In conversation with my colleague, I said:
Comment tu fais pour enlever efficacement les poussières qui se trouvent accumulées sur la surface du clavier ?
When I use the reflexive "se trouver" in the sense of "se situer", I usually have a preposition immediately follow "se trouver":
Comment tu fais pour enlever efficacement les poussières qui se trouvent sur la surface du clavier ?
But I spontaneously thought of adding the idea of "accumulées" into the sentence somehow, leading to this turn of phrase: "se trouvent accumulées sur". I wonder if this construction is acceptable too?
