Step 1
Apply a warm soapy cloth against the adhesive to initially soften it up.
Step 2
Drizzle baby oil over a cotton ball to moisten it. Rub the oil on the adhesive residue stain on the shower door. Allow it to soften the glue for five to 10 minutes.
Step 3
Scrape the adhesive stain with a plastic scraper to lift off the glue. Wipe the adhesive onto a paper towel. Continue to scrape to remove as much adhesive as possible.
Step 4
Wet a cotton ball with nail polish remover. Buff the remaining stain with the nail polish remover to break down the glue. Rub the cotton ball back and forth as the adhesive glue balls up. Use another cotton ball, if necessary, to remove the remainder of the glue.
Step 5
Fill a spray bottle with white vinegar. Spray the shower door with the vinegar spray to remove any remaining adhesive and residue from the baby oil and nail polish remover.
Step 6
Wipe the bathtub shower door with a paper towel to dry it off.
