We attended a recent car show with the Moffstang and Coca Cola transporter and thought we had done well when we scored a great shaded area under a tree, it was a hot day and the shade was well received, but a few hours later we realised something else, the car and truck were totally covered in tree sap.. Oh dear god no! So this quick article on how to remove sap quickly and safely has come from our misfortune.
The nice park that we paid for later!
Firstly, it is well worth pointing out that tree sap is not actually from the tree’s dropping sap, it is from a number of different varities of insects, that are feasting on the tree. They call the dropping residue the nice name of honeydew, which is just another name for bug poo! These insects really become active and swarm in the warmer months, much to our annoyance on that lovely warm spring day!
Prevention is always best, so the ways to stop this happening is to not park under tree’s (obviously), if the park is at your home, look at investing in a carport, or getting rid of the offending tree (not always practical). You can look into getting rid of the insects, with a pesticide (usually not good for the tree’s) or with other bugs that eat the tree eating bugs, with ladybird bugs being a popular one with many female gardeners.

Thankfully if you get to remove the residue quickly, it is not that difficult. The longer you leave any of the sap, the harder it can be to get off the paint, and if left long enough it will become black and sooty due to mould. So with that in mid we have our list of ways to remove these sap residues that are a few days old, to neglected cars with it left on for a longer period. It is worth noting that there are some types of tree sap that give the bugs an acidic excrement (that would be fun for the bugs no doubt), so it is quite important to remove it ASAP, otherwise it will etch into the paint surface, leaving small circular "water" marks after you have cleaned all the residue off. If you do unfortunately get these marks after following our steps below, I would suggest you call your local professional detailer to remove these marks with a good machine polish.

STEP # 1: WARM WASHING
For one to two days after tree sap falling- Wash with warm water and an Auto Body Gel car wash concentrate. Prepare a warm wash solution, in our 12 litre BOB Bucket, with two cap-full’s of Auto Body Gel and warm water (not hot enough that you can still put your hand in the bucket). Hose the car down, then begin washing with our Love Glove or Muffy sponge. Likewise, you can also leave the car out in the sun for 10 mins before you wash (Yes we know this breaks one of our cardinal sins of washing cars), as the heat from the sun will soften the residue and make it easier to remove. Chamois the paint dry and inspect the car to see if it is all gone.
Body Detail is quick, clean and easy, if you get to it early.
STEP # 2: BODY DETAIL
If you have a show car and do not like using water, try our Body Detail spray, this is what we used on the Moffstang and it worked beautifully. Spray on quite thick, let it sit for a 30 second interval then wipe clean with the microfibre Buffing Cloth, turning over regularly so you’re not putting the residue back on the car. It can pay to have a few clean microfibre cloths on hand, to keep swapping them over to fresh ones in the cases where the residue is quite thick.

STEP # 3: BUG AND TAR
If you have let it go a little bit longer than a few days and the above process did not work, our next level of cleaning is to use the Bug and Tar spray. This high end cleaner will quickly work at breaking down the residue and making it easy to remove. Wash or use the Body Detail as above, then park the car in the sun to warm up the panels, then put back in the shade and spray the Bug and Tar on the areas affected, leaving it sit for a minute or two. Then wipe off in a gentle circular motion with our folded Wheel and Lower Body microfibre cloth, then wash it down clean with the hose. Once done, inspect the car to make sure you have got it all off, if there are still a few stubborn areas, spray the Bug and tar into the cloth and rub it directly into the area; this should remove nearly all but the hardest residue. If it does not, we have our final solution for the most dramatically covered and neglected cars out there.
Bug and Tar is safe with all the painted finishes, but you will have to re-wax the car after.
STEP # 4: CLAY BAR
If the tree sap has been on the car for a loooong time and dried hard to the paint, we have one final non damaging solution; Clay Bar. Now this is only for hard dried sap on the car, as is it is soft the above procedures will be far more effective. Basically use it as per the instructions with either the Auto Body Gel or Body Detail spray as the lubricant, read our in depth article on using it by clicking here. We do not recommend keeping the clay after using it to remove sap, so throw it away.
Clay barring the car is only for harder, older sap residue.
Buff it down after finishing to get that beautiful smooth surface back once again.
After doing these procedures, you should have no more sap, so be sure to then use the Auto Body Cleanser and then a coat of the Auto Body Wax, as the layer of wax will offer protection and make cleaning off the tree sap residue that much easier next time you're silly enough to park under a tree!
All the microfibre cloths can be washed and reused as well, read about doing this here.
