You will read that WestSystems wants teak strips solvent washed not more than 30 minutes befor epoxy gluing teak to a deck.
(By the by System Three totally disagrees with WestSystem's use of epoxy to glue teak strips to a deck and making an epoxy 'caulk' line that would normally have two-part polysulfide.)
Acetone is not actually a benign solvent. But it has been traditionally used as a solvent and medium cleaner for polyester and epoxy work on boats.....without directly killing workers. (lesser evil than MEK for instance.) So dewax with instant drying ACETONE, not naptha or lacquer thinner as sometimes advised.
Since we don't know what epoxy you are using, it may be best to wipe the top teak/holly ply surface with acetone just befor applying epoxy. BUT
FIRST
I would wet wipe a test scrap to get a feel for it, see if anything happens to the wood and its glue lines.
If it seems OK, only then would I wipe the plywood surface with a DAMP acetone rag, just in case some shenanagans were used to put the holly strips into the teak. Keep solvent out of the wood seams. Never know.
