Woll titanium coated pans

As we all know, if you allow oil to burn in a Woll pan it ceases utterly to be non-stick. I have discovered an effective way to clean burned-on oil from a Woll pan and all it needs is an electric oven with a 250 degree self cleansing programme.

First of all, switch the oven on, set it for 250 degrees Centigrade and allow it perhaps 15 or 20 minutes to reach that temperature. Meanwhile, wash the pan with washing-up liquid and an ordinary plastic pan scrubber to remove as much of the burned on oil as you can.

Remove the plastic handle from the pan and place the pan in the hot oven. Leave the pan in the oven for an hour. Then switch the oven off and allow it to cool. When the pan is cool enough to be handled with bare hands, give it another wash with washing-up liquid and the plastic pan scrubber.

After this treatment, you will find the non-stick characteristics of the pan almost completely restored.

You are getting pretty close to dangerous temperatures. DuPont says, "The recommended maximum use temperature for cookware with Teflon nonstick coating is 500F (260C)." (link)

I wouldn't get Teflon anywhere near those maximum temperatures without some food or liquid in the utensil.

Just noting, your self clean cycle may be stated as 250C but how accurate is that? And also, different coatings have different maximum temperatures. I have no idea what material your Woll uses. Maybe it's good to 250C, maybe not, and your oven may go higher than stated.


By the way, I'm just amazed with self cleaning ovens. My Wolf electric convection oven self cleans at 500F (they say) and a 4 hour cleaning cycle which I'm sure includes up to maybe 2 hours of cool down. Recently I had neglected cleaning my oven and there was baked on stuff all over the place, enough that I know I was insulting my fine oven, but I went ahead and removed the racks and ran it through the cleaning cycle, and when I opened the door I was amazed so see practically nothing except some grey powder. Still being lazy and now in a hurry I just replaced the racks and cooked dinner.

This self cleaning is really great! All these years I had never known that all my hours with my head stuck in an oven with Easy Off could have been avoided by getting a good stove. And convection? If I had known how valuable convection cooking is I would have bought a convection oven decades ago.

Woll Titanium Coated Pans

Hi Gregg,

I think you may be confusing two different things here.

The Woll pans to which I referred are coated in titanium - that's a metal. No 'Teflon' is used on these pans.

Du Pont's 'Teflon' is a plastic (probably PTFE) and as such a totally different product.

Yes I guess I was confused. I never heard of metal non-stick coatings except for cast iron.

If the manufacturer says they can get that hot then you're good to go.

I'm still blown away with the auto-clean feature in my Wolf convection oven. Last week the oven was really horribly messy, one cleaning cycle and it wasn't even worth the effort to clean out what was left. If I get in the mood I'll wipe it down with a damp rag to finish the job.

I can save my Easy Off for cleaning balky pans.

you are not confused.

"Woll cookware uses the tradition PTFE in our diamond and titanium
reinforced nonstick cooking surfaces."

that's what their customer service had to say in July 2013.

the Woll pans are not titanium. they are aluminum with a sputtered titanium coating on the interior.

Swiss Diamond says they use real diamonds and PTFE.

the sputtering produces a sandpaper like surface, the voids are filled in with PTFE aka Teflon.

the sputtering "high points" are supposed to "protect" the softer PTFE from being scraped / damaged.

your mileage may vary.

Sounds like an interesting cooking surface.

In that case, according to DuPont Teflon/PTFE should not be heated past 260C, and the OP's stove self cleans at 250C so that's a pretty narrow safety band.

I think it's each person's call whether they would want to do that. Particularly if you don't know how accurate the oven's self clean temperature is measured.

While I recognize all ovens can be different, a temperature of 250C is not a self-cleaning temperature. It's barely hot enough to cook pizza. Typically, a SC oven on the clean cycle runs at around 900F/500C

yes, 250'C is not self cleaning.

not to mention that every self-cleaning oven I've encountered in USA and Germany locks the door once the temp gets to about 300'F/150'C - so the whole idea is rather suspect.

250C = 482F

I roast chicken at 450 and preheat to 500 for no-knead bread.

But there's no way I'd put any coated nonstick cookware in an oven that hot.

I just called Wolf and they told me my oven rises to about 850F before shutting off the heating elements and probably rises another 50 degrees or so before it begins cooling off.

So the answer she gave me is Wolf cleans at a maximum of 900F. Quite enough to destroy practically anything. And in fact that's why you have to remove the stainless steel racks, because the high heat would discolor them otherwise.
