ᐅ Why is the surface of the Kallax so prone to fingerprints?

I have a specific question that has been on my mind for a while: Why is the surface of the IKEA Kallax shelf so prone to fingerprints? I’ve noticed that even after brief contact, the surface becomes visibly smudged or even shows slightly glossy spots that are difficult to wipe off. I’m wondering if this is due to the material, the paint, or the particular surface treatment. Could it be related to some kind of surface tension or a dirt-attracting effect? Are there certain paint or coating formulations that tend to highlight fingerprints? I use the shelf in my home office, and the visible fingerprints really bother me, especially because I like the furniture a lot. Maybe someone knows more precisely why this happens, or even if there’s a way to prevent or reduce it without having to repaint the shelf.

The surface of the Kallax is usually melamine-coated, which is durable, but fingerprints tend to show up quickly on smooth surfaces. The only way to prevent this is regular wiping with a damp cloth or using special microfiber cloths.

This is an important point, and I would like to explain it in more technical terms: The melamine resin coating applied to the chipboard panels of the Kallax shelving unit is generally quite scratch-resistant and easy to maintain. However, the surface is typically smooth and slightly glossy, which causes oils and fats from fingertips to adhere particularly well, making visible prints.

This effect is intensified by the surface energy of the material, which essentially “attracts” certain contaminants. The slightly elevated surface tension causes minute traces of grease to form thin films that are especially noticeable when light hits them.

A matte or textured surface would better conceal fingerprints, but the typical Kallax finish tends to be smooth and somewhat glossy.

For everyday care, specialized cleaners that dissolve grease or microfiber cloths can be effective, as they pick up particles instead of just spreading them around.

I’m curious, is the shelving unit located in a high-traffic area in your home? Sometimes humidity or dust particles can worsen the effect.

Yes, the shelf is in my home office, which I use daily. I touch the shelf quite often—not only when organizing documents but also occasionally to set my cup down on it.

The humidity level is fairly normal, but because of a nearby radiator, the air can become quite dry at times. There is also some dust, but I clean the shelf regularly. I’ve noticed that the surface, especially around the corners and edges, tends to show smudges more frequently.

I’m wondering if the combination of the smooth melamine surface and static electricity caused by the dry air might be contributing to this?

This would align with my observation that the fingerprints might remain visible not only due to the natural oils from the skin but possibly also because of fine dust particles.

From your experience, is there really a connection between static electricity and the visibility of fingerprints on surfaces like this? And if so, how could this be prevented?

From your perspective, is there actually a connection between electrostatic charging and the visibility of fingerprints on such surfaces?

Yes, there is indeed a measurable connection. Melamine resin surfaces, like those on Kallax, tend to become electrostatically charged due to their material properties. In dry environments, this charge is intensified by the lack of humidity, as moisture acts as a natural charge neutralizer.

This electrostatic charge attracts dust and grease particles, which settle on the surface. While fingerprints are mainly caused by skin oils, the charge increases the accumulation of dust, making the prints more visible.

In practice, it is recommended not only to clean regularly but also to slightly humidify the indoor air, for example with a humidifier. Additionally, antistatic cleaning agents or special cloths can help neutralize the surface charge.

A general change to a matte finish is unfortunately not possible for Kallax, as it is a manufacturing characteristic. However, targeted care can significantly reduce the issue.

I can definitely confirm that and would like to add the following: The surface texture is very important. Smooth, non-porous coatings, as commonly found on Kallax, make fingerprints more visible compared to textured or matte finishes, for example.

The natural oils from the skin spread very thinly upon contact but remain visible because the light reflects differently off the smooth surface. Additionally, repeated touching leads to oil buildup that cannot be easily removed without proper cleaning.

A practical tip for everyday care: Low-concentration rubbing alcohol or specialized furniture cleaners are effective and do not damage the melamine surface. Using a good cloth or microfiber towel also helps prevent scratches. So fingerprints on such surfaces are not a product flaw but a natural characteristic of the material.

Finally, I would recommend occasionally wiping the shelf with a soft cloth in less frequently touched areas. This way, you avoid spending unnecessary time on constant cleaning.
