Canon 70-200mm F/2.8 L Mk1 Internal Lens Cleaning Support?

[t3hree6ty]

Hello!, I'm new to the forum and I was wondering if Canon has a service for cleaning the interior lenses of my Canon 70-200mm 2.8 L Mk1? I saw the services listed for external cleaning and internal checks but no internal cleaning. I was hoping to find that kind of service since mine has accumulated quite a bit of dust and would like to get a reputable way to clean it other than doing it myself.

I am sure you can always find people to take your money, I would not get to worked up about it:

Greetings,

The mkI is still under support until May of 2026.

What is inside it? Is it just dust or is it fungus? I doubt Canon will clean it if it has fungus and if it is dust and does not show in your photos forget it.
