I would agree w/ the trim recommendations...but here are some tips on how to remove latex caulk:
First, test to see how well it's actually sticking. It may be easy to scrape it off. Take a plastic scraper and try to lift it at the edges of the joint. Do not use a metal scraper...it will damage the finish on the floor. If that doesn't work, you'll need to use a solvent of some kind. Start mild with a citrus-based paint stripper. Apply VERY CAREFULLY to the caulk only, trying to avoid the wood flooring. Let it sit for a few minutes, then use that plastic scraper again. If that doesn't work, you may have to take mineral spirits to it, but that would be a last resort, as mineral spirits will damage the finish on the wood floor.
Once you've gotten most of it up, clean with denatured alcohol. If you re-caulk, follow the advice of using painter's tape to get a clean edge. You may consider using a beading tool (found at most hardware stores) instead of your finger to get a nice, smooth finish. Or, we've found that damp foam paint brushes work really well to smooth a bead.
Hope that helps, or maybe I'm too late & you've already done this work. Sorry if that is the case.
Happy new year!
