A microfiber cloth I think is the best solution, if you happen to have one. Unless you are, or are around hair product type people, a damp/dry cloth/napkin/paper towel etc. should be all you ever need. But you shouldn't be afraid of windex and such if the need arises. If you want the driest read of your life, check out the white papers from Corning....

Household Solvent Testing
Similar to environmental testing however more specific to device end-use environment is testing of common chemicals towhich
the display may become exposed. Display end-users will handle and treat the display surface in varying manners and without
regard for what detrimental effects may be imparted.Thus, rigorous solvent testing is required for all proposed display products.
Specifically addressing interest in Corning Gorilla Glass and its easy-to-clean coating for the mobile device community,household
solvents were selected based on those most likely for the device to be exposed to during use and in end-user efforts to clean the
device. Table 3 lists numerous household materials and solvents selected for testing, again using the maximum 10? drop
in post-exposure, static water contact angle as the pass/fail criteria. Each material was tested after exposure to the material/solvent
for a 24 hour period, whether the material was smeared onto the surface without removal or soaked in solution. Specific values for
resulting water contact angles are listed, with the coating passing all tests.
