Sweep the sap-stained hardwood to clear away loose dirt particles, which can scratch the floor's finish during sap removal.
Prepare to use a solvent on the sap stain. Begin by opening nearby windows and switching on fans to provide abundant air circulation. Slip on a pair of chemical-resistant gloves, as well.
Moisten a cotton cloth with mineral spirits. Rub the sap with the mineral spirits, dissolving as much gummy residue as possible.
Examine the hardwood for stubborn sap. If any dried-on sap or stubborn sap residue remain, dampen a plastic sponge pad with turpentine.
Scrub the remaining sap off the hardwood using the turpentine-dampened sponge pad.
Moisten another cloth with water. Wring the cloth well, and then wipe the hardwood to rinse away the mineral spirits and turpentine.
Buff the moist hardwood with a dry towel.
