad laundry than of bad design. The fiber tag tells you what you bought; the care label only tells you what the brand hopes will keep it alive until the return window closes. The rest — the real rules — come from how each material is built, and those rules are worth having on one page.
This is that page. Every row below follows the same order of operations: how to wash it, how to dry it, where to put it, and the single mistake that does the most damage. When in doubt, do less — agitation, heat, and time ruin more garments than any detergent.
| Material | Washing | Drying | Storage | The common mistake |
|---|---|---|---|---|
| Cotton | Machine wash cold or warm; shrinkage drops sharply below 86°F/30°C | Tumble low and pull while slightly damp, or line dry to skip the iron | Fold knits, hang wovens; no special care | Drying on high heat — that is where the shrink happens, not the wash |
| Linen | Machine wash cool on gentle; wash separately the first few times | Line dry; press while damp if you want it crisp | Hang on padded hangers; folded shelf creases set hard | Fighting every wrinkle — creasing is the fiber, not a defect |
| Cashmere | Hand wash cool with wool detergent, or dry clean only for structured pieces | Roll in a towel, dry flat away from heat; never hang | Folded with cedar, in a bag; moths find it first | Hanging it — shoulder bumps on cashmere never press back out |
| Merino wool | Machine washable on a true wool cycle, cold | Dry flat; heat is what turns a fit into a felted rag | Folded, with moth protection in season | Treating 'machine washable' as license for the regular cycle |
| Silk | Hand wash cool with silk detergent or dry clean; test dye bleed first | Roll in a towel, iron on low from the reverse while damp | On a hanger, away from direct light; light fades silk | Wet silk under high heat — water spots and shine loss are permanent |
| Velvet | Dry clean almost always; crushed velvet care labels lie the least | Air dry on a wide hanger; steam never touches the pile directly | Hung with space around it so the pile doesn't crush | Pressing the pile flat with an iron — the mark never fully lifts |
| Denim | Inside out, cold, rarely; spot clean instead when you can | Line dry inside out; the dryer is what kills stretch recovery | Folded; hanging by the hem stretches the waist | Frequent full washes — the fade you paid for lives in the wash water |
| Smooth leather | Never machine wash; wipe with a barely damp cloth, condition seasonally | Air dry away from radiators; dried-out leather cracks, it doesn't shrink back | Stuffed and on a shaped hanger, in a breathable bag — never plastic | Trying to fix a stain with household solvents; set-in stains need a pro |
| Suede | Brush dry with a suede brush; water and suede are enemies | Blot wet spots, let dry naturally, brush the pile back up | Cool and dry, with a cedar insert nearby | Wet-cleaning it at home — most 'ruined' suede was simply scrubbed damp |
| Gold-filled jewelry | Mild soap and warm water with a soft brush; dry fully after | Pat dry with a lint-free cloth before storing | Sealed in a small bag, away from perfume and humidity | Treating it like plated jewelry — the bonded layer is thicker and wants normal wear |
| Pearls | Wipe with a soft damp cloth after wearing; never soak the strand | Air dry flat on a cloth before storing | Flat, silk-lined, separate from metal; drilled holes hold moisture | Spraying perfume or hairspray on them — nacre is a surface, not a stone |
A note on scope: this table is the quick reference. The long version — how each material actually fails, and what can be rescued — lives in The Care File, one piece at a time.
