tool, cut caulk away from the surface 
and peel away as much old caulk as 
you can.

a stiff brush or scrubby sponge, scrub all 
remaining silicone oils and residue from 
surface. Do not use mineral spirits.

acetone or silicone remover again to 
remove any remaining oils and 
residue. Let dry completely.
