I have several spots where the natural oil in the ipe has been squeezed to the surface by the pressure of the clamps during glue up. This creates a darker circular mark where the clamp pad was. I have seen this happen before when I clamped the wood while routing the tenons and it eventually faded away but it took a while. I am leery of sanding and applying my oil sealer with these spots still visible. Any suggestions? Have u seen this happen before?

Would alcohol, mineral spirits or acetone remove the oils well enough to get rid of the oily patch?

Clean it with solvent as Mark says. If the dark spots still remain it means the fibers have been compacted, in which case raising the grain with hot water might even it out.

With oily woods such as ipe, I clean the oil from all surfaces with acetone or alcohol just before finishing. Mineral spirits or paint thinner also works but I don’t like waiting for it to dry. With especially oily wood that’s often enough time for the oils to wick back to the surface, which kind of defeats the purpose.
