I work on an industrial estate which has a terrible seagull problem. This means my car gets lapsed in bird poop regular as clock work. I used to have to get all the hose out when I got home etc etc. Since using this product I just carry it in the car with some microfibre cloths. If I get something I need to remove just spray it on and it blasts a lot straight away straight on contact. Catch the run off with the microfibre cloth wait a few seconds and just do one sweep back across the area and usually does the trick. This is definitely the best product , for this type of job, that I have ever found .
