What does Iron Any Temperature mean?
Quick Answer
Iron at any temperature setting
Detailed explanation
The iron at any temperature symbol (an iron icon without dots or with an indicator that no temperature restriction applies) means any heat setting on the iron — from lowest to highest — is safe for this garment. This is one of the most permissive ironing symbols and appears almost exclusively on robust white cotton and white linen, which are the only common fibres that tolerate the highest iron temperatures without damage. The symbol still requires correct ironing technique, particularly keeping the iron moving; the absence of a temperature limit does not mean the fabric is indestructible.
How to follow the Iron Any Temperature symbol:
- 1
Any iron temperature is safe
- 2
Choose setting based on fabric type
- 3
Steam is usually acceptable
- 4
Iron while slightly damp for best results
When does this symbol appear on care labels?
- For white cotton shirts, blouses, and household linens where a high-temperature press is desired
- For white linen garments and table linens requiring a crisp professional finish
- For any robust white cotton item where temperature restriction is not a concern
Tips and Best Practices
- Even with no temperature restriction, use the highest heat (cotton setting) only for thick cotton and linen — start lower for thinner items and work up if needed
- Iron while slightly damp for the best results — the moisture and heat together produce a far crisper press than ironing a dry garment
- Use steam freely at any temperature setting on these fabrics
- Keep the iron moving continuously — a stationary iron at any temperature will eventually scorch even cotton
- Use a pressing cloth over embroidery, buttons, or textured areas even at high heat
What happens if this symbol is ignored
There is no temperature-based damage risk from the ironing symbol itself on these robust fabrics. Damage comes from ironing technique: a stationary iron at any temperature, or ironing over zips, buttons, or embellishments, can mark or damage even the most heat-tolerant fabric.
Common mistakes to avoid
- Assuming "any temperature" means any ironing method is fine — the iron must still keep moving, and embellishments and zips must still be avoided
- Using this as justification to iron other fabrics at the highest setting — this symbol applies to this garment only
