no. because the coating is mixed with the silica mix upon creation of the glass. use alcohol if you want.

if the coating wears off, it means that the filter is cheap, coating was just painted on top

after I rub the top surface with thumbprint to clean it, theres a slight different color at that part. I realised my mistake to clean it with normal cloth, so I clean it with lenspen. but the spot is still there.

Is my filer fake? bought at RM175 for Hoya Pro1Digital 67mm.
