Apply a small amount of the oil-containing cleaner onto the tree sap, making certain the sap is completely covered.
Allow cleaner to sit for 15 to 20 minutes. This gives the oil time to soften the sap.
Scrub the affected area gently with the brush, taking care not to damage the furniture finish.
Repeat the entire process if sap remains after the initial cleaning. Repeat until all the sap is removed.
Test a small portion of carpet with rubbing alcohol to ensure it won't discolor the fibers before attempting to clean the sap. Pour a small amount of alcohol on a clean cloth and gently wipe an inconspicuous area of carpeting. If carpet dye does not transfer to the cloth, you can proceed.
Place several ice cubes into a plastic sandwich bag. Hold the bag of ice against the tree sap to harden it, then peel off as much of the hardened sap as you can.
Wet a cleaning cloth with the alcohol and gently wipe the surface of the affected area of carpet, gliding over the fibers rather than pushing down.
Blot the alcohol from the carpet with a clean paper towel until dry.
Repeat steps 3 and 4, always using a clean cloth and fresh paper towels, until the surface of the carpet no longer feels hard and sticky to the touch.
Clean deeper into the carpet by wetting the cloth with alcohol and gently pressing it into the carpet with the tips of your fingers.
Blot the area dry using clean paper towels.
Repeat steps 6 and 7 until the carpet feels soft and you can no longer smell tree sap.
