We have finished gluing up a nice project, sanded the project and think that we have all the glue squeeze out removed. We put on a nice coat of stain and find out that we DID NOT get all the glue off of the project and it looks like crap!

I think that this has happened to all of us at some point.

My question is this: How do you check your work for glue residue prior to staining?

I can usually see it when I wipe down with mineral spirits before finishing.

Same as Sergio – little mineral spirits – - – laquer thinner evaporates too fast

I also wipe the project down with mineral spirits. Remember to use a raking light (bright light shining across the project at an angle) at the same time to see defects when you do this.

One thing you can do is mask your glue area and stain first. Or, you just don’t have the problem with hide glue.

Mineral spirits take sooo long to dry, use ACETONE. It also removes glue.
It also is great for checking leftover glues.

CR is right… let it dry and then clean it off with a good sharp chisel and or cabinet scraper. But I would like to add an interesting comment. I use a popular market glue and reading the instructions on the back, it tells me to use a wet or damp rag to wipe off the excess glue before it dries. Do not follow their instructions… DO NOT WIPE EXCESS GLUE WITH A DAM RAG! What that does is very bad. This dilutes the glue and allows it to penetrate deeper into the wood. There is nothing wrong using mineral spirits, but I prefer to use water. Whatever you use, be sure to put a light on it and look at with using an angle so you can detect the glue in the shine. My preference for water is that it shows me all the blemishes like mineral spirit, but it also pops out my dents. Don’t drown your work, simply dampen it. Done correctly, you can apply your finish within 20 minutes.

You can use a black light with some glues. I’ve never tried it.

With furniture I pre-finish.

I’m also very neat with glue. Let it get soft-hard then wick it off
with a pointed stick or a drinking straw cut at a steep angle. The
excess you can scrape off with a razor blade. I do this on guitar
bracing.

Don’t use too much. Don’t try to clean it up with water. Bad.

A pair of angle chisels is very useful for glue squeeze out. Angle
dog-leg chisels are even better.

Dry assemble, tape along all joints, cut tape between pieces and glue up. Peel off tape and all squeeze out. I do this with all glue joints even though I don’t use stains, just clear finishes.

I second the use of acetone. When I’m having problems getting to the glue with a chisel, I’ll put a little acetone a qtip and rub it over the glue. That usually does the trick. Thought I’ve always been a little concerned about getting acetone into the joint itself and weakening it.

You do not want to be soaking acetone on the wood or else it will remove the joint glue. Wipe off Acetone immediately after you remove the glue.
