Which oven cleaning is better: hydrolysis, catalytic, pyrolytic?


Today, there are ovens with built-in clean­ing — pyrolyt­ic, cat­alyt­ic or hydrol­y­sis. Each type of clean­ing involves its own prin­ci­ple of oper­a­tion, has pos­i­tive and neg­a­tive sides. After ana­lyz­ing them, every­one can decide for them­selves which oven clean­ing is bet­ter.

hydrolysis method

It was also used to clean the first gas ovens. This is the sim­plest, but quite effec­tive way to clean the inside of the oven from dirt. Some mod­els of ovens have built-in hydrol­y­sis sys­tems:

  • Aqua­Clean. Works at a tem­per­a­ture of 50 °C. It is pro­posed to pour 0.5 liters of water or a gen­tle deter­gent into a spe­cial con­tain­er, after which you can close the door and wait for a click indi­cat­ing the end of clean­ing. As a rule, it will take about 30 min­utes.
  • clean­ing. It will require pre­heat­ing the oven to 90 ° C. Oven pro­tec­tion spray is used instead of water. With this tool, it is nec­es­sary to process the inner walls of the oven after the door opens with a click. Clean­ing takes 15 min­utes.

Clean­ing is car­ried out with­in half an hour. Water is first poured into a spe­cial­ly pro­vid­ed round recess at the bot­tom of the oven, in some cas­es gel is also added to it to cre­ate steam. When the oven heats up, the water evap­o­rates and acts on the fat­ty deposits on the inner walls. So, they soft­en and enter the pan.

Cleaning the oven

After the clean­ing process is com­plet­ed, it is required to remove all food residues with a nap­kin.

Hydrol­y­sis clean­ing does not apply to auto­mat­ic meth­ods, since man­u­al labor is not exclud­ed when using it, how­ev­er, it still makes the work eas­i­er for the host­ess, as it helps to quick­ly and effort­less­ly remove fresh grease stains. If they are already very dry, you can’t do with­out treat­ing them with a clean­ing agent and intense rub­bing with a sponge.

Advan­tages of hydrol­y­sis:

  • Low cost of the clean­ing process — there is no need to spend mon­ey on expen­sive deter­gents and use a lot of elec­tric­i­ty, as the process works at low tem­per­a­tures.
  • Facil­i­tate the work of the host­ess.
  • Safe­ty — dur­ing clean­ing, the doors do not over­heat.

Minus­es hydrol­y­sis:

  • After the clean­ing process, some impu­ri­ties remain that must be removed man­u­al­ly.
  • Does not remove old stains.
  • Clean­ing is only done when the oven has com­plete­ly cooled down. Do not turn it on imme­di­ate­ly after cook­ing.

catalytic method

The side walls of oven mod­els with such clean­ing are cov­ered with a spe­cial enam­el, rough to the touch. The pro­vid­ed pores con­tain a spe­cial com­po­si­tion, which, when fats enter them, decom­pos­es them into water, car­bon and organ­ic residues.

Clean­ing is car­ried out dur­ing cook­ing, which elim­i­nates the inclu­sion of the oven specif­i­cal­ly for this process.

The oven bot­tom and doors are not pro­tect­ed and will have to be cleaned by hand. This is because the pro­tec­tive coat­ing is very sus­cep­ti­ble to sug­ar and dairy prod­ucts, which destroy the enam­el. And when bak­ing sweets, their fill­ing very often leaks to the bot­tom of the oven.

Decom­po­si­tion of con­t­a­m­i­nants occurs at rel­a­tive­ly low tem­per­a­tures:

  • if inside the oven is not very dirty, then it will be enough to heat it up to 140 ° C;
  • with strong fat deposits on the walls of the oven, expo­sure to high­er tem­per­a­tures may be nec­es­sary, but they are not high­er than 250 ° C.

After cat­alyt­ic clean­ing, you only need to wipe off the remain­ing dirt with a wet cloth.

