I might have explained before that the make up of the bonds between the tar particles are pretty similar to those of a sealant or wax. The hydrocarbons in each will be broken down in the wax and in the tar, if you use something like tardis.
If you can flick them off gently, or try using a quick detailer and a clean microfibre very gently to remove it. If you use a dedicated tar remover it will remove the wax in the surrounding area, so there best left alone.
