My friend could not clean off the goose droppings as they dried and pretty much baked in. Does anyone recommend a cleaner to use. I was thinking about the clay kit which i want to get to clean my car of the dried specs on my own car. Would that clean the dropping?

 

Try a clay bar or meguiars scratch remover.

 

Carefully. I wouldn't use a claybar to initially remove the contaminents since you risk the dropping actually scratching the surface. First you need to spray a cleaner on them while the car is cool. let it sit there to "soften" it up. This may take several applications. I have personally had to use my finger to "work" it into the bird crap myself. Not pleasent, but if you aren't careful removing it, you risk scratching the surrounding areas. Once the droppings are good and soft, use a microfiber towel to gently "blot" them up (don't wipe back and forth, again, you will risk the chance of scratching any surrounding area) It may take a little while to blot the dropping completly up.
Once you have removed the actual droppings, you will most likely have a spot etched on the paint. Depending on how long the droppings have been sitting on the surface, even after thoroughly cleaning the area, you may still have acids eating into the paint/clearcoat. Seriously. I have cleaned and refinished a bird dropping spot on my paint too soon only to have the spot return a couple of days later. Very frustrating.
I usually have to do an intial cleaning to remove the physical contaminents, then wait a couple of weeks to actually refinish the paint surface since the acids are still working on the paint. If the etching spot isn't easily removed by a standard Scratch-X or equivalent paint scratch remover, you may want to try a 2000 grit followed by a 3000 grit wet sanding followed up by Scratch-X (or equivalent) followed by a good coat of wax afterwards. Don't over wetsand...

 

Soak it first for 20 minutes. Put a paper towel over it and put clean soapy water on it. Leave the towel on it for 20 minutes. Tat should loosen it up. Than you can use clay bar.

 

As Austin said, once you carefully remove the dried crap, you are almost guaranteed to find etching/chemical damage. Just remember, bird crap=acids.

Having said that, unless you're handy with a polisher, you may want to have it professionally done. I wouldn't wetsand it either unless you've done that before, or there's a good chance you'll fugg the paint.

 

I always used dish soap and a soft cloth or rag after soaking the poop for a while with a little bit of soap and water. usually comes right off as long as you don't scrub real hard - you've got to get the crusty parts out slowly.

 

Thanks, all. I am going to buy the Meguair Clay Kit to clean my own car before lending it to my friend. Hopefully your suggestions will work for her.
