Return them.

Is there anything you can't do?

You're the one limiting yourself.

your own fault for using those tabs in the dish washer. if you knew how they worked with a dishwasher, you wouldnt put anything you dont want micro scratches on

your own stupidity for not learning. i bet you are from the united states

Lots of people recommend acid. Just soak the knife with lemon juice or vinegar and it loosens it up enough to scrub right off.

Barkeeper's friend and a wine cork
Does no one here have knives?

stop chopping up ants maybe?

Throw them out and buy a proper knife.
Treat that proper knife with respect and only hand wash it, you lazy faggot.

I've always used very fine steel wool to spot treat any rust. One anon mentioned barkeepers best friend, which I think would also work.

>>7181167
>assuming he assumed
Maybe he knows OP personally, anon.

>knives in dishwasher
it's like you enjoy having blunt knives

>>7181559
he said "i bet you are from the US"

you don't say that unless you're assuming

Did you use bleach or something?

Even stainless will rust when exposed to bleach.

Dodged a bullet right there

Has little to do with being American, that's simply what untreated stainless steel does with rough treatment.

>>7180904
That's what it's FOR.
Why even have a machine for washing dishes, if you just end up washing things by hand anyway?

Stab everyone

>>7181973

Why not? Dishes and pots take lots of movement to wash and dry. Knives just take two strokes to wash and dry.

If you absolutely want to rape your knives buy some blackened ones or with colored coating.

>>7181982
I've never seen a knife actually visibly discolor in the dishwasher, though. Might be our washer tablets are less hardcore.
They get dull, eventually, but I always assumed that was more or less inevitable when using a knife for its intended purpose of cutting things.

>>7181973
Knives aren't dishes.
Also, putting knives in dishwasher damages them as it dulls them (banging them around a bit, as well as water repeatedly drying on the edge) and increasing corrosion (as seen in the OP).

>>7181175
This. A simple steel wool pad that still has a bit of life in it after scouring a baking tray or something will clear up small spots of rust really quick.

Rust on stainless steel.
There are three ways this can happen:
It's not stainless steel.
Or they were next to chlorine.
Or it's rust from another metal object (flying rust).

>>7182403
>Thinks stainless steel can't get rusty

>>7182403
Stainless steel rusts, it's just more resistant.

If you put a stainless knife in the dishwasher though, those aggressive as fuck tablets and soaps will do a number on it.

>>7182436
This. Putting knives in the dishwasher is bad because of the harsh chemicals and abrasives in dishwasher detergent. That shit will eat away at the finish of a lot of knives and pots and pans.

>>7182436
Basically all my cutlery is made of stainless steel, though. Hell, the interior of the dishwasher is some steel alloy or other. It's clearly possible to make stainless steel that actually does not stain.
It's possible that its too soft or brittle to make knives for actual cutting, though. I don't know how the steel industry works.

>>7182529
>It's clearly possible to make stainless steel that actually does not stain.
Sure, at the expense of its edge holding ability
Stainless steel used for decent knives is quite a bit less stainless than stainless steel used for the insides of dishwashers. I'm not going to comment on whether op's knives are "decent" but a knife made out of dishwasher material is going to be shit at being a knife.

Who the fuck even puts their cooking knives in the dishwasher? It takes like 10 seconds to wash, rinse, and dry. Then again I find dishwashers in general to be ridiculous unless you just had a big dinner party or something.

>>7180864
>Barkeeper's friend

Exact same brand I was going to recommend. I've found it's good for getting of rust / tarnish. It is mildly abrasive like Ajax, Comet, and the like, so, be gentle.

>>7180612
>>7180628
this, it's probably a manafacturing defect

>>7181173
Do the reverse image search thing and see that OP's pic is from an Amazon review and read that review (and look at the other pics).

Consider returning them while the receipt is still fresh, maybe.

>>7180597
>stainless steel knives

Machinist here, I'd say those knives have insufficient nickel content, thus the rust.

Stick a magnet on them, if it sticks they're carbon steel knives, as stainless steel is non-magnetic.

>>7183225
>nickel content
You mean Chromium.
>stainless steel is non-magnetic
lolno

So lazy

You should never put knives in the dishwasher. Ever.

That said, those are apparently shit. Return them if you can. I buy Victorinox knives, they are beautiful and cheap.

>>7183225

Machinists clearly know as much about metallurgy as loggers know about plant biology.

Any stainless used in typical kitchen knives will survive dish washing without corrosion. If a knife rusts it indicated a bad batch of steel or improper heat treatment.

what kind of person would you believe it's most certainly the manufacturers fault?
I've worked over 10 years with stainless steel medical devices and rust problems are just poor raw material batches or crosscontamination with other metals. >>7182403 is me

>>7183225
there are many kinds and grades of stainless steel
some more rust resistant and some magnets will stick to

any real machinist would know this

Always cheese your knives after getting them wet.
