Bright yellow, wonderfully juicy, and super sour: Lemons are true all-rounders in the kitchen. With their delightful note, they give many dishes a certain twist. But they are not only good on the plate—lemons also shine when it comes to cleaning the oven or removing burnt-on food residues. myHOMEBOOK tested using a lemon to clean the oven.
The oven is one of those kitchen appliances that is frequently used but not often cleaned. Grease and burnt-on residues are often stubborn and make maintenance tedious. For those who, for ecological and health reasons, do not want to rely on conventional cleaners, a look into the fruit basket is worthwhile. Lemons are said to be surprisingly effective when it comes to cleaning the oven. It’s no wonder they have a permanent place in grandma’s household hacks. But what’s the truth? myHOMEBOOK put it to the test.
The Preparation
The oven—usually a stage for crispy homemade pizza and roasted vegetables—has turned into a small battlefield over several days. The degree of contamination ranges from burnt splatters to mysterious crusts and grease stains. The weapon that is supposed to help: a lemon.
The plan is simple: A lemon is halved and placed in a baking dish filled with water. Then it goes into the oven. At medium heat, it is supposed to quietly demonstrate its full range of effects. There is anticipation as the heat unfolds.

The First Impression
After just a few minutes, a gentle, fresh scent spreads through the kitchen, almost creating a bit of a Mediterranean flair. The cleaning attempt suddenly feels much less like a chore.
It takes about 30 minutes before the oven is turned off and the door is opened. A small cloud of steam escapes—warm, lemony, promising. A direct test is done with a cloth: Could the lemon loosen the dirt? Indeed, an effect is quickly noticeable: Many residues can be removed much more easily. Although a magical “one wipe and it’s all gone” moment doesn’t occur, the effort required is significantly less than before. It seems as if the impurities have been greatly softened by the warm acid. However, extremely burnt-on stains still need additional help.
Powerhouse Lemon
The positive cleaning effect is easy to explain: The reason is the citric acid contained in lemons. It not only helps to break down fat structures but can also effectively dissolve deposits like lime when combined with heat. Additionally, the ingredients have a mild antibacterial effect and help neutralize odors—especially in the oven.
