Thread: Cleaning Bird ****, Insects & Gum Tree Stained Water off Paint

"Australian mistletoes spend a life airborne on a host tree's branch, and very briefly, inside a bird.

That bird is a flower-pecker named, helpfully, the mistletoe bird. It's as small as a sparrow and must have one of the fastest digestive systems in the country. It's apparently 14 minutes from go-to-whoa, and they eat any mistletoe fruit they come across.
Their poo comes out sticky and full of seeds, and — here's an interesting thing — when they feel the urge, they turn their body along the branch rather than off it. They deposit the seed directly onto the tree instead of onto the ground, or your car below." from The bulloak jewel butterfly and how the web of life affects us all — from mistletoe to humans - Science News - ABC News

Bird poo is pretty nasty stuff as it is corrosive and it will strip the paint off cars and boats, Then we have bat poo which is pretty much the same as bird poo But it also smells pretty nasty as well.
I find that hosing the majority of it off and letting it soak few a few min will soften it up then wash the car/boat with truckwash which will remove it But you have to do this regurlary otherwise it will start to eat the paint away.
