Please don't put it in the dishwasher.
Will you please share more information about the reason you wrote to not put it in the dishwasher? Do you own one and had a bad experience doing that, despite the description stating it's dishwasher-safe, for example?
Tho I don't have this - you put any sharp object in a dishwasher it will come out less sharp regardless of quality. Goes for any "cutting" object
Do you have any info to quantify how much a dishwasher dulls sharp objects? It just seems like it might be negligible, potentially.
I'm probably going to continue to wash anything that fits and isn't wood in my dishwasher.
I do not have specific scientific evidence - unknown if studied or not but simple physics would support my offering as high water pressure will dull the cutting edges by knocking them against the rack and against other objects.
Not the water pressure but the mild corrosives in the dish detergent.
That may or may not also be - results the same; sharp comes out of a dishwasher less sharp
No. It is. Other contributer is just rust from being wet.
thanks @@Ryan_Alan & @JOYCEfromNS
@Ryan_Alan I can definitely see the dish detergent (or rust/oxidation) being a factor that can be quantified as having an appreciable effect. It probably also depends on the materials used in making the item, however, I'd hope something touted by the manufacturer as being dishwasher-safe would be made of something where it would take a lot of washings for it to dull the blade in an impactful way.
My dishwasher definitely doesn't allow for items to do much moving around -- none for the special utensils rack on top in my machine.
tl;dr Dishwasher safe is not the same as dishwasher recommended.
The environment inside a dishwasher will dull the blade faster as a combination of things can happen inside, whether if your dishwashing temperature is very hot with strong detergent, or if the peeler blade may clash onto its cage or other utensils. The HRC suggests that the blade will hold its edge at the cost of being brittle, the thin blade of a peeler definitely not going to hold its edge as long as a knife of the same material, so it is in best interest to treat it as a delicate piece and handwash it. Also, peelers are usually used as come and go, as most don't even know how to sharpen a peeler's blade, and to get the most out of a ten dollar peeler while you can buy one of questionable quality at a dollar or cheaper is to prolong its use as much as possible.
Thanks -- this is great information.
I actually have ruined some of my best (favorite) knives, by washing them in the dishwasher. This was before I had read (online) that washing sharp objects in the dishwasher can dull them. I have graduated from the School of Hard Knocks, while others have gone to MIT, but I can tell everyone, from experience, that I will never put one of my favorite knives, or any sharp object that I want to stay sharp, in the dish washer. Seriously.
