Grout joints between the tiles darken over time and become hard to clean. Scrubbing with a brush and chlorine cleaner is laborious and smells harsh. Hot micro steam loosens dirt and deposits out of the joint, entirely without chemicals and without a brush. This page shows step by step how it works.
A thin jet of steam at around 180 °C loosens dirt and deposits from the grout joint, without a brush or chlorine, and reduces germs through heat (proven: CDC, Sexton 2011).
Grout joints are rough and slightly absorbent. They take up dirt, grease and soap residue and darken over time. With a brush you barely reach the depth of the joint.
Harsh grout and mould cleaners often contain chlorine and irritant substances. You have to ventilate and wear gloves. Such substances are considered contact allergens. [Source: DermNet] And what you rinse away ends up in the waters via the wastewater. [Source: UBA]
So the cleaning stays laborious: scrub, rinse, ventilate. The harsh smell often still lingers in the room when the joint has long been clean.
The rough joint sits lower than the tile. Scrubbing from above only removes part of the dirt.

What you rinse away ends up in the waters via the wastewater.
The thin steam jet, around 180 °C hot, goes right into the joint. The heat loosens grease, dirt and deposits, which can then be wiped away.
The heat also reduces germs in the joint. [Source: CDC] Because the steam contains little water, the surface stays only slightly damp. How the heat works in detail is explained in the micro steam overview.
Without scrubbing, without chlorine. One device, the narrow grout nozzle, hot steam.
Three ways to a clean joint. The difference lies in the effort and in what stays behind.
| Hot micro steam | Brush & chlorine cleaner | Home remedies (baking soda & vinegar) | |
|---|---|---|---|
| How it works | Heat loosens dirt | Chlorine loosens, brush scrubs | Reaction, then scrubbing |
| Reaches into the joint | yes, thin steam jet | only from above | only from above |
| Harsh fumes | none, just water vapour | yes, ventilation needed | none |
| Germs through heat | yes, reduced through heat | no | no |
| Residues / wastewater | none, water evaporates | Chlorine goes into the wastewater | Residues rinse into the wastewater |
| Physical effort | low | high, lots of scrubbing | high, lots of scrubbing |

Moist heat reduces microorganisms (CDC).

Frequently asked questions
The hot steam loosens dirt and deposits out of the joint and reduces germs through the heat. Whether the joint stays clear for good depends on the humidity in the room. Steam is no miracle cure against the cause.
For tile grout joints in the bathroom and kitchen. Steam natural stone carefully depending on its sealing and test on a small spot beforehand.
Yes. Only steam and wipe silicone, don't scrub. That way the joint stays intact and still gets clean.
As a rule, no. For tile grout joints, hot steam from pure tap water is enough; the heat does the work.
Only slightly damp. The steam contains little water, the surface dries off quickly again.
With the same device you can also clean the bathroom, oven and vehicle interior. At the free demonstration we show it on your own surfaces.
