Make sliding balcony door operable

Hello dear ones,
our sliding door is running a bit stiff. Of course, from time to time it is necessary to clean the sliding system, which is scheduled for next week. Have you found an ideal product to lubricate/spray the tracks of the sliding door?
Many oils or greases tend to become sticky or resinous. I was thinking of products like Caramba, WD 40, or similar. Do you have any tips?

Our door fitter sprayed silicone when adjusting the windows afterwards - however, I did not find the effect to be particularly long-lasting.

I have had good experiences with oil from Ballistol during my time as a carpenter. Does not become resinous, lubricates well, and smells good.

At work, we lubricate everything with Ballistol and WD40. Although the latter is already a brilliant product. Outside, I always find the problem of dust and dirt. So if you use a dose of WD40 or Ballistol, the problem may be that it gets more and more dirty, which in turn requires more cleaning and ultimately more lubrication again. One likes to lubricate keys and keyholes with graphite. I think that could also be worth considering? A dry lubricant that does not bind and trap the dust and dirt that is just out there outside. So that could be something to think about.

Graphite hmm.. I am unsure. Need to research further.

Hi,

Graphite hmm.

Besides graphite, Aunt W. also reports molybdenum disulfide as a solid lubricant. Space travel also requires a lot of dry lubrication, but NASA probably wouldn't help you. By the way, at Aunt’s place there is a small book on the bottom shelf titled "FAG-Ball Bearings, Lubrication of Rolling Bearings, p.33 (PDF; 989 kB)," maybe you'll find some information there that will help you further.
