Had some bird **** on my car today, it was probably only on the car for no more than a couple of hours. I came home and washed it off, however, there is now a stain left there, looks like the acid of the **** has left a "burn" mark in the paint.

I've had this a couple of times before on previous cars, makes me livid!

What is the best method for removing this stain? Or will it remain for ever more?

I tried some AG Rapid Detailer on it but that had not effect.
 
Absolutely as Gaz says sounds like it needs a DA on it with some fine cutting compound.
 
Try Menzerna SF4000, its a fine degrading polish so only a mild cut that degrades into leaving a polished finish with no scratching. Although in all honesty it depends how much the acid from the bird muck has eaten into the paintwork, it may well need a DA on it as Rob and Gaz say above

Cheers guys. I don't have a DA so can these cutting compounds be successfully used by hand? My car is sepang blue.
 
Something like megs swirlex should be fine by hand on top coat lacquer, even T cut maybe

I've totally stopped using T-cut it leaves a matt area to the lacquer.

Haven't tried it myself but there is plenty information on the web about people using a hair dryer or heat gun.

Do you think diluting tcut with polish would still be too harsh for polishing out bird dropping stains on flat black?

As Rob says, plus T-cut will leave swirls as it is not a de-generating cutting compound, so using it will make the problem worse not better

I use cloth moistened with hot water, clean the poo off and hold the cloth on the affected area for about 30 seconds then leave it for a bit and repeat again if needed.

+1 damn cloth in the microwave for 30 sec lie it on top, take everything off with leaving anything behind.

Oh and T-Cut is the work of the devil.

once the poop is off what is left is etched clear coat not a stain, its pitted on a microscopic level, you need a very slight abrasion to level the surface again to bring the gloss back, so you need a fine polishing compound, you could use t cut but at is course in its abrasion (diluting it doesn't make it less course, it just increases volume) it will get it levelled quicker by hand but you then need a fine polishing compound to bring the gloss back. with any polishing or sanding process the harshest abrasives do the most work but by their nature they leave fine scratches so you have to go through a series of harsh to fine to perfect the job.

Thanks again guys. I've just tried some Autoglym Ultra Deep Shine polish. It's helped git rid of some of the etching but you can still see it when you look at it from certain angles.

Try the hot cloth method a couple of times and then leave it. My last one took nearly two days to go.

I used up my t cut in bringing old white upvc windows back to life - worked very well on them.

The hot MF towel I learnt from the above guys and works really well.

The only people who could use Tcut work in the paint shop. Its hugely aggressive and is ideal for an inter coat rub down. If you have any in your garage or shed chuck it away. Whether you dilute or not the particle size doesn't reduce you just get less of them.

I agree with swirlX. If that doesn't remove it I'm afraid your going to have to put up with the mark.

I know exactly what you mean, it's like a clear scab on the surface of the paint?!?

I tried everything I had and it was still there! Then I got some Meguiars Ultimate compound on a microfibre cloth and it came straight off! I'd initially bought the UC for some light swirls and scratches to use with the DA, but it's also good for what you want it for!

When I see poop on the car I get a damp MF cloth, put it in the microwave for about 30 second and then leave it on the offending poop for 30 seconds, comes straight off then. (Think it was Scott that gave me that tip?!?!?)

Has this ever damaged your paint work?

I just did this with boiling water from a kettle onto a MF cloth and held it on for 10-15 seconds and it disappeared!
 
The dealership I used to work at used the hairdryer method to get rid of all sorts of marks
 
Pressure washer with soap, then clay bar with enough lubrication.. very light pressure and I have to emphasise lubrication if not you will leave strike's.
 
Heat pulls out the stains.

As mentioned above hair dryer or heat gun, but don’t burn the paint!

Take it easy.

The other option is to stick a microfibre on it and put some boiling water on it, to draw it out.

I have problems with bird poop due to some terrible neighbours with a mega sized bird feeder that is keeping the neighbourhood pigeons nice and plump. My car is in the flight path.

I use andrex wet wipes (must have in the glove box!) as soon as I spot them, but I've had a few marr my paint before I found a chemical resistant sealant that works.

To removed burned in ones I've found Farecla G3 scratch remover (the one on the bottle not the tube) on one of their white hand applicators usually will take it out. It is a diminishing abrasive, so you need to work it for a while until it breaks down smooth and brings back the shine or you will leave dull spots. But it works very well if you follow the directions. Baring that some wet standing with 2000 grit and then following up with the G3 works.

G3 resin wax and autoglym super resin wax did nothing to stop the marring. I've since gone to meguiars hybrid ceramic and and having no problems with burn in now.

I only wish I could kill the pigeons... or the neighbours...

I have the same problem.
I feed the local gold finches, unfortunately the pigeons feel they need to be in on it.
Sometimes upto 6 of the big horrible things hoovering up the spilt sunflower hearts.
Obviously it has to come out of them, and that is usually after a car wash.
Drives me nuts it does, but hey ho that's why I use a garage.
If I do find any poo I use a warm water soaked kitchen towel now

I use sunflower hearts, reason being, they don't germinate and grow when they reach the ground, so no unwanted jungle can grow, pretty sterile.
Pigeons though, they are like seagulls, they will eat anything.
And equally as dumb, forever trying to fly through our kitchen window pain :haha:
 
As I say they dont seem to bother with what lands on the floor. I would rather have a patch of seedlings than **** on my car.
 
Hi All,

Apologies for reviving an old thread. Never had this issue before. Found a bird poop max 4 hours and all baked. Removed it with Auto Finesse detailer. But it had left a stain on the front bumper. Will i be ok to use hair dryer on bumper? Going to grab Meguiars Ultimate Compound from local halfords tomorrow. I clay bared the effected area and used menzerna sf4000 with german pad (by hand) it faded the stain but its still there. It might not be an issue for some but i know its there and really annoying as almost clean them asap dont know how i missed this ******* poop.
Thanks

Sal

Poured directly on the effected panel or using the microfibre cloth as mentioned in above posts ?

I've poured it directly onto the **** and then wiped it off with a towel, no issues ever.. actually just done it.
 
Is this something to do with the type of clearcoat audi uses ? I have had many makes of car over the years, but is seems very susceptible to bird poo burns. Even if it's only on there for a couple of hours, it burns the coat. To compare with my last , I had a black Bmw, and that paint on that was so hard.......never had a problem with bird poo stains or tree sap marks.
