•

If sealant has hardened, it has rubberlike properties (like an eraser), and
may come off easily by rubbing with a
dry towel.
If the cured sealant does not come
off, rub it with a wet towel for about
1-2 seconds and then rub off with a
dry towel.

NOTICE
Prolonged contact with a wet towel may
spread contamination.
