Removing caked on old bug guts

As if keeping 1 black car clean wasn’t enough, we bought my wife a new (to her) car 2 days ago.

1003171


Three years old and overall very clean - with the exception of the caked on bug guts on the front. I’m convinced the previous owner never cleaned the front of the car.

I tried one “bug and tar” remover stuff from Autozone that I had bought for my car but it only got maybe 30% of them.

Anyone know of any secret sauce for removing petrified bug guts?

PS: this is Challenger related because my Challenger has some similar stubborn bug guts that I’d like to remove - though not nearly as bad.

Looks like WD 40 also works for tar. I'll have to try that the next time I wash the scat.

How to Clean Tar and Bugs Off Your Car.

  1. Ivory soap is another excellent way to remove vehicle areas covered with bugs. The stearic acid in Ivory soap helps to penetrate bug residue and with a little rubbing the bugs will come right off. Simply wet a towel and rub the bar of soap onto the wet area to create a paste, then rub those areas with bugs. Repeat as necessary.
  2. Believe it or not, clothes dryer sheets have proven to be effective at removing bugs from bumpers and wheel rims. Simply take a dryer sheet (recycle a used dryer sheet, this works just fine), wet and begin rubbing. With a little soaking and rubbing, bugs should come right off.

Thanks guys. Just finished trying both WD-40 and dryer sheets. Both got me closer - but still quite a way to go.

Some other internet surfing tells me that my next step is likely a machine polish w/at least a finish compound. These suckers have apparently been dead there for quite some time and I believe the acid from the bugs has stained/damaged the clear coat.

Be glad they weren't love bugs. They'll destroy paint in hours.

Look at videos on YouTube you spray it on then hose it off then wipe the car off body shop charge big bucks did mine 2018 and have not waxed the car since water runs right off and bugs won’t stick to the car

This is good stuff


But I don't think any bug remover will fix years of neglect. A coarser clay might also help, but will usually mar the paint requiring polishing, but that may be inevitable anyway.

It may take an aggressive compound, or even a 2500 wet dry sandpaper, followed by a polish. If the acid has etched all the way through the clear coat, then only making it look better, not fixing unless sanded and painted/cleared. Some Bug Squash mixed with water in a steamer may also assist you to remove the majority of the carnage itself

I have two pretty good ways to get bugs off a car.

1. dampen a towel with hot water and lay it across the area to be cleaned, remove once it's cool to the touch. Leave the bug for a few more minutes than wash as normal. Rehydrating the bugs makes all the difference in getting them to come off.

2. If you're in a hurry. Bleach White, for cleaning tires. Spray on the area to be cleaned them scrub with a bug sponge. Wash the area with car soap and re-wax as the bleach will remove the wax from the paint. It is safe on plastic as well, just make sure to not let to dry with the Bleach White on the surface.

I use Super Clean diluted 5:1 on the front grille, then foam over it and pressure wash it off, gets 90% off and the rest wipe away easy with whatever car soap I'm using to wash.

FWIW, the best thing I have found for bug guts is getting caught at highways speeds in a torrential downpout.
And a good frequent wax coating up front helps, but once they are baked on over time, elbow grease is about it. I like the wet a towel and let it soak method, I bet that works well.

This is the worst any of my cars ever got, that was 1 days drive up to the "Angle Inlet" of Minnesota through Canada.
I don't even know what some of them were, like hornets the size of butterflies.

But I did have to deal with Florida Love Bugs on my honeymoon many decades ago, I don't like bugs.
