Clean the back wall in the oven

When cleaning the back wall in the oven, manual action is required in older and simple devices. Modern models have self-cleaning systems that exploit physical laws and special materials. But also with the manual procedure with home remedies the physics helps to reduce the wiping work.

Manual cleaning methods

For the contamination of a back wall in the oven, the combination of fats and heat is responsible. When cleaning the burned traces can be partially beaten with the "own weapons":

oven cleaners

The relatively aggressive chemical degreaser is sprayed on according to the manufacturer's instructions and wiped after exposure with a cloth. The products are expensive and harmful to the environment.

lemon juice

On a baking sheet or heat-resistant container, place eight to ten spoonfuls (100 milliliters) of lemon juice diluted with the same amount of water into the cold oven. The oven is turned on and heated to about 120 degrees. When the juice has evaporated, the oven is opened. As soon as the internal heat allows the insertion of a damp cloth, the inner walls and heating rods are wiped off.

Soda / washing soda

Sodium carbonate is mixed with water to an optically saturated milky cleaning liquid. With a spray bottle, the solution is sprayed generously into the cold oven interior. After a two-hour exposure time, rinse with clean water and pick up any dissolved lumps of dirt with a cloth.

Self-cleaning systems

The manufacturers of ovens offer under different names self-cleaning systems in their devices. All work in one of the following three physical approaches:


Strictly speaking, catalysis is more about avoiding dirt than cleaning. Special ceramic surfaces in the oven interior bind grease spatter, which oxidizes the grease during the following heating cycle (200 degrees Celsius). This results in non-toxic carbon dioxide and water.


During pyrolysis, the fat is "burned away" at high temperature (500 degrees Celsius). In addition to fats, protein and starch residues also dissolve. The interior must be equipped with pyrolysis-resistant materials. The process lasting up to several hours consumes a lot of power.


During hydrolysis, the dirt is "steamed" with water vapor. The process dissolves encrustations and has only a limited fat-dissolving effect. By adding special cleaning agents, the cleaning effect can be increased.

Tips & Tricks

If you have an oven with a self-cleaning system, use manual intermediate cleaning according to the manufacturer's instructions. Wrong means and methods quickly damage the surfaces and the physical requirement for automatic cleaning capabilities.
