Acidic peroxide solution is also known commonly as piranha solution. You can clean silicon wafer by dropping them in. Any organic residue is toast, however.

- foobarian 3y agoSounds enticing for cleaning burned baking dishes! I tried with concentrated NaOH and that didn't work so I need more extreme solutions.
- barrkel 3y agoOven cleaner is a better bet.
- cowthulhu 3y agoThat seems like a terrible idea on many levels. Will definitely make for some fun anecdotes though (assuming nothing goes wrong). Also - I don’t know if I’d want to eat anything cooked on a baking dish exposed to so many toxic chemicals. I assume you’re not joking, but this was a major whoosh if you were!
- foobarian 3y agoWell, I was not. I keep thinking there has got to be a way to dissolve the black, caked on oil resins, and so far I haven't found a solvent that works. I tried the relatively harmless stuff found around a household; the more aggressive being the lye solution, brake cleaner, acetone, citric acid, muriatic acid (i.e. HCl but relatively weak). Sibling has a good point to try more heat, which should be easy to try since the object is stainless steel.
- cowthulhu 3y agoGotcha! I don’t mean to dunk on you… sounds like a cool project if you take appropriate safety precautions, but the possibility of accidentally creating some poisonous (or carcinogenic) substances seems pretty high. I’m far from and expert though. I might have a low risk tolerance, but I would toss any cookware touched by, like, half of the chemicals you listed. Don’t want to find out the hard way that some nasty layer of something is slowly leaching into my food. If you do move forwards with this, definitely write up your findings... "Removing burnt food with piranha solution without dying" will make a great blog post.
- tomn 3y agoIf it's on stainless steel, why do you need to remove it chemically? Does a stainless steel scouring pad not work?

- beenBoutIT 3y agoI would try piranha before trying more heat as the piranha is less likely to warp or discolor the stainless. If you know what you're doing the equation boils down to determining if the container's worth more than the piranha solution will cost you to make in time/money spent. https://drs.illinois.edu/Page/SafetyLibrary/PiranhaSolutions https://drs.illinois.edu/Page/SafetyLibrary/PiranhaSolutions
- mauvehaus 3y agoI don't know how baked on you're talking here, but we somewhat routinely end up with oily residue that's still in the sticky to moderately hard state. Baking soda and peroxide cleans that shit off like magic. You should Google the exact procedure and proportions. Edited to add: a single edge razor scraper is worth a try on stainless. The razor blade is roughly as hard as the substrate, so you won't gouge it too bad. Get the plastic Allway holders. The metal ones are garbage and, incredibly, the generic plastic ones are pretty inferior.
- foobarian 3y ago> I don't know how baked on you're talking here Very :-). I'm talking about a pan accidentally left on the grill or in the oven for too long until it smokes. The residue is pretty much what you end up with when seasoning cast iron cookware, and is very hard and resistant to usual household chemicals. It's far from the oily residue that is removed easily with paint thinner or acetone.
- SAI_Peregrinus 3y agoOven cleaner (Easy-Off heavy duty or similar), in a sealed plastic bag with the item in question, left for 24-48 hours. Rinse thoroughly with tap water, then DI water, then distilled vinegar, then tap water & DI water again. Works to strip cast iron, should work for similar gunk. Obviously wear appropriate PPE (long rubber gloves, follow all warnings on the oven cleaner, work in a well-ventilated area, the MSDS[1] is useful though all instructions should be on the label).

- Eisenstein 3y agoIf the cookware is metal you can use electrolysis. Car battery charger clamped with an electrode to sacrificial metal plate and an electrode to cookware; both hanging apart from each other in a bath of electrolyte made of water + sodium carbonate. Let it work for a day or so in a well ventilated area (it will create hydrogen gas).

- maxerickson 3y agoAmmonia vapor works great on burned on grease if the thing you are cleaning isn't damaged by it. Use it for my burner grates and drip pans, just put them in an enclosed container with some ammonia and let sit for a day or two.
- thsksbd 3y agoPut it in the over and run the clean cycle. It'll get ashed.
- jeffbee 3y agoDepending on what the material is, you can potentially clean it by burning it harder. Set your over to 'clean' and find out.
- bradrn 3y agoThe issue is that ‘any organic residue’ includes any food you might happen to put on it afterwards, if any trace of the solution is left. Or, for that matter, it includes your entire body. This is an exceedingly bad idea unless you enjoy your food bursting into flames, then burning a hole through your stomach if you eat it.
- exmadscientist 3y agoIf you catch it before it's totally incinerated, Tergazyme/Tergajet is the way to go. Otherwise try either Citranox or Alconox (or the 'jet versions for low foaming). If none of those three will touch it, it's probably not cleanable by anything short of piranha-class terrors. If they can touch it but don't get you all the way there, there's probably some combination of detergents and procedures that will do it, but it may take some serious effort to figure that combination out.
- rini17 3y agoMy granny salvaged some burned stainless steel cookware from trash by boiling them in vinegar.
- tomwphillips 3y agoA colleague of mine used it to etch carbon nanotubes, I think. Absolutely horrible stuff.
- refurb 3y agoI always preferred a mixture of KOH and H2O2. Basic solutions of peroxides have less tendency to spontaneously detonate.
