Reading time: 2 minutes

Truth and fiction

Cleaning certainly is not one of our favorite occupations. But there’s no way around it. And it’s nice to have everything sparkling and shiny in the end. Fortunately there is a lot of advice to be found online for quicker and better cleaning, leaving time for other things and still getting the desired results. But are these tips really as helpful as we would like to believe? Or is the remedy worse than the illness? We have sought out cleaning myths about glass-ceramic cooking surfaces and have put them to the test.

Dishwasher tabs for cleaning

Dishwasher tabs are meant for cleaning dishes and silverware in a dishwasher. Some do-it-yourself cleaning advisers have hit on the idea that such a tab could clean glass-ceramic cooking surfaces. The common suggestion: “Soften the tab with water until it it becomes pasty. Then wipe this paste onto the Ceran cooktop. Allow to act for a short time and wipe off with a moist cloth. Now just rub the Ceran cooktop dry with another cloth”.

With all due respect to the advisers’ spirit of discovery: do not follow this advice under any circumstances. The tensides in the dishwashing tabs can lead to chemical reactions with the glass-ceramic. The bitter consequence: These reactions can lead to unseemly stains, which cannot be removed after continued cooking operations.

Lemon kills germs and smells fresh

Another home-remedy legend involves lemon juice. Lemon juice is supposedly a cleaning agent that ensures a sunny shine and a fresh aroma in the entire kitchen. Just rub it onto the cooktop, allow to act a moment, and wipe off with a cloth and clean water. Moreover, the acid in lemon juice inhibits germs, which is very useful for a surface on which food is prepared.

It is correct that lemon juice has a decalcifying effect. However, there have been no proven cleaning effects for soiling. But if you do want to use lemon juice for your cleaning then use it only on the cold cooktop and remove it entirely immediately afterward by moist wiping and rubbing dry.

Toothpaste for cleaning and polishing away scratches

Toothpaste constantly finds its way off the toothbrush and into the cleaning bucket. For instance, stubborn stains are supposedly easily removed from glass-ceramic cooktops with toothpaste. Legend has it that toothpaste contains abrasive particles which are not too sharp. A soft cloth is used to rub some toothpaste onto the spot to be cleaned. Toothpaste is furthermore reputed to polish away scratches in glass-ceramic cooktops. Just rub in and then polish with a soft cloth.

The truth is that scratches can unfortunately not be polished out of glass-ceramic. However, they exert no influence on the stability of the cooktop or on the act of cooking itself. Nevertheless, we put the toothpaste myth to the test in our laboratory and could not verify a cleaning effect.
