The square with a circle and two dots
Sep 20, 2026
Short answer: Two dots inside the circle mean tumble drying at normal heat. It is allowed, but it is still the hardest treatment the fabric can get in an ordinary home. Low heat or air drying is usually the milder choice.
Two dots mean normal heat
If you see a square with a circle and two dots, the item may be tumble dried at normal heat. It is allowed, but it is not the mildest setting, and it is still the hardest treatment the fabric can get in an ordinary home. The symbol only says what the fabric can take, not what is best.
Up to eighty degrees
Normal heat means the air in the drum can reach about eighty degrees. That is a clear difference from low heat, which stays below sixty degrees. The gap looks small on paper but is felt in the fabric, especially if you dry often. Always check how many dots sit in the circle before choosing a programme.
Stiff and brittle fibres
Eighty degrees is enough to make fibres stiff and brittle over time. This is clearest on dense knits such as men's bamboo undershirts, where the fabric sits close and the elastic is always working. The damage builds slowly, so you do not notice it from one round to the next. Only after many rounds does the difference show.
Two dots are not a recommendation
The symbol tells you what the fabric can take, not what is wise every time. Use it as an upper limit, not as a default setting. Choose lower heat when the laundry does not need more. That way the fabric stays supple for longer, and you use the label's permission only when it is really needed.
Low heat is almost as fast
A round on low heat is almost as fast and much milder on bamboo sweatpants for men. The drying time is only a little longer, and you spare the fabric a heavy load. It is a simple change that takes no extra effort. Switch the programme once and you will hardly notice it in daily life.
Save the high setting
Save normal heat for towels and bedding, and let clothes dry on low heat or in the air. That also goes for socks for men. Towels and bedding are not clothes with elastic that must hold their shape. Divide the laundry into two loads so you can choose the right setting for each.
Check stains before drying
Heat can set stains, so a stain that is not gone before drying often becomes permanent. Look through the laundry when it comes out of the machine, and air dry any piece that still has a mark. Repeat the wash before it goes into the dryer. It is a small check that can spare you a lasting stain.
How to decide each time
Ask yourself whether the laundry needs heat to dry or whether the air can do the job. With weekly use, two dots typically cost a quarter of the elastic's life, so it is a price that counts. Make low heat or air your fixed rule, and use normal heat for the few items that take it best. Then the clothes last longer.
Frequently asked questions
What do two dots cost in lifespan
With weekly use, typically a quarter of the elastic's life. That is a clear price for a few minutes saved, so choose low heat or air whenever you can.
Is it faster than low heat
About twenty minutes on a full machine, no more. That is why low heat is a good choice, since you spare the fabric a heavy load without losing much time.
Can heat set stains
Yes, a stain that is not gone before drying often becomes permanent. Check the laundry when it comes out of the machine and wash again if a mark is still visible.