Cleaning the oven

The inter­nal sur­faces of ovens from dif­fer­ent com­pa­nies do not dif­fer in the qual­i­ty of clean­ing, but some of them may have a grease fil­ter. It is designed for reusable use — some­times its life can last the entire peri­od of oper­a­tion of the oven. Once every 100 clean­ing appli­ca­tions, it should be washed under run­ning water or in a dish­wash­er, but all dish­es and food debris must be removed from it, oth­er­wise they will clog into the fil­ter and it will stop work­ing.

Advan­tages of cat­alyt­ic clean­ing:

  • No major elec­tric­i­ty and clean­ing costs.
  • Clean­ing occurs dur­ing food prepa­ra­tion and does not need to be super­vised.
  • The cat­alyt­ic method is used not only on elec­tric, but also on gas ovens.

Cons of the method:

  • The enam­el on the inner sur­faces of the cab­i­net los­es its prop­er­ties after four or five years, and the pan­els with it have to be changed. Know­ing this, you need to choose mod­els of ovens with dou­ble-sided pan­els — when the enam­el is worn on one side, they can be rearranged.
  • The bot­tom of the oven and the door will have to be cleaned by hand, to facil­i­tate clean­ing, you should choose a door with the least num­ber of joints and recess­es.
  • Strong con­t­a­m­i­na­tion does not go away in one clean­ing; to elim­i­nate them, you will need to repeat the process again.

pyrolytic method

This is the most effec­tive way to clean the oven, but also the most aggres­sive, and its action cap­tures all the inter­nal sur­faces of the oven. With it, all fat­ty con­t­a­m­i­nants are burned, which become ash­es and set­tle at the bot­tom of the oven. They are eas­i­ly removed with a reg­u­lar kitchen nap­kin.

Pyrolyt­ic clean­ing is car­ried out at high tem­per­a­tures, up to 500 °C. So, for safe­ty rea­sons, in mod­els with such a sys­tem, an auto-lock is pro­vid­ed in the doors, which opens the cab­i­net door only after the oven has cooled down to 200 ° C. In some mod­els, this clean­ing can take place at a tem­per­a­ture of 300 ° C, since they have a mul­ti-lev­el sys­tem. With small pol­lu­tion in this case, a gen­tle mode is used.

Pyrolytic oven cleaning

Pyrol­y­sis is car­ried out with a high con­sump­tion of elec­tric­i­ty, so the oven with it requires a pow­er cable that can with­stand up to 6 kW.

Advan­tages of pyrol­y­sis:

  • There is no need to con­stant­ly emp­ty the oven from trays and grates before clean­ing.
  • Ovens with such a sys­tem are made of high qual­i­ty steel.
  • The most effec­tive method of all of the above, after which no pol­lu­tion remains.

Cons of the process:

  • The built-in pyrolyt­ic sys­tem is reflect­ed in the cost of the oven, increas­ing its price.
  • Clean­ing is car­ried out after cook­ing, and since for its effec­tive­ness it is nec­es­sary to heat the oven to very high tem­per­a­tures, impres­sive elec­tric­i­ty bills will come.
  • Pyrol­y­sis is accom­pa­nied by an unpleas­ant odor, so it is imper­a­tive to pro­vide for the instal­la­tion of a pow­er­ful hood over such an oven.
  • The oven door gets very hot. Dur­ing the clean­ing mode, it is bet­ter that no one is in the kitchen so as not to acci­den­tal­ly burn your­self.

You can clear­ly see the effect of all the described meth­ods for clean­ing ovens in the video, which dis­cuss­es some mod­els of ovens from Elec­trolux:

Which of the above sys­tems is best suit­ed for a par­tic­u­lar hous­ing, it is impos­si­ble to say for sure, since all of them have their pros and cons when oper­at­ing the oven. The appro­pri­ate option should be cho­sen based on per­son­al require­ments for the instal­la­tion and main­te­nance of mod­els with built-in clean­ing.
