How can I remove excess flux?

I am working on my MMC for the Tesla coil and I just soldered the caps in series.
There is still a lot of greasy flux on the plexiglas and I don’t know how to remove it without damaging the caps. So far I’ve just been using dry paper towels.
Is there a household chemical?

Alcohol should work OK; I use IPA but such as rubbing alcohol or methylated spirits etc. should also do the job.
