I'm using Cardinal's pore filler on my current project. I'm concerned about cleaning before applying their sealer. What solvent is safe to use?

I wipe down with DA prior to applying any finish materials.

Cardinal's product info sheet on their 4760-Series Alkyd Pore Filler says:

3. Clean all grease, oil, and contaminants with acetone or naphtha like solvent
4. Seal the wood and allow the specified amount to dry.

Also, ask Cardinal for their Musical Instrument Coatings Nitro Cellulose Finishing Process instructions.

To be clear, the filler has already been applied. Concerns about softening/removing the filler while cleaning printed the question.

Info i have only says:
"Ensure clean surface"
I would think that a light careful wipe down of naptha, DA, mineral spirits, or acetone would do the job just fine after the filler has dried sufficiently.
You can always do a test piece.

I sand w/320 grit, wipe with dry cloth for water base filler, spray with air hose , and apply 1# coat of shellac for sealer, before spraying or varnishing.

You need to be careful wiping down between coats. Fresh nitro can be reactivated with something as mild as DA or naptha. After I start applying materials its tack cloth only for cleaning.

Brian .Is your tack cloth have a solvent/finish in it, or just a plain cotton rag? The reason I ask , is I had a tack cloth once , and it had something sticky in it that picked up dust, but wasn/t sure what ingredient it was ??

The tack cloths are sticky cheese cloth type things. They are safe with nitro and other solvent based systems I have used but I extremely caution there use with any type of natural finish like real varnishes, drying oils and shellacs as I have had problems with some of those combinations in the past.

I googled ,and found a light damping with thinned tung oil ona coton rag,left in a tight glass jar . Tried it sunday, for cleaning between thinned cabinet varnish.

I wouldn't use that when using lacquer but it should work fine for vanishes and other natural finishes. Careful of the rags you choose....lint and small fuzzies can be left behind and you won't see them until you are putting on the next coat.
