Successful Bathtub Caulking
Caulking is an easy home improvement project that can deliver very attractive results.
First, use a "caulk softener" to help soften and loosen the old caulk making it easy to remove.
Then, wipe down the areas you have removed the old caulk from with a bleach and water solution to clean and kill any mold spores left behind.
Finally, fill the tub with water before caulking. Then, after the caulk dries, drain the tub. This compresses the caulk so it won’t fall out.
