Disclaimer

Last updated: September 2026. Please read this page carefully before using our calculators.

Educational information only

All content on LaundrySymbols — calculators, articles, tables, and examples — is published for general educational purposes. It is not care symbols advice and is not a substitute for a qualified professional. We are not professional cleaners for valuable or delicate garmentss, and no client or advisory relationship is created by your use of this Site.

Care symbols represent the manufacturer's tested safest method — they are not optimal-care instructions, and conservative labeling is common. When a label and common sense disagree on a valuable garment, professional cleaning advice wins.

Symbol standards vary subtly by region (GINETEX in Europe, ASTM in North America) — shapes are near-universal but a few details differ. When in doubt, the mildest instruction wins.

Accuracy of calculations

We implement well-known, publicly documented formulas (see the methodology section on each calculator page and ISO 3758 and ASTM care-labeling standards as applicable). Even correctly implemented formulas produce estimates that depend on your inputs and assumptions. Real-world outcomes vary. Do not rely on a single web tool for a consequential decision.

Advertising disclosure

LaundrySymbols is funded by display advertising served through Google AdSense. Advertisers have no influence over our content, formulas, or editorial choices, and placement of an ad is not an endorsement.
