The acetate would very likely be soluble in everclear (ethanol) just like it is in IPA, but not soluble in d-limonene.
The d-limonene left should be very minimal anyway since separating the vinegar phase from the d-limonene would pretty much get rid of the immiscible d-limonene. If you are concerned there is still d-limonene in there (smelling or seeing a significant amount) it would likely be because your separation of those phases was too liberal and you allowed d-limonene to come along to salvage product. Probably not a good idea, I would make sure to get rid of the d-limonene, that will cost you a little yield but it's no good trying to purify it away later in some simple way.
So: I absolutely don't think ethanol works well because it is miscible with vinegar AND d-limonene, dissolves your mesc acetate (does not affect it per se)... so it achieves nothing.
If you instead dissolve your product in water (not sure it is necessary to use distilled water - normally I use it on principle, but salts dissolved in tap water shouldn't hurt to separate - sometimes salts - a la brine - can even clear up extraction phases because they facilitate dissolution of some compounds rather than them being only half-dissolved and sludgy.), the limonene becomes separate from your watery solution because it does not mix with the water. Basically you revert to your earlier step before separating the vinegar from the d-limonene giving you a do-over. Only without having to add even more vinegar which you would then have to get rid of again. This time just make sure drops of limonene are gone and it should be ok.
Having to get rid of the vinegar (acetic acid) seems pretty annoying to me, though I have no experience with food dehydrators like in the tek - it might very well be fine to just help up evaporating the decently volatile acetic acid. Don't know if you can just as well heat your solution up a bit with a fan wafting a very slight draft over it.. don't know how you managed with the vinegar in the first place.
Apparently the big plus of this tek is it involving benign compounds, but a drawback is that it may be extra annoying to clean up the last impurities.
What is the current condition / appearance of your product?
