In Dutch for applications (toepassingen):

Schoonmaken van binnenband (bijvoorbeeld fiets) alvorens solutie (lijm) aan te brengen; dit werkt beter dan schuren omdat eventueel vuil wordt opgelost en afgevoerd en niet wordt uitgesmeerd

translation; for cleaning inner tube (ie bicycle) before applying the
cement (glue); this works better than sanding because dirt is disolved
and removed instead of smeared out.
I agree with that.

Dirt is mostly minerals and does not dissolve. Put some dirt in a
beaker of water, shake well, let settle and see what's left. It's
probably the same dirt you put into the beaker.

My guess(tm) is that Wasbenzine is just water and an organic solvent
mix. The water breaks loose the dirt, while the solvent removes any
oils and mold release. The mold release used with rubber is probably
silicone based, which according to Wikipedia, might be water soluble:
