How to Remove Tree Sap From Car

Remove Tree Sap From Car

Life at the cabin would not be the same without the majestic 100+ year-old white pines on our property. As awesome as these soaring, scented, swaying beauties are, they do present one big problem – that is; how to remove tree sap from cars parked under them?

After more than a year under the pines, our go-to cabin car was a mess. Knowing it was going to be a total pain in the butt to get the sap off, I did what every serious car enthusiast would do – I ran it through the service station wash a half a dozen times and hoped for the best.

By the time I finally realized the sap wasn’t coming off, most of it was very hard and really difficult get off. I did a bit of reading and after trying a few things, I found that a two step process worked best to remove the tree sap.

The first step was to use denatured alcohol and the second was to finish with automotive detailing clay. The alcohol removed the bulk of the sap and the detailing clay cleaned up the inevitable haze that the alcohol sap mixture left behind.

I found that the two step approach was much better than either step by itself. If I used just the solvent (denatured alcohol), the diluted, liquefied sap and alcohol mixture left a nasty, sticky haze that was hard to remove.

If I used just the detailing clay, it took too long to remove large, hard dried deposits, and each deposit used too much of the clay. The answer; use both.

Automotive Detailing Clay, Say What???

If, like me, you had never before heard of Detailing Clay here is a quick description of what it is: Automotive detailing clay is a putty-like compound embedded with very fine abrasives used to clean car finishes. Detailing clay or clay bars are used in the automotive industry to remove fine contaminant from car finishes.

Detailing clay does an excellent job removing contaminants from car finishes and for this project was the perfect solution to remove the trace residue of tree sap left on the car finish after using alcohol.

So, here it is, the CabinDIY 2-step tree sap car removal formula:
  1. Denatured Alcohol – dissolves and removes most of the sap
  2. Automotive Detailing Clay – removes residual sap (haze) 
The entire process start to finish:
  1. Wash and rinse car
  2. Use a denature alcohol (ethanol) soaked rag to liquefy and remove tree sap deposits
  3. Re-wash car to remove the alcohol and sap solution
  4. Use automotive detailing clay (clay bar) to remove trace amounts of tree sap (haze)
  5. Apply car wax or sealant

How to Remove Tree Sap From Car – Step by Step

  1. Wash car

    Using car wash detergent or similar, hand wash car to remove dirt and contaminants. Use two buckets, one for wash and one for rinse, to keep wash soap water cleaner. Thoroughly rinse car after washing.

  2. Use denatured alcohol to remove tree sap deposits

    Using denatured alcohol and a microfiber cloth, rub tree sap deposits to remove. Turn cloth frequently and re-soak with alcohol to reduce residual sap haze left on car finish. Continue removing deposits until all deposits are removed including those on the windshield and glass.

  3. Re-wash car over areas where alcohol was used

    Using fresh soap and water, re-wash the car over the areas where the denatured alcohol was used to remove sap.

  4. Use detailing clay bar to remove residual tree sap haze

    Open clay bar packaging and form detailing clay into a flat pad by kneading bar. Apply soapy water or clay bar lubricating solution prior to using clay on car finish. Once wet, rub clay pad back and forth across car finish using light pressure until surface feels smooth and no longer “catches” on paint surface. I found it helpful to lightly spray water on the car as I used the clay bar. Rinse with clean water after using the clay bar.

    Use clay bar on windshield, chrome and plastic trim as well – it works well on remove tree sap haze on most surfaces on the car.

    When using detailing clay, understand that dirt and other contaminants stick to the clay. Refresh the clay surface by folding it over and kneading during use to keep clay surface clean. Also, use clay on cleaners surfaces first to help prevent moving dirt and other abrasives to car surfaces. If you use a clay bar on wheels or similar surfaces, you should probably have a dedicated clay bar for those relatively “dirty” surfaces. If the clay falls onto the ground, remove and contaminants or discard clay to prevent damaging paint surfaces.

  5. Apply car sealant or wax

    Restore car finish by re-applying wax or sealant. Follow the directions for the product you are using. I used a silicone based sealant, which can be whipped on, then buffed off once it dries to a slight haze. I used a microfiber cloth to apply and remove the sealant.

    Interesting. Why denatured alcohol (ethanol)? I’ve been using rubbing alcohol. First I gently pop the sap off with my finger nails than use the alcohol to get up the last underlayer. I do all this right before the car wash!

    Any advantage to one kind of alcohol over another? I’ll definitely look for the detailing clay.

      Hey Jason,

      Both Isopropyl alcohol and denatured alcohol (ethyl alcohol) will work and are generally accepted as safe (especially if diluted with water) on car finishes (they do removal waxes and sealant though).

      Many suggest thinning isopropyl alcohol with water prior to using. Both can be mixed with water before use, reducing their solvent characteristic and potentially making them safer to use on finishes. Bottom line is both are probably safe with modern car finishes, and even safer if diluted with water.
