Four anti-mould agents in comparison

12.6.2025

Translation: machine translated

The grouting in my bathroom paints a bleak picture: the mould has come out of the grouting, into the grouting. I took the black gaps as an opportunity to compare four anti-mould agents.

Sometimes product comparisons don't work the way I think they should. This is one such case. The anti-mould cleaning products tested work. You can go for it. For a little more meat on the bone, read on...

My own mould culture

No windows, a clogged ventilation, a shower and a tumble dryer. This also means a constantly humid, warm climate. Only a petri dish provides a better breeding ground for mould. The black grouting in the bathroom has been bothering me for weeks, and I don't stand a chance with normal cleaning products. Special products are needed. Specifically: the four best-selling products at Galaxus.

The Glutoclean product is the only one that does not contain chlorine. It relies on hydrogen peroxide. This is the same agent used to bleach hair.

Chlorine in cleaning products is considered problematic because it poses risks to health and the environment. Cleaning can produce chlorine vapours that irritate the eyes, skin and respiratory tract - especially in poorly ventilated rooms. If chlorine comes into contact with other cleaning agents such as acids or ammonia, toxic chlorine gas can be produced. In addition, many chlorine-containing compounds are poorly biodegradable and pollute water bodies. Nevertheless, the bleaching and killing properties of chlorine make it the ideal cleaning agent for discoloured grout when used infrequently.

The test that wasn't a test

I applied the products according to the instructions, left them to work in and then cleaned the grout with a damp sponge and the grout cleaner. With the following result

The products with chlorine were particularly effective. Glutoclean with hydrogen peroxide was a little less effective at first. It takes longer to work, but then achieves similar results to the other three products, because: I couldn't find any big differences in the products with chlorine. All of them removed the black mould quite reliably. This is in line with a test conducted by Ktipp (paywall).

Nevertheless, I wouldn't completely rule Glutoclean out of the running. In the Ktipp test, the product performed best among the chlorine-free cleaners. With chlorine, you have to be very careful not to inhale the vapours. In my closed bathroom, the ventilation was constantly running and I ventilated the whole flat to be on the safe side. You don't have that risk with chlorine-free cleaning products. Gloves and safety goggles are definitely advisable, as all cleaning products can attack the skin.

Conclusion

All anti-mould agents work, they clean away the fungi and bleach the stubborn areas so that you can hardly see the fungus. I hope they were only used this one time, as from now on I will remove the breeding ground for the spores by cleaning the ventilation and using a dehumidifier.

A small spray bottle would have sufficed for cleaning. The products tested are all between 5 and 7.5 decilitres. I could use this to remove mould from an entire indoor swimming pool with an Olympic pool. Unfortunately, there are no smaller units. If you keep getting mould, you urgently need help from a specialist and not anti-mould agents.

When I flew the family nest over 15 years ago, I suddenly had to cook for myself. But it wasn’t long until this necessity became a virtue. Today, rattling those pots and pans is a fundamental part of my life. I’m a true foodie and devour everything from junk food to star-awarded cuisine. Literally. I eat way too fast.
