https://jdstillwater.blogspot.com/2012/05/i-put-toaster-in-dishwasher.html Run Deep Tuesday, May 15, 2012 I Put a Toaster in the Dishwasher I put a toaster in the dishwasher. I know; some of you have just decided that I am a total moron, and won't read further. That's OK. I learned two very important lessons from this little experiment: (1) It is very difficult to discern the difference between Conventional Wisdom and Conventional Ignorance; (2) When Conventional Ignorance is challenged, things can get nasty. So, I had this toaster that had several years of dust, grease splatter, and burned greasy crumbs stuck way down inside. I had heard that people sometimes put computer keyboards in the dishwasher, and that this is OK as long as you let them dry thoroughly before connecting them again. So I looked online about cleaning toasters in the dishwasher. A few places, a few people have tentatively asked "Can I put a toaster in a dishwasher?" The conventional wisdom was nearly unanimous: "What kind of F--ing idiot would put a toaster in a dishwasher?" The tone alone made me want to find out more, because I thought those creative questioners at least deserved a real answer to a fair question. Dear Reader, before continuing I must tell you that I am a Physics teacher. I know a few things about electricity. Some of what I know was hard-earned. For example, in my first year of teaching, during my first period Physics class, on the first day of Electricity, I plunged a hair dryer running on "High" into an aquarium full of tap water to demonstrate how Ground-Fault Circuit Interrupters work. It kept running. All day. We could see the water going through the hair dryer, getting sucked in the back, passing through the heating coils and getting blown out the front, round and round, slightly warmer with each pass. All that day, kids got to see Mr. Stillwater's hair dryer running under water in a fish tank. I thought I knew about electricity and water, but what I possessed was Conventional Ignorance posing as Conventional Wisdom. Humbling. Skip ahead fourteen years and I know a whole lot more about water and electricity. What I don't know is whether there are parts in a toaster that might be destroyed by water, destroyed in such a manner that a good drying out won't cure. But I persisted, and here are some more samples of Conventional Wisdom, from YahooAnswers, with literacy-level intact. The question was "Can I put my toaster in the dishwasher?" you mean , mommy's toaster...theres no way you could have made it to adulthood... Sure you can, you can also do the same for your cordless phone, small TV, laptop computer, just anything that will fit into the dishwasher. Really now, Use your head for something other than a hat rack. As previous answers have stated, NO, IT WILL RUIN THE TOASTER!!!!! Only do it if you want to buy a new toaster. The water and harsh chemicals of the dishwasher will cause the electrical element to corrode. NO! A toaster is an electronic device. The dishwasher will soak it and ruin it. You can put your toaster in a dishwasher you can also put your hairdryer and CD player in a dishwasher BUT from a safety perspective it's very dangerous. Water will seep into the heating elements of the toaster and may not dry off. Plug in the toaster and you'll short circuit the toaster and probably start a fire. I chose these seven examples because each writer is either clearly wrong on their main point based on my own first-hand knowledge, or is strident without evidence. For example, I might respond: "Sorry #5, but a toaster is an electrical device, not an electronic one, and I've already soaked an electrical device in a fish tank for several hours, while it was running." These commenters are speaking authoritatively on subjects about which they are completely ignorant, but they are strident in doing so because they are repeating what everybody knows. They are intellectually secure in the center of a vast mob; their wisdom was received, not crafted. It doesn't need to be crafted, because it is already known, established, beyond question (but demonstrably wrong). This is Faith, presenting itself as Reason, with sarcasm. For my part, I 'kept the faith,' and continued searching for Reason. I found two blogs (and one comment) on which people admitted putting a toaster through a dishwasher. In every case they let it dry for several days, then plugged in and used their fully-functional, beautifully clean toaster. They were a bit sheepish in reporting it though, as if maybe they just got lucky. I vacillated. A colleague pointed out that toasters are cheap. So I tried it. Mine works, too. JD Ps: Yeah, I know. I have to say more about the fish tank thing before your head explodes. I learned two things that day long ago: (1) Tap water is a poor conductor at 120 volts. I already knew from chemistry that distilled (pure) water is not conductive at all, but tap water is pretty far from pure. As it turned out, I had to stir an entire cylinder of table salt into the aquarium before it shorted inside the hair dryer and tripped a breaker. Even then, when I rinsed the hair dryer and let it dry itself out for a while, it worked fine. I still have it, and it still works. A year later the school's band-room got flooded by a burst pipe. I helped rescue the digital pianos, which were all plugged into a power strip under four inches of water. We could see it from the steps, but no one wanted to go into that water! With the fish tank/hair dryer episode in mind, I took off my shoes and waded in. No problem, until I planted my bare foot on that bare concrete floor a few inches from the submerged power strip, at which point I felt a mild but discernable tingle in that one foot. I unplugged the power strip from the wall above the water line, and the tingling stopped. Onlookers cheered. (2) GFIs only trip off when in bodies of water that are grounded. They won't work in an aquarium sitting on a lab table, or in a plastic laundry sink with plastic drainpipes, or in a plastic shower with plastic drainpipes. That doesn't mean you're not protected in those situations; the GFI will trip when it detects that current is leaking out some other route than expected. That is the condition for you to get fried - electricity has to go through you (or the water) to the ground. The GFI prevents that. If there's no way for electricity to get to ground, it won't go through you, and it won't trip the GFI.

