Remove the loosened caulk with
a putty knife, pulling it out from
the gap between the tile and the tub.
Scraping out moldy caulk from
around a bathtub is a tough,
tedious job. And if you get too
aggressive, you'll chip a tile or mar the
tub finish. Make the job a lot easier by
first softening the caulk with a caulk
remover (inexpensive at hardware
Application is simple. Just squeeze
the remover onto the caulk, making
sure it covers the edges (Photo 1). Let
it sit for several hours (or as directed
on the package). Then start scraping
out the old caulk (Photo 2). The caulk
remover works by destroying the bond
between the caulk and the tub or tile,
so that instead of chipping at the caulk
with a razor blade, you just pull away
big chunks of it with a putty knife.
Most removers work on both silicone
and acrylic latex caulks.
Clean off the residue with soap and
water, let dry and then recaulk.
