Moisten a rag with hot water. Wring it out well. Scrub the sap vigorously. Move to clean surfaces as you dirty the rag. Keep scrubbing until no more sap is transferred to the rag. If the sap remains, wipe the wood dry and move on to step two.
Mix a solution of 1 tablespoon glycerin soap and 1 quart hot water.
Moisten a rag with the glycerin solution. Wring it out well. Scrub the sap vigorously. Move to clean surfaces as you dirty the rag. Keep scrubbing until no more sap is transferred to the rag. If the sap remains, wipe the wood dry and move on to Step 4.
Put on a pair of rubber gloves.
Moisten a rag with mineral spirits. Wring it out well. Scrub the sap vigorously. Work carefully. Wrap the rag around one finger and concentrate your scrubbing on the sap. Try not to scrub the surrounding floor any more than you can help. For more precise application, use a cotton swab. Keep scrubbing until no more sap is transferred. If the sap remains, clean the mineral spirits residue up with soapy water. Let the wood dry.
Tape off the wood surrounding the sap stains.
Scrape the hardened sap away with a razor blade, sliver by sliver until there is only a thin layer left on the floor. Hold the edge of the razor blade as close to parallel to the floor as possible as you scrape to avoid scraping or gouging the surrounding floor.
Remove the tape.
Repeat Steps 1 through 5 until the residual sap is gone.