[] Linda WyattMay 16, 2012 at 7:53 AM I once had a cashier INSIST on putting the extension cord I bought into a plastic bag because it was raining out, and she was worried I'd be electrocuted if it got wet. Yeah. You do realize, of course, that what you've written applies to far more than electricity and water. People, in general, are HAPPY with "conventional ignorance" about most everything, and cling to it strongly. ReplyDelete Replies Reply 2. [] Aaron WinbornMay 21, 2012 at 10:36 AM In defense of conventional ignorance, it is easy and safe to avoid something that may or may not be harmful, as opposed to, say, just picking up and eating a wild mushroom, assuming one does not have the training to discern edible mushrooms. I imagine that it pays off with dividends throughout evolutionary history. ReplyDelete Replies 1. [] JD StillwaterMay 21, 2012 at 2:19 PM Good point, Aaron.

I do want to point out, though, that if you have an expensive 'smart' toaster with a digital display and stuff then you shouldn't purposely get it wet. Perhaps this a good argument for not buying an expensive toaster. You can't clean it! ;-) ReplyDelete Replies 1.

[] AnonymousDecember 22, 2014 at 3:49 AM Sooo I left my toaster outside on the patio table 6days ago and since then it has rained 3days in a row on and off. I'm wondering if I hang it upside down for a few days and let it dry out if it will still work. At first I was like "bumb that toaster " and now I'm just like "crap I won't have my toaster " let me add that I'm too cheap to go buy another one. ReplyDelete Replies 1. [] JD StillwaterDecember 22, 2014 at 5:39 AM Anonymous, if you let it dry thoroughly, and plug it in under safe conditions (no flammables nearby, preferably outside on a large concrete slab, etc) it should be fun to find out! After several days in the rain, it is likely to have some rust and other degradation, so I would do this very carefully, but I would do it. To speed drying and stop the rusting, you could preheat your oven to something low, say 200 degrees, then turn it off and put the toaster in the oven. Make sure you turn the oven off before putting the toaster in, and no higher than about 200, because the toaster has some plastic and rubber parts. Delete Replies Reply 2. [] Russ YoungNovember 23, 2021 at 9:14 AM In my experience, moving air is more effective than heat for drying things. Put the toaster in front of a fan for a few days. (Yes, I realize this is extreme necro, but, I do what I want.) Delete Replies Reply 3. [] JD StillwaterNovember 24, 2021 at 5:00 AM Thanks, Russ. You're right, of course, but the ideal is both heat AND air movement. Heat decreases the relative humidity of the air while increasing the vapor pressure of the moisture in the toaster, while air movement increases evaporation. A strong fan on a rainy day won't do much. Neither will applying heat inside a plastic bag. It takes both. Thanks for the comment! Delete Replies Reply Reply 8.

I'm sure a dishwasher works just as well. Also, I heated my oven to 150deg, then shut the oven off and put the toaster in for about an hour to be sure it was dry. Don't let the cord touch anything hot. ReplyDelete Replies Reply 13.

[] JD StillwaterJanuary 14, 2019 at 2:18 PM Your toaster is probably "toast." But if you let it dry out COMPLETELY and then plug it in somewhere on concrete or metal with nothing nearby, you might get lucky. My guess is that the smell was from not cleaning it well enough, AND not letting it dry all the way. Depending on the weather where you live, you might have to let it dry for a week before plugging it in. If you have any doubts, toss it and buy a new one. They're not that expensive. Fires ARE expensive. Delete Replies Reply Reply 18. [] UnknownMay 29, 2020 at 4:38 AM I found your article by searching for "dishwasher safe toaster", because I wanted to buy a toaster I can actually clean thoroughly on a regular basis. I made a dust cover for my toaster, but it's just not enough. I've never found a toaster that was designed to be cleaned in the dishwasher, but I would sure like to have one. I mean, don't all these people think their toaster should be cleaned often, just like all their dishes, pots, and pans? It seems unreasonable to cook food in a dirty appliance.

I found one for less than $10 thanks to Mainstays. ReplyDelete Replies Reply 20. [] josephOctober 18, 2021 at 10:04 PM This comment has been removed by a blog administrator.

[] AnonymousAugust 13, 2024 at 4:52 PM I'd probably spray it out with a hose or put it in the bath first, out of fear that otherwise charred crumbs will make their way into the water channels in the dishwasher's sprayer arms and stop water from spraying out of the little hole in the arm that makes the arm rotate thereby preventing my dishes from getting clean.. or worse that they'll get somewhere where you can't see em and then slowly rot and make your dishwasher sump water smell horrible. But idk the dishwasher people are just like 'how did you get my home phone number oh my god are you in my backyard right now' typical scammers ReplyDelete Replies 1. [] JD StillwaterAugust 14, 2024 at 6:25 AM I've had some dishwashers that clogged in this way and others that didn't. With my current one, I would do as you suggest - a gentle clean-out of larger crumbs first. Thanks for the comment! Delete Replies Reply Reply 22. [] AnonymousAugust 14, 2024 at 1:37 AM Hey, great post and very informative; UK person here with MEng in Electrical and Electronics. Regarding the toaster, my Mother had a challenge with her new toaster keep tripping out the RCD a few weeks back - it turned out there was a single raisin in the bottom of the cage that brushed the element as the toaster popped! Regarding the hair dryer; no hair dryer I have seen has an earth point, and thus you are looking for a significant current between live and neutral to kill the power. In the UK that would be 30A on a ring main, which as you say requires good conductivity between the power connections on the heating element. Don't stop thinking for yourself!! Cheers!! ReplyDelete Replies 1. [] JD StillwaterAugust 14, 2024 at 6:28 AM "Ring main" isn't a familiar term, but if you mean normal household outlets, 30A is a LOT! Here in the U.S., 15A and 20A at 120V are both common for households. Of course, even 15A is plenty deadly under the right circumstances. Thanks for the comment!
