If they are synthetic, I doubt there will be an issue other than potentially more wrinkles. A majority of my Lululemon is washed in hot without an issue.

I would be very very surprised if you damaged the clothing. I've washed polyester wicking shirts on "Sanitize" once, trying to get the funky smell out. No harm done. Any elastic waist bands should survive a single wash at those temps, so you'll be fine.

I wash almost everything on "Sanitize" cycle, including workout gear. No problems.

I wouldn’t dare wash any work out clothes in anything but hot. Body oils do not come out in cold water.

I am sure that they are fine. You can't kill that synthetic fiber. It will still be here long after human populations have either evolved or no longer inhabit the earth.

It will not even decompose if it is burned. Still, a pile of plastic to last for eternity, and beyond.

A hot water wash is not going to destroy it.

Too much heat can deform synthetic/plastic fabric fibers. However, a wash with hot tap-water is unlikely to reach that point. Much of the heat is lost to the mass of the clothes and machine, especially a frontloader or HE toploader which takes in a smaller volume of water. A sanitize cycle possibly could cause damage depending on whether an onboard water heater is involved and what is the target temperature (most still don't get hot enough). The OP references a 60°C cycle, which means it's probably a Miele or some such that has water heating. 60°C is 140°F, which is not to sanitize levels.

A half hour at that temperature is unlikely to do any harm.

However, I think we should kill the myth that things need to be hot washed to get them clean. Blood and sweat (not sure about tears) wash better at colder temperatures. Most of the cleaning is from the enzymes in the detergent rather than the temperature.
In the case of sickness a hot cycle is often a good idea to sanitize things, but not necessary the rest of the time. Team Sky/Ineos travel with nine washing machines-one for each rider, to avoid the risk of cross contamination. I'm guessing nonenofnus is on that league.
I have nothing against a hot wash. People can do as they like. But let's not pretend the rest of us are not wearing clean clothes.

"You can't kill that synthetic fiber. It will still be here long after human populations have either evolved or no longer inhabit the earth."

I've stopped buying it, with this being one of the reasons.

A hot iron will melt it, but that's a lot higher temp than 160°F water. JMHO

One of my washers has a special cycle for Sweaty items, 122°F wash. Special cycle for Blood/Grass (protein) stains runs a cold pretreat followed by a 115°F wash.

dadoes, does it actually say "Sweaty" on the display?

Oh, my! It really does! I find that completely laughable!

It is a bit like the radio/player in my old truck that, when you turn it off, says, "See you!". What!!!!!!?????

All of those preset designations and it could be confusing to select an option because you don't really know what it is that is affected when you select that option. What do you suppose is the difference when one is selected over another? Does it have, maybe an extra rinse cycle that prerinses the sand out?

We don't have much choice when we go to buy a new appliance. Today it is difficult to even buy a new appliance at all.

All of these smart appliances have a vulnerable circuit board in there. It is my considered opinion that many of these things can end up causing complications that outweigh whatever benefit they may offer. That is my opinion, you may have a different view of it.

It is not just smart appliances that this happens too . Whenever a product manufacturer tells you that they have improved it and made it better....it rarely is so. What they have done, often, is just to add more selling features and make you think that you are buying a higher quality product than may be the case.

My iPhone keeps updating and adding all of these feature that are supposed to make it better for me and I have no idea how to use them or why I would want to.

I used to sell in the retail world and the first lesson that I learned about selling a product is to not just tell the customer about the features of the product, rather, to tell them what it can do for them. They can relate to that. Just to tell them that his has triple bladed whiz bangs that emit air flow and limit intake can befuddle them. But, tell them that it cooks their waffles to perfection and they understand that.

We don't have much choice. We can't build our own washing machines or ranges or any of the sort.

@DallasAnnie,

The machine is a Fisher & Paykel IWL12 Intuitive Eco. Two months shy of 16 years, no repairs thus far. It has many options and functions (six temperatures, several rinse options, soak, prewash, drip-dry, time saver, etc.). One basic cycle with Fabric Care choices for Perm Press, Woolens, and Handwash. Thirteen preset special cycles. The basic cycle can be customized for the most-used options and all can be modified ad-hoc with the various options. The user manual details what each cycle does and what each option changes.

Muddy runs prewash (drains the water), wash, two agitated rinses, and spray rinses in the spin. Beach Gear is Muddy without the prewash. Sports Shoes sets a high enough fill to avoid excessive battering-about from the agitator, runs moderate agitation speed with 15 mins soak and two rinses.

Your washing machine is much too capable of communicating. Really? A silly face?

I guess you can just smile back at your washing machine.

I mean no disrespect for your choice of appliance. Please don't assume that.

But I am so surprised that a company would use such imagery in their product. It seems so silly.

At my sons house they have one of those new washing machines that plays a little jingle when it is finished.. That little jingle annoys me to no end. I want my appliances to do no more than a simple ding when finished.

LOL, you've seen very little of what the machine can display.

The end-of-cycle graphics are displayed for a only few seconds so it's blank unless the user is standing there waiting for it to finish. The signal is a simple beep, choice of 0, 5, or 15 times.
