Choosing an oven - Which self-cleaning system should I prefer?

In modern ovens, there are several options for self-cleaning - pyrolysis, catholytic, hydrolysis ... Moreover, in different companies catholytic can be called completely differently. Share your experience, who has what kind of self-cleaning system and how effective are they?

Regarding pyrolysis - the oven is heated to a temperature of about 500 degrees. Impressive. But how safe is it (when buying furniture, they planned an oven under the hob, and it is gas ....). The instructions say not to hang towels, etc. on the oven handle, because it is fire hazardous, that is, the door heats up unambiguously, and nothing is said about the side and rear walls ...

I have a pyrolysis oven. I turn it on once every 1.5-2 months, 3 degrees of intensity, it cleans perfectly. The cleaning process itself lasts from 1 hour to more than 2 hours, depending on the chosen degree. There is a burning smell, but not pungent, as if something was burnt, there is no smoke, with a good exhaust hood, we solve the issue. My oven is at an impressive distance from the hood, and my family members don't notice anything. As for security ... everything is OK with me, because during pyrolysis, the door is automatically locked, I did not experience much heat when I was around, just warmer than usual and that's it. The outer glass of the door does not heat up to high T. After the end of the process, the automatic cooling is switched on. I have a NEFF oven.

Tell me, what have I got? I didn’t know that there are so many different systems
We bought one with rough walls. Do not get dirty. You do not need to wash and clean them. Only if anything drips to the bottom, then wipe it off after baking. Type of cinder and fat itself is somehow cleared from the walls during the baking process. After a year of use (frequent) like new

[Mila007]

I have catalytic, bullshit. If I bought it now, I would choose pyrolysis.

Mila007 You also have catalytic. Yes, the side and back walls are clean, and the bottom, and the top, and the runners?

skids must be removed during pyrolysis

Top, bottom and how are they runners get dirty if grease splashes on them. But rarely and a little this happens .. I clean them (lightly wipe with a damp cloth) after baking. Not a speck after a year of use

Once something leaked downstairs, I don't remember anymore that it was welded tightly. The top splashes perfectly from the grill, aerocrill, and just from cooking something greasy with convection.

[Boo Boo]

Boo Boo, my runners are easily removed, this is provided for by the design, and then they are also easily inserted back. Otherwise, they would peel off during pyrolysis.

I use the grill and convection very often, I agree that greasy splashes fly in all directions, the oven has the same look, and I have neither the time nor the desire to wash it all the time. Pyrolysis is a salvation, when I chose the oven, it was he who was in the first place.
Any contamination, even very heavily burnt fat, smudges, etc., everything burns out and turns into a scanty amount of ash, which can be easily wiped off with a napkin. And the oven is like a store.

In, and the runners can probably be shoved into the dishwasher.
So if there is a possibility, then definitely pyrolysis.

Like Mila007, I also heard about self-cleaning for the first time. Is it (any option) in all new ovens? My whirlpool is all twisted, but unused, because it is in the apartment, and there my granddaughter does not cook. I clean my microwave (inside a stainless steel) until it is new with Amway (I put it on for half an hour and wash it with a cloth, and rinse it with water).I also thought to do with the oven if necessary ... I'll have to read about it in the instructions at my leisure.

Yes, I heard about self-cleaning. Mine is exactly like that. When I bought a year ago, then they told me about it. Only I did not know about so many self-cleaning methods. That's why I asked which one my oven belongs to. In general, honor and praise to the one who invented this!

Heat and steam cleaning

Cleaning the inside of the oven is the most unpleasant task, which can discourage the desire to cook something in it. Fortunately, modern ovens make this work easier, and can even take it over.

The dirt won't stick to her

In order to simplify manual cleaning of the oven as much as possible, manufacturers cover the inner walls of the oven with smooth enamel, devoid of any pores and repelling water and grease. Dirt does not stick to this coating, and, moreover, it is resistant to the acids formed during the heat treatment of fruits and foods with a high sugar content. Such enamels are used in Candy, ARDO, Zanussi ovens (ETC enamel - Easy To Clean), Bosch (GranitEmail). The enamel of the inner cavity of a number of BSH ovens has a characteristic blue color - this is a distinctive feature of the new enamel coatings

I had one like this, everything sticks pretty
Gaggenau enamel oven

An oven with such a coating can simply be wiped with a damp cloth while it is still warm. Under no circumstances should abrasive materials, wire scouring pads or other rough products be used to avoid damaging the enamel.

Catalysis, ecolysis, hydrolysis ...

Oven self-cleaning systems can be divided into low-temperature ones, when fat particles on the wall are decomposed chemically (catalytic method), or with low heating, and high-temperature (pyrolytic), when these particles are simply burned out at a high temperature.

