It is going to take some long, detailed, careful work to remove embedded anything from the edge of a clearbra...
They make some really nice square soft detail brushes that can help remove it when its deep in there....
Something like this -
SM Arnold Vent & Dash Detail Brush w/ Horse Hair Bristles, Yellow
Before you use this or any brush that close to the paint, you need to put a couple layers of black plastic tape over the entire metal ferrule on the brush, so it wont accidently scratch anything, ok ??
The hard part is doing this without leaving tiny scratches on the paint there or the top of the clearbra.... Hence, the long time its going to take...
But You Can Do IT ! I have done dozens..
Sometimes, a good wide fan tipped pressure washer can help get this out - but you have to be really careful - spray it from a good distance to see what happens...
Get closer until you find just the right place....
You cannot use a pressure washer in high 2+ - 3gpm range on this ever... Has to be around 2gpm or so or smaller...
Now you know why I always apply Anything on a clearbra starting at the other end carefully, and working toward the edge from the BACK, and Never, from the opposite side of the Bra working Toward It - ever....
And when you get to the edge, you lift up and try not to hit it with anything with pressure...
Sorry you have to do this... It will look Fabuloso when its all cleaned out and then you lose the edge almost completely in the paintwork...
Good Luck !
