If the cantilever is withdrawn slowly enough, the hydrophobic Si - H surface repels the solution and the cantilever remains almost dry. If small droplets from the solution remain on the Si surface, they are carefully blown away using a high-purity argon stream which avoids severe damage to the cantilever surface and poor results due to irregular etching.
