In silanization, how to clean kerosene from glass surface completely?

I'm doing some silanization experiments using kerosene to dilute the silan solution. For instance I use a mixture of 10% silan in kerosene. However, after several tests I realized that I cannot completely clean the surface from the remaining kerosene after silanization, and in fact the contact angle that I read is more related to kerosene rather than silan. After silanization, I wash the glass surface with a stream of water and then put the surface in a bottle of acetone and then shake the bottle for 20 sec to clean the kerosene, but apparently it is not enough.
What is the most effective way to get rid of the remaining kerosene on the glass surface?
