Start with the label,
not the laundry basket.
For a gentler wash day
Fibre is only part of the story. A cotton shirt with a delicate trim may need different care from a cotton towel. Check the sewn-in instructions first; they account for the finished item, including its lining, colour and construction. If the label is missing, choose a cautious method and test an inconspicuous area before treating a stain.
Empty pockets, close zips and separate items by colour and care needs. Turn printed or dark garments inside out. Measure detergent for the load and your water hardness: extra detergent is not a substitute for the right wash. Leave room in the drum so fabric can move and rinse.
A note on stains
Blot a fresh spill with a clean cloth instead of rubbing it deeper. Avoid heat until you have checked that the stain is gone. Follow the treatment product's instructions, and test colourfastness first. Persistent marks on a delicate or valuable item are a good reason to seek professional care.
