1 – Goo Gone can also be of help to remove sap from wood
Ultimately, Turpentine works great for cleaning sap from any wood surface. In my humble opinion, Turpentine in one of the best options out there.

Are you okay with the idea that you may have to apply an additional layer of Bin sealer every few years to prevent the remaining sap from oozing out? If that doesn’t sound acceptable to you, then it might be better to simply replace the affected wood.

For a start, you need to clean all the sap which is gradually crystallizing on the top of the affected wood. Turpentine works perfect for this purpose and it will not damage the quality of the wood. Use a coarse plastic sponge to scrape the oozed resinous compounds and go over the surface of the wood with a clean towel. As mentioned above, Goo Gone can work fine, too.

Many people will automatically opt for sandpaper in order to clean the sap. However, mind that it will gum up very quickly. Thus, it’s best to use sandpaper for polishing the surface of the wood well once you have already removed the sap with Turpentine or Goo Gone.
Step 2 – Treat the affected areas by sealing them properly

You can stop the sap bleeding from wood by either staining the affected surface after cleaning the ooze or by bin sealing the knots and re-painting. Typically, a bin sealer is used for cases when you are dealing with very stubborn sap. For example, if you live in a region where the weather is hot and dry, this will encourage sap to keep coming out of wood.
Thus, bin sealing the knots and re-painting is a better option for you. On the other hand, staining can work very well, too but it’s the wiser alternative for those of you who live in more humid and/or cold climate zones.
