I think tack cloths are most valuable between coats of VARNISH because every nib of dust seems to show up. If the cloth is laid out flat and lightly skimmed over the surface, I don't think any residue is transferred. I get as much dust off by other methods first, then wait a few hours for any airborne dust to settle, then tack cloth quickly and lightly before each coat of varnish. Arms should be bare and just washed and dried. Shirt is optional. Pants too I guess.

: Hello forum members,
: I have read everything I can find on epoxy and varnish application
: after sanding clean-up before application of second - third etc
: coats.
: Some say do not use tack cloth prior to the applications because it
: leaves a chemical residue and causes the appearance to appear
: foggy.
: Some recommend using the tack cloth to remove all the fine sanding
: dust from the scratches caused by sanding with 220 grit/320grit.

: I have been using the blue shop towels dry to rub off all sanding
: residue after vacuuming the surface, which does an excellent
: clean-up job for the next coat.
: I would like the forum members opinion and input on this procedure.
: I am wondering if I am using the best technique of clean-up or
: is
: the tack cloth the way to go.

: Thank you. Douglas
