Can I sand the remaining caulk off the aluminum/vinyl around my window and paint
Hi DIY Community

I am stripping some old caulk out of my window so I can re-caulk it but in the process I am scratching the hell out of the aluminum and vinyl siding around the window. The caulk is so old that it has turned black, lost itís elasticity and it is chipping out in very small pieces. In some cases I am using a razor blade to scrape it out. That being said, it looks like hell. I can get it out but I canít clean it all up.

Can I just sand the aluminum/vinyl siding to get the rest of it, then paint the ugly spots with matching paint?

Or does anyone have a better idea.

Thanks in advance for your help.

Need some pictures to see what it is your up against.
Often the black is from mold and can be killed and cleaned up with bleach.
Once you scratch the siding there's no fixing it.

I attached a couple of photos. On one of them you can see the black caulk on the other you can see the mess that is left after the caulk is removed. The aluminum is scratched up and it's a big mess. Any ideas?

scrape the boogers; mineral spirits to wipe the remainder

Thanks TarhellTerp. Will that strip the paint off of the aluminum and is so, can I repaint the aluminum or should I just add new aluminum.

The aluminum can be painted - clean it - hit it with "deglosser" -
get good paint.
Mineral Spirits should not damage the vinyl siding - depending on the siding!?!

I bought my Mineral Spirits, Deglosser and paint. I will let you know how it goes. BIG thanks for the responses. :)
