Well i left my car at my dads house for about a month.
he left it in the garage with no car cover on.
well i got it back today and it was really dusty so i though no problem ill just wash it when i get home. so i drove it home and began to wash it. when i began to dry it i can see that theres still dust on the paint. it wont come off.

is there anyway i can get rid of it? =[
and my car is black so you can really tell =[

 

Try a product from Meguires called "Clay Bar" it can be used to clean your paint.

 

yeah try the xtra fine clay bar, was the car recently painted? paint stays soft for a little while the cover probably would have left marks too

 

it was painted in june. so its been a few months.

 

That's odd that dust wouldn't wash off. Do you think it is some kind of over spray? The first thing I would try is to hit it with a fine polishing compound and a buffer. If you don't have a buffer there are products that are made for hand polishing. If it is a light oxidation it should come right off with out much rubbing, and then a nice wax job to seal it.
