It depends on the machine and how the owner programmed it, but published factory settings run from about 110°F on the lowest setting to 190°F at the top of the range. A Dexter stack dryer ships with Hot set to 175°F, adjustable from 150°F to 190°F. A Speed Queen Quantum single-load dryer ships with High set to 160°F. Owners can change these settings, so two laundromats with the same machines may run at different temperatures.

Many people wonder whether laundromat dryers run hotter than the dryer at home. It is a fair question if you are drying wool, activewear, or anything with a “low heat” label. Below are the actual factory settings from two common commercial dryer lines, what the buttons on a coin dryer usually mean, and how to pick a setting for different loads. For more on shop visits, see our coin laundry guides.

What temperatures do commercial dryers use?

Commercial dryer controls let the owner program each heat setting within a range. These are the factory defaults and ranges published by two manufacturers:

Dryer	Setting	Factory default	Adjustable range
Dexter stack dryer (T-30)	Hot	175°F	150–190°F
Dexter stack dryer (T-30)	Medium	150°F	120–170°F
Dexter stack dryer (T-30)	Warm	125°F	110–150°F
Speed Queen Quantum single-load	High	160°F	110–160°F
Speed Queen Quantum single-load	Medium	155°F	110–160°F
Speed Queen Quantum single-load	Low	145°F	110–160°F
Speed Queen Quantum single-load	Delicate	115°F	110–160°F

Both documents also list a cool-down period at the end of the cycle: 2 minutes by default on the Dexter stack dryer and 3 minutes on the Speed Queen single-load model, each adjustable by the owner. The Dexter control even lets the operator display the current temperature of each tumbler. A customer usually only sees the buttons, not the numbers behind them.

What do the buttons on a coin dryer mean?

Labels vary by brand. On the Dexter model, the three choices are Hot, Medium, and Warm. Speed Queen’s single-load dryer offers High, Medium, Low, and Delicate. Some machines use words like Regular, Permanent Press, and Delicates for the same idea. As a rule of thumb, the highest button is meant for sturdy cottons such as towels and jeans, the middle setting for everyday mixed loads and permanent press, and the lowest for delicates and synthetics. If the buttons are not clear, ask the attendant.

Which setting should you use?

Towels, sheets, cotton jeans: the high or hot setting is usually fine if the care label allows it. Check heavy items before you leave; thick towels can still be damp after one cycle.
Everyday clothes and blends: medium or permanent press is a safer middle ground.
Fleece, polyester, and activewear: low or delicate. See can you put fleece in the dryer and how to wash polyester.
Down, puffer jackets, and pillows: low heat, with a longer run time. See can you put a puffer jacket in the dryer.
Anything labeled “do not tumble dry”: take it home and air-dry it.

If you are worried about shrinkage, start on a lower setting and add time. Our guide to whether dryers shrink clothes explains why heat plus tumbling is the usual cause.

Is a laundromat dryer hot enough for lice or bed bugs?

For head lice, the CDC says to wash items in hot water (130°F) and dry them on high heat. The factory high settings above are all above 130°F, but because owners can reprogram them, you can’t know the exact temperature of a particular machine. Use the hottest setting the care label allows and run a full cycle. For lice laundry steps, see does laundry detergent kill lice. For bed bugs, see can you get bed bugs from the laundromat.

Is it safe to leave clothes in a hot laundromat dryer?

Take loads out promptly. The cool-down at the end of the cycle exists to bring the load’s temperature down before you unload it. Leaving a warm, tightly packed load sitting in a stopped dryer is not a good idea, and many shops have rules about unattended laundry anyway. Read can I leave my clothes at the laundromat, and clean the lint screen if the machine lets you. If you use dryer sheets, read are dryer sheets safe first.

Frequently asked questions

Are laundromat dryers hotter than home dryers?

They can be, but it varies by machine and by how the owner set it. A Dexter stack dryer’s Hot setting can be programmed as high as 190°F, while a Speed Queen Quantum single-load dryer tops out at 160°F.

What is the lowest heat on a laundromat dryer?

The published ranges start at 110°F. Speed Queen’s single-load dryer ships with Delicate at 115°F, and Dexter’s stack dryer ships with Warm at 125°F.

How long does a laundromat dryer cycle last?

It depends on the vend price and how much time each coin buys. The Speed Queen single-load model ships with a 45-minute cycle, but owners can change it. See how long coin laundry takes.

Will a laundromat dryer shrink my clothes?

High heat can shrink cotton and damage synthetics. Use the setting that matches the care label and check the load partway through.
