Just finishing some sandblasted signs and was wondering what you would do to do a final clean of the sign. My concern is the sandblasted portion of the sign which has been stained and clear coated. There has been sansding of the remainder of the sign and dust has settled in the grooves of the blasted portion. Should I blast it with a low pressure water sprayer? What would you do?
Thanks for your time.

Corey,
I'd take a soft brush and a hose to it. Hopefully, you waited long enough for the clear coat to cure before taking the sander to it.
Don't panic!
Cher.

Sanding Dust>>> Your compressor air nozzel w/ about #50 PSI. If the project is gold leafed, be careful not to blow directally on it.
Enamel smudges>>> Your gonna think this is funny, but, nose oil works great. Take your index finger, and rub the side of your nose.
For the tough stuff, you'll have to pull out the brushes, and fix it.
"I'm still looking for something that takes off an old stibilo line. The blue ones stain the "sub" if you leave it on for, say, a week."
I'm with Richard on this one. I keep a couple of cheag china bristle brushes in the shop and using these with shop air it seems to work fine. As Richard says, if you have gilding, be careful. Fifty lbs. of presure is plenty. And as Cheryl says, I hope your clear was plenty dry before you got sanding dust in it. As a side note, I find that often we rush jobs because the customer needs them or we need the money. Most times this results in FU's that in the long run cost time and money. One of the biggest problems I have in our shop is people doing second coats or other things before the first coat is good and dry. Just an observation!

Those stains from certain colors of marking pencils usually come out with a little Comet on a clean, damp rag. Watch out for freshly painted lettering... this cleanser is slightly abrasive and could pick up some of the color and rub it into the background. Just do it LIGHTLY, then rinse with water. 'Works for me!
