First few minutes
Just happened? Do this first
- Move the car into shade and let it cool.
- Rinse off the loose dirt before the paint is touched.
- Pre-soak the spot, then wash with mild car soap and cool water.
- Spray a clear-coat-safe remover on any tar, bugs or sap.
Bird droppings can damage car paint in just a few hours, and tar, sap and insect splatter do their own damage if they're left to sit. Water is safe on paint, but heat and abrasives are not, so keep every step light. If etching has already set in, there's no home method for it, and the fix is a proper repair.
Use a bug and tar remover on tar or sap, applied to a cool panel. A clay bar can lift leftover bonded grit after the wash, but glide it lightly and keep the surface wet. Matte paint doesn't handle the same way as glossy paint, so test any product on a low corner first.

7 steps
Step by step
Step 1 of 7
Move the car into shade
Park the car in shade and let the body cool before you start. Insects, tar, tree sap and bird droppings can damage the finish if they stay on, so start soon.
Careful. Never wash a car that is hot to the touch or sitting in strong direct sunlight.
Step 2 of 7
Rinse off the loose dirt
Spray the whole car with water until the loose dirt is gone and the surface is wet. Only then should anything touch the paint.
Careful. Don't wipe dust or dirt off with a dry cloth, because it scratches the finish.
Step 3 of 7
Pre-soak the spot
Coat the spot with car soap, or with a waterless wash or instant detailer if you are not ready for a full wash. Let it sit so the deposit softens before you wash the rest of the car.
Careful. Don't let the soap dry on the finish.
Step 4 of 7
Wash with mild car soap
Wash the car with lukewarm or cold water and a mild soap made for painted surfaces. Rinse your wash mitt often so you are not dragging the deposit back across the paint.
Tip. Work from the top of the car down, so the dirtiest panels come last.
Careful. Never use hot water, strong soap or chemical detergents on the paint.
Step 5 of 7
Use a clear-coat-safe remover
If tar, bugs or sap are still there, spray on a bug-and-tar remover labeled safe for clear coat. Let it sit to soften the deposit, then wash or rinse it off.
Careful. Don't scrape tar or bugs off with a scraper or other sharp object.
Step 6 of 7
Clay the paint if it is rough
If the washed paint still feels rough or spotted, rub a clay bar over the cool, clean paint. Work one section at a time with a detail spray so the area stays slick.
Careful. Never clay a dry surface; keep it lubricated at all times.
Step 7 of 7
Re-wax the treated area
Re-wax the spot you treated, because spot removers usually strip wax. Choose a wax that does not contain abrasives.

Best stain removers for car paint & exterior
Look for a car soap made for painted surfaces, a bug-and-tar remover labeled safe for clear coat, and a wax that does not contain abrasives.
How we picked these: each product is made for this type of stain, its maker doesn't warn against using it on car paint & exterior, and its directions fit the steps above.
Finished the steps? How does it look?
Nice work. Let it dry completely and check it again in good light. Here is what done looks like:

How to tell it's working
When the washed paint feels smooth and shows no spots, the spot is clean. If it still feels rough or spotted, the clay bar step is the one to do next.
What changes for yours
Adjust for your car paint & exterior
Matte paint
Matte paint needs the gentlest route of all. Skip polish, abrasives, wax-finish cleaners, rotating-brush car washes and steam cleaners, even on a tough spot.
Stick to the pre-soak and a hand wash with mild soap and cool water. Use the remover only where tar, bugs or sap actually sit on the paint, and work one section at a time so the finish stays even.
Stripes and graphics
Stripes and graphics follow the same steps as the rest of the car, from the rinse through the wash. If a deposit sits on one, treat it the same way with the pre-soak and the remover.
Once the spot is gone, look over the edges of the graphic before you move on. If an edge looks lifted, stop and have it checked rather than pulling at it.
Headlight and taillight lenses
Headlight and taillight lenses get the same rinse and pre-soak as the paint around them. The mild car soap wash works on them as well.
Check the lens for any deposit the wash missed before you re-wax the panels next to it. Keep the wax itself on the painted panels.
Bird droppings and insect splatter
Bird droppings can damage paint in just a few hours, so this is the spot to deal with first. Give it the pre-soak straight away, then wash it with the same mild soap and water as the rest of the car.
Insect splatter follows the same route, since bugs can dry hard on the finish. Use the clear-coat-safe remover on any that are left after the wash, and let it soften before you rinse.
Old, dried or set-in stains
If a deposit has been on the paint for a while, the steps above may only soften it rather than lift it. Give the remover a second round, and let it sit longer before you rinse.
Once a spot has dried and marked the clear coat, a home wash usually can't reverse the damage. Don't reach for a stronger solvent, a scraper or a polish to dig it out, because that is how paint gets hurt.
If the mark is still there after the wash, clay and re-wax, the paint itself is damaged rather than dirty. At that point the realistic fix is a professional repair, not more scrubbing.
Vinegar, baking soda, peroxide and more
Do home remedies work on car paint & exterior?
Plenty of household remedies get passed around for stains, but car paint is a different case. Car soap and a remover made for clear coat do the job, and most kitchen options don't suit this surface.

What makes it worse
Mistakes to avoid
Don't use dish soap or laundry detergent
Kitchen detergents are made to remove grease and wax, so they take the protection off the paint along with the dirt. Stick to a mild soap made for painted surfaces, even when the car looks grimy.
Don't reach for benzene or gasoline
Organic cleaners like these are not meant for painted surfaces, even on a stubborn spot. The remover labeled safe for clear coat handles tar, bugs and sap without that risk.
Don't aim a high-pressure sprayer at stripes
A hard blast of water can lift the edges of stripes and graphics. Rinse those areas with a gentle flow instead.
Don't wax headlight or taillight lenses
Wax belongs on the painted panels, not on the lenses. Keep the lenses clean with the same wash you use on the rest of the car.
When to call a professional
Deep scratches and chips should be repaired promptly and covered with touch-up paint to reduce corrosion. If a body shop does the work, make sure it applies anti-corrosion materials to any repaired parts.
Questions
Can I use dish soap to wash car paint?
No. Dish soap is a degreaser, and it strips the wax and protection off paint. Wash with a mild soap made for painted surfaces and lukewarm or cold water instead.
Is hot water okay for removing bird droppings?
No. Use lukewarm or cold water, and never wash a car that is hot to the touch. Pre-soak the spot first so it softens before the wash.
How fast do bird droppings damage car paint?
They can damage paint in just a few hours, so the sooner you remove them, the better. Treat the spot the same way as the rest of the car, starting with the pre-soak.
Can I scrape tar or bugs off my car?
No. A scraper or sharp object can mark the paint, so use a bug-and-tar remover labeled safe for clear coat instead. Spray it on and wait for it to soften the deposit before you rinse.
Can I clay a car that is still dry?
No. Clay only cool, clean paint that stays lubricated the whole time, one section at a time. A dry surface can scratch.
What should I avoid on matte paint?
Polish, abrasives, wax-finish cleaners, rotating-brush car washes and steam cleaners are all off the list. Pre-soak the spot and hand wash it instead, keeping every pass light.
