Silicon spray can cause galling at a metal to metal sliding contact. It is famous for destroying air guns.
You can get small amounts of slideway oil, no need to get the whole 5 litres.

GT85 Teflon spray all day long for cleaning metal to metal surface slides.
I used to run automated equipment from Heidelberg machinery and they weren't wrong on that one.

Silicon spray! ..... Noooooo!!.
