Repairing Car Paint With Bird Poop Damage

Repairing Car Paint With Bird Poop Damage

Now, the acid from bird droppings is fast-acting. But you have a whole day to clean it off before it causes serious damage.

Paint damage occurs if you neglect your car. So, I guess you didn’t clean off the poop fast enough. You may have a minor stain or a big one, depending on how long the poop stayed there. The cleaning process depends on whether you have a minor stain or a big one.

Treating Minor Stains

  1. Remove caked-on bird droppings.
    I guess most of you have already removed the droppings, that’s how you found out about the stain. If you haven’t, get WD-40, spray it on the poop. Let it sit for a minute or two, wipe away with a soft cloth. You can also use a damp cloth dipped in warm water for wiping.
  2. Wash your car.
    Give your car a regular wash. Car dedicated wash soaps are recommended.
  3. Get a compound. 
    You need a compound that removes scratches, swirls, and acid stains. There are many car cleaning products you can choose from. I recommend Meguiar’s Ultra-Cut Compound. It acts fast, and it can be applied by hand. Perfect for treating topical stains by hand.
  4. Apply compound. 
    You don’t need a buffer for topical stains. You can apply the compound by hand with an applicator pad. Follow the instructions on the product you bought.

This should remove any topical stain and restore that nice gloss finish.

Treating Bird Poop Etching

This is the worst-case scenario. Tropical stains damage only the paint surface, so it’s not that dangerous. Etching occurs when multiple paint layers are damaged. Major stains like these require tools to be fixed. Not only that, expertise too.

You will need a dual-action polisher or a buffer. You may be able to level surface with dry sand paper, but you will need a buffer for the polishing. So, if you don’t have a buffer you won’t be able to do this. Consider getting one or contact a professional detailer. Check out the 10 Best Electric Buffer For Car Waxing & Buying Guide.

  1. Remove any caked-on bird excrement.
    Just like before, make sure all bird droppings on your car are gone. Use WD-40 to remove old bird poop. Use poop car wipes for fresh ones.
  2. Prep your car. 
    Now is the time to wash your car like you never did before. I mean it should be squeaky clean. Use the two-bucket method. Use a high-quality car wash shampoo. Get rid of any stuck particles. Dry the car with a clean microfiber cloth. Make sure you are using a dry cloth.
  3. Level the paint.
    This is a complicated step. Right now, the stains and the rest of the paint are not on the same level. So, you need to bring the rest of the paint on the same level as the stain. To do this, it’s best to use an electric buffer. Attach a microfiber cutting pad to the buffer, and add cutting compound. Slowly work your way through the surrounding paint. If the stain is on the hood, work on the entire hood. Then, use a softer buffing pad and a fine rubbing compound. Finish with the finest grit.
  4. Polishing the paint. 
    The step you did before will leave you with a shineless finish. You need to restore the paint to its original glory. Again, you need a buffer here. Attach a soft buffer pad and a fine polishing compound. Work your way through the paint slowly, following patterns. Change pads to avoid swirls. Repeat this until you get a fine glossy finish.
  5. Add a layer of protection to the paint. 
    You can go with anything here, waxing, Clear Bra, or ceramic coating. Whatever you choose, it will work just as fine.

There you go, that’s how you treat paint etching. Remember though, this is something that inexperienced people shouldn’t do. If you don’t know what you are doing, just don’t do it. You will cause even more damage.

To visualize things, I will leave a video on paint detailing. However, if you still don’t feel confident, just take your car to a professional.

Professional Car Detailing

For beginners, I highly recommend just taking your car to a professional detailer. Here’s the thing, you probably don’t have the equipment needed for polishing and dealing.

If you are going to be buying a buffer, polishing pads, etc, just use that money to pay a professional. It may be more expensive but it’s worth it.

Topical stains you can fix yourself. Don’t take your car to a professional for a topical stain. You don’t need equipment for that. However, for bird poop etching, just go to a detailing place.

