Lemons are a staple in many kitchens. They not only add a fresh touch to dishes and drinks but are also a popular home remedy for cleaning. The citrus fruit is often recommended for cleaning ovens. The acid it contains is said to dissolve grease and baked-on residues and eliminate unpleasant odors. But does the often-praised lemon trick work as well as claimed? 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 level of grime ranges from baked-on splatters to mysterious crusts and grease stains. The weapon to remedy this: a lemon.
The plan is simple: A lemon is halved and placed in a baking dish filled with water. It then goes into the oven. At medium heat, it is supposed to quietly demonstrate its full range of effects. There’s 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 with a cloth is conducted: Could the lemon remove the grime? Indeed, an effect is quickly noticeable: Many residues are much easier to remove. While a magical “one wipe and it’s gone” moment doesn’t occur, the effort required is significantly less than before. It seems the warm acid has greatly softened the dirt. However, extremely baked-on stains still need additional help.

The positive cleaning effect is easy to explain: The reason is the citric acid contained in lemons. It not only helps 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.