The walls of ovens, which use a catalytic cleaning method, are no longer covered with smooth, but with porous enamel. The pores of such a coating contain particles of a special substance (catalyst), which accelerates the breakdown of long fat molecules into the simplest products - carbon dioxide, water and light organic residues.

The catalytic cleaning process usually starts at a temperature of the order of 140-160 ° C, and proceeds most intensively at 200 ° C. In Bosch-Siemens ovens with ecoClean catalytic coating, the process runs at a higher temperature, about 270 ° C, and is called "ecolysis", which emphasizes the high degree of decomposition of fatty deposits.

Catalytic plates and grease filters are available as accessories on many hotplates and ovens. The panels, unfortunately, cannot be regenerated (however, their resource is quite large, about 300 hours), but the filters can be regularly washed in the dishwasher. It is important to remember one thing: the filter cannot be washed with the dishes! There will be nothing for the dishes from joint washing, but the pores of the filter can become clogged with food debris from the dishes, and it will stop working.

Unlike catalysis and its variety - ecolysis, ovens are cleaned with steam (hydrolysis) at low temperatures. For example, to clean Neff ovens with EasyClean, it is enough to pour water and detergent into the cooled cavity and activate the cleaning function. Hot steam will soften the dirt. After the end of the program, it is enough to wipe the oven and let it dry with the door open.

Several models of AEG-Electrolux ovens have a Cleaning system that requires the use of special sprays. The oven is heated up to a temperature of 90 ° C and held for about 15 minutes, after which an acoustic signal sounds: it's time to apply the spray! The lighting is switched on for 5 minutes (this time should be enough to spray the spray). The time it takes to remove food and spray residues depends on how dirty the oven is and the type of product used.

The cleaning temperature is even lower in Gorenje ovens with the Aqua Clean system. For such cleaning, pour 0.5 liters of ordinary water into the oven baking sheet and leave for half an hour at a temperature of 50 ° C, activating the cleaning program. Then, simply wipe down the inside of the oven, removing any residual dirt, and your oven is ready for new culinary feats.
Burn it down

In contrast to the delicate low-temperature cleaning modes, pyrolysis is the splitting of fat particles at a high temperature (about 500 ° C). In this mode, the oven door is automatically locked as soon as the temperature inside reaches 300 ° C in order to prevent it from being suddenly opened by children. The door can be reopened only after the temperature inside has dropped to 200 ° C. After the end of pyrolysis, the hostess only needs to sweep the ashes out of the oven.

The vapors generated in the oven with such a strong heating are cleaned by passing through a special filter so that unpleasant odors do not form in the kitchen. And yet, sometimes you can hear the opinion that pyrolysis is accompanied by a characteristic odor. It's all about the accuracy of the stove owner. A pyrolytic cleaning system can work wonders, but its possibilities are not endless. If you only clean the oven every six months, odors cannot be avoided. Experts recommend pyrolytic cleaning after every major meal. Then there will be no odors, and the stove will be in perfect order.
Depending on the degree of soiling of the oven, the owner can set the cleaning mode to light, medium or intensive. Until recently, this was the only "degree of freedom" when operating with such an oven. Recently, manufacturers of household appliances have offered new opportunities to owners of their products.
Do you know how often housewives use the oven? Special studies have shown that, for example, in Moscow - from 2 to 4 times a week. And English housewives do it 7-10 times a week, but they mostly cook not meat dishes, but dishes from vegetables, for example, such unimaginable dishes for us as baked cucumbers. To remove light, "vegetable" contaminants from the oven, a comfortable pyrolysis mode was invented, which includes a phase of preliminary firing of the oven cavity. It is used in Gaggenau and other BSH products. The pre-firing is carried out at a low temperature, and, therefore, the energy consumption for the entire cleaning cycle is reduced.

The next stage in the evolution of pyrolysis is associated with the introduction of an additional element into the design of the oven - a catalytic filter with a small heating element of its own. Food residues burn out on the filter, so its temperature is slightly higher than the temperature in the oven. When these residues are burned out, and the temperature of the filter equals the temperature in the cavity, the pyrolysis can be finished. Indeed, why waste electricity?
The problem of automatic control over the residual level of contamination in Whirlpool pyrolytic ovens is solved in a different way. Here a special sensor of the 6th Sense system monitors the concentration of carbon dioxide in the cavity. There is a lot of gas, which means that pollution is still decomposed by the high temperature. The concentration of carbon dioxide began to fall, which means that all fatty contamination has already decayed.

In, and the runners can probably be shoved into the dishwasher.
So if there is a possibility, then definitely pyrolysis.

Girls, the main rationale for removing the guide runners during pyrolysis is only the fact that high-temperature lubricants are burned out, which are applied to movable hinges (in most cases, these are pressed small metal balls). It is for this reason that these most movable telescopic guides cannot be put into the dishwasher. If you burn out or wash out the grease - with any movement of the guides there will be a nasty and loud grinding of metal.
