Is tacky-roller or polymer roller cleaning the best for all applications?
Tacky-roller or polymer roller will remove more contamination than non-contact cleaning. Dust (including lint, hair, clothing fibres and other airborne contamination) on a substrate can only be removed by moving air down as far as the “boundary layer”. This is a very thin layer immediately adjacent to the surface where air velocity is significantly reduced, dramatically reducing the cleaning ability of moving air. Consider a dusty TV screen – blowing on it (non-contact) will not remove all the contamination, it will normally require a soft cloth (contact) to clean it properly. More information on the boundary layer can be found on this NASA web page.
