I have done that gawd awful job. We used a two part poly-sulfide. Some of the tools I used was sharpened flat head
screwdrivers (three or four) and a cool tool that is probably similar to what slowshoes is talking about, kinda like a flat head
screwdriver but with a v shaped end (?). I'd use the v shaped tool first then the flat heads to get the bits and pieces. I would hit my tools with a sharpening stone a lot (they seem to dull quickly). A strong
vac is a must, taping off, and covering everything that may be walked on (inside and out) or touched by caulk tainted hands (handholds etc) will help with clean up.
