Hello,
I did a lacquer finish on my project. I sanded it with wet/dry paper using mineral spirits, starting with 600 grit, then 1000 and lastly 1200 grit. The sanding has left residue on the surface that I can not seem to get ride of. I’ve wiped it down quite a few times with mineral spirits, i’ve tried using a little soap and water and i’ve even tried using a all purpose cleaner, but it’s still there.
I would like to get some suggestions on how to get rid of the residue.
Thanks,
dp

Well, the only time I sand lacquer is for the first one or two thinned coats. Then I just dry sand it with 400 grit paper and use a blow gun and a dry rag to remove the dust. The last coats are not sanded. I let it cure for several days then buff it out with a lambs wool bonnet on a buffer running at slow speed. Or, I use 0000 steel wool by hand to buff it out then do the final buffing by hand or buffer.
I have never wet sanded lacquer and I don't think one should. But having never done it, I guess I can't really say though! Wet sanding with water might cause the lacquer to turn milky colored.
I used to use lacquer sealer under lacquer, but lately I been using dewaxed shellac for the sealer.
Probably your best bet now would be to apply another coat.

I can't imagine a residue left after all you've done! Are you sure it's just not the lustre showing? It should not be glossy, should be a shiney satin.
Need some ???'s answered first. Type and or brand of Laq? How much did you put on, how many coats? Did you use a sealer? How do you want your end product to look, rubbed satin or glossy?
Maybe this will help you get the finish you want.
I used Deft spray lacquer, comes in the spray cans. I put 7 coats on and let it cure for 2 weeks. I was following the procedure to get a nice rubbed look, as laid out in the book "Understanding Wood Finishing". I did not use a sealer. Perhaps it wasn't sanded enough prior to staining and finishing. The project is a fireplace mantle with lots of routered edging. The residue isn't everywhere, just in about a 1/4 of it. The top of the mantle looks fine, nice and flat and smooth, but the middle section with a heavy crown molding going the length of the mantle is just terrible.thanks,

Are you looking for a gloss finish or a satin finish? For satin, just apply a coat of paste wax using a white scotchbrite pad. Buff and enjoy.
If you want more of a gloss, you will have to do more work. After the 1200 W&D, use an automotive polishing compound applied with a power buffer or a buffing pad on your ROS. Be sure to use polishing compound, not a rubbing compound. Periodically wipe off the haze to see where you are. Be careful about burning through the finish particularly along the edges.Howie.........
I think Howard has the best advice, just wax it with a scotchbrite white or Gray pad. The gray will make it a bit more satin. Use a furniture wax or floor type wax. I would use a dark brown if it suits your color.Furniture...the Art of a FurnitureMaker
dperfe,
I've had this problem with open grained woods when I haven't filled the pores. Leveling the lacquer by sanding will sometimes embed the slurry into the pores, or the corner between a molding and what it's nailed to. Especially if there isn't a lot of finish there to begin with. Best treatment I've found is another coat of lacquer, or a quick wipe with lacquer thinner. It helps to use a lubricant like petroleum jelly or a proprietary product (wol-wax by star chemical comes to mind) when steel wooling lacquer, to prevent this as well.

Try an automotive wax spray, like eagle one"wet look". I guarantee it.
