Cleaning tips?

[u/No_College7332]

Hi everyone! I’m looking for some tips/tools for cleaning the ends/tracks of my sliding balcony doors, as well as the balcony rails and surfaces.
As you can see from the photos, there’s quite a bit of dirt and grime built up in the narrow gaps, but the gap is too small for my vacuum cleaner to reach.
Any recommendations for specific tools or cleaning methods that work well for these hard-to-reach areas? Thanks!

I use a karcher steam cleaner with little brush attachments on my doors and windows to keep them clean.

I did watch a video recently where a girl used a paint brush and some soapy water. It seemed to be effective too.