Some people know what they are doing. I don’t think those people need my guide though. I am guessing most of you are beginners that don’t even have the equipment.  If you are willing to buy the equipment, a full detailing kit is best.

In case you have the needed equipment but don’t know anything about detailing, do your research. Follow this guide and more. Plan out what you need to do. Consider whether it’s worth the risk.

All in all, beginners should not do car detailing. Just go to a professional and let them handle it. They will fix any paint damage that your car has. More so, they use techniques that you can’t really find on YouTube.

How Does Bird Poop Damage Car Paint

How Does Bird Poop Damage Car Paint

It’s already clear that bird droppings can cause serious damage to the paint. But how does that happen? Bird excrement contains acid that comes from the stomach. It’s called uric acid.

This helps birds break down hard to process foods. Have you ever wondered how a bird that is so small can eat so many different things? Well, this is why.

The uric acid has very high levels of pH. So, it’s very corrosive. When it comes in contact with the paint job, it starts to corrode the surface layers. This is how topical stains occur.

However, this is not that dangerous. Clear Bra and ceramic coating are pretty good at protecting the paint from bird poop.

But if the poop stays on the paint for a while, more serious damage occurs. Combined with UV rays, the poop can eat way the coating too. Hence, it causes etching. That’s why you need to clean bird poop as soon as possible.

How To Clean Bird Poop On Car Paint

Since it’s really important to be quick when cleaning bird poop, you should know some of the most effective ways to do that. Here are some tips. The removal process depends on how dry the poop is.

Cleaning Fresh Poop

  • Use a soft cloth dipped in a car cleaner.
    The bird excrement is also abrasive. While it’s fresh, you can easily wipe it off. But that’s not that smart. You can scratch the paint. Use a soft cloth dipped in a car cleaning product. Place the cloth over the poop and let it sit for 30 seconds. This will dissolve the acid and pick up the abrasives. Then, just wipe away the poop.
  • Use bird poop wipes
    There are wipes made specifically for cleaning bird poop on cars. These work great on fresh poop. Not that good on dry poop though. The wipes are really soft, made with materials safe for car paint. Just wipe away the poop with the wipes.

Cleaning Dry Bird Poop

Dry poop is harder to get rid of because it’s stuck on the car paint. Trying to scrub it without loosening it up first will cause damage to the paint.

  • Use WD-40.
    One of the most effective products for getting rid of bird poop is WD-40. It’s a multi-purpose product that can be used as a lubricant too. Just spray some WD-40 on the droppings and let it sit for 2-3 minutes. Once the poop has loosened up, wipe away with a clean cloth dipped in clean water.
  • Use Bug & Tar Remover
    Another multi-purpose product that can remove and hard-to-get-rid-of particles on your car. It works the same way as the WD-40. Just apply it on the droppings, let it sit, then wipe away.
  • Baking soda and hot water. 
    You can make a homemade bird poop remover using household items. In a spray bottle, add 2 tbs of baking soda, 1 tbs of dish soap, and warm water. Spray the mix on the bird wastes and let it sit for 10-15 minutes. Once soaked, wipe away with a clean cloth.

Any of these will remove dry bird wastes. A simple solution to get rid of bird droppings. Remember, you should wash your car after using any of these products.

How To Protect Car From Bird Droppings

  • Use a car cover. 
    In my opinion, any car that is stored outside should have a high-quality car cover. Something with UV protection, bird droppings, and tree sap protection. Breathable fabric as well.
  • Don’t park your car under a tree. 
    Most of the poop that sticks to your car comes from a bird on a tree. Birds rarely fly out in the open and drop poop. So, just don’t park under trees where it’s obvious that there is a nest there. It’s better to give up the shade than to have your car covered in poop.
  • Have bird poop wipes on you so you can remove droppings quickly.
  • Add Clear Bra, wax coating, or ceramic coating. 
    The best way to protect your car paint from any damage is just to add a protective coating. If you don’t neglect your car, the coating will endure droppings for up to a week.
  • Wash your car regularly.
