Even if it has completely dried off, there is still a possibility of residue from the glass cleaner.
There is something further you could try, and people may think I am crazy for this but it does work if done correctly.
Use the disassembly guide to take the DSL apart, then very carefully, in clean water only, wash/rinse the individual parts. Leave them disassembled for a full day or two, ensure they are totally, totally dry. Put it back together only after they are completely dry.
I have done this with a laptop that had a full beer tipped into it. Contrary to popular belief, pure water does not conduct electricity - it is the contaminants in the water which facilitate conduction. Turning the machine on while it has the moisture and contaminants in it can destroy components. So the best solution to any water - accidental or not - is to dry it completely, then clean out any residue or contamination, before reassembly and operation.
Good luck.

p.s. the stylus holder is a plastic 'tube' that is open down its entire length on one side. It's held to the lower case half by two screws, but it is in no way sealed. There are effectively openings the entire length of the stylus on either side where the stylus holder rests against the case half.
