A care label is the first place to look before cleaning a garment. It communicates the treatment intended for that particular item, and its symbols may cover washing, bleaching, drying, ironing and professional cleaning.
Read the whole label
A wash tub symbol relates to washing; dots and numbers can indicate temperature, while lines may indicate a gentler process. A crossed-out symbol means that the corresponding treatment should not be used. Woolmark explains common symbols in its care guide, but formats and conventions can vary by market, so consult a local guide when a symbol is unfamiliar.
Follow the most restrictive instruction
If a garment says not to wash, do not assume that a delicate cycle is safe. If it allows machine washing, check the specified temperature and cycle. Garments with mixed fibres, linings, trims or special finishes can require care different from a simple fabric swatch.
When in doubt, ask
Keep the label attached or photograph it for reference. For an unclear instruction, contact the manufacturer or a reputable professional cleaner before treating the item. A small delay is preferable to guessing about heat, bleach or solvent. This guide is introductory; the specific garment’s label takes precedence.
