ᐅ Light damage on white Kallax units – who has experienced this?

gamo52Hello everyone,
I have several white Kallax shelves from Ikea in my living room. I’ve noticed that the white surfaces, especially on the module sides facing the window, develop a yellowish or brownish tint over time. It looks like some kind of light damage or yellowing caused by UV exposure. I’m wondering if this is a known issue and if anyone here has had similar experiences?
Are there any recommendations on how to prevent or at least minimize this? I use the shelves normally, but direct sunlight definitely hits the white surfaces during the day.
I’m also curious whether the material composition of the white Kallax modules makes them prone to this, or if specific environmental factors might be involved. I’ve read that some plastics or coatings can yellow over time, but how much does this apply to Kallax?
Thanks in advance for your feedback!

I can clearly understand what you mean about the yellowing of the white Kallax units. Especially with furniture that has a white laminate or melamine surface, like the Kallax, discoloration from UV light is indeed quite common. The yellowing usually occurs due to UV radiation triggering chemical reactions that gradually alter the material. These changes mainly affect the plastic components of the surface.
In Ikea furniture, the outer finish is often a melamine coating, which is relatively resistant to scratches and moisture but does not fully protect against UV exposure. This means the more direct and prolonged sunlight over days or weeks, the stronger the yellowing can become.
One suggestion: if possible, you could move the furniture slightly away from the window or use curtains or UV-filtering films to reduce direct light exposure. Unfortunately, these kinds of damages are not reversible, as they represent permanent changes in the material.
I’m also curious: how long have your Kallax units been in that location? And are the affected areas exposed to direct sunlight, or is the light diffused/reflected?
This can have a significant impact on how quickly and severely the yellowing develops.

I usually don’t like just putting furniture away or covering it up, but by now I’ve adjusted curtains so direct sunlight doesn’t hit them so strongly.
It’s a bit frustrating because you can’t immediately see that this can happen. That’s why I think it’s good that you brought up this topic here.
Is there anyone here who might have tips on how to reduce or hide yellowing through cleaning or home remedies? Or are the damages really permanent?
I find it interesting to share some thoughts about the material itself.
The white surface of the Kallax is usually a melamine resin-coated particleboard or MDF panel. Melamine resin is durable but sensitive to light—especially UV radiation, which causes chemical aging that results in yellowing or discoloration.
The quality of the coating is also important: some production batches or lines use different additives that provide varying degrees of UV stability. This means that yellowing can vary even between identical models.
Additionally, the location regarding light intensity, humidity, and temperature is a factor. Direct exposure to light has the greatest effect.
Ikea generally does not provide information about UV protection for these surfaces. Therefore, I would recommend preventive measures rather than relying on the materials themselves—such as curtains, UV window film, or occasionally rotating the furniture, as already mentioned.
Has anyone tried using special protective coatings or sprays? In theory, this could protect the surface, but I am not sure how compatible they are with the melamine coating.
