What is the best swab to use for high temperature applications, like cleaning out a hot mold?

The head of a foam swab with degrade, tackify and breakdown around 275°F. The polypropylene handle will melt around 320°F. A better option to resist the degrading effect of the high temperatures is a polyester swab head on a nylon handle such as 51353, 51121 or 52121. 52121 would probably be the best, because it’s 6 inches long which keeps more safe distance between the hot mold and the user. It should be able to handle temperatures approaching 500°F.
