The process is time-consuming and requires a lot of patience, but the hard work is worth it and changes the tub’s look entirely. We’ve compiled everything you need to know to learn how to remove old caulk from bathtub surroundings.

The Purpose of Caulking and How To Remove Old Silicone Caulk From Tub?

Caulking is an age-old method used for centuries. The material is a waterproof filler that offers a watertight, airtight, and non-absorbent seal. This sealer prevents air, steam, gas, water, or other liquid materials from passing between two substances.

Various household areas like floors, attics, walls, etc., use caulking; but it is primarily used in a bathroom where water usage is higher. Silicone caulk is exemplary for situations where water damage might take place. Water leakage is a common problem around sinks and tubs if not caulked and reduces the longevity of the parts by continuous penetration. Because of its rubber-type consistency, silicon caulk ensures a watertight seal to keep your bathroom protected.

Interesting Historical Background

The idea of caulking was first evolved by mariners centuries back. Caulking is a crucial task for the ships to avoid sinking caused by water leakage in the joints of the ship. Of course, no fancy caulking material was available at the time. They used to apply melted pitch on the critical joints of the ship to avoid any water penetration and keep the ships floating.  But it was not easy to always keep the pitch hot. The sailors had to struggle with the elements like rain, wind, storm to keep the hot pitch functioning.

There is a common phrase we all heard of, “There is the devil to pay.” This phrase originated from this caulking method. The major points were named “The Devil,” and paying means putting a hot pitch on it. We should pay tribute to those brave sailors whose hard work has eventually led to the usage of caulk. Now caulking can be done in the easiest possible way to keep our belongings protected.

Types of Caulking Material

The primary function of caulk is to seal the gaps between the exterior and interior of household surfaces, especially those prone to water damage. However, a wide variety of materials are used for caulking, such as:

  • Silicon: This is the most durable. It can be used on metal, ceramic, wood, and fiberglass.
  • Latex: Latex is suitable for indoor use only.
  • Acrylic Latex: It is suitable for both indoor and outdoor use.
  • Butyl Rubber: This form of rubber is suitable for covering wider gaps up to 1/4 inch.
  • Oil Based Asphalt: For heavy-duty repair jobs, asphalt works the best.

The Need for Caulk Removal

As advertised, most silicon caulking products are supposed to last at least 20 years. But in reality, that rarely happens! Excessive moisture causes the caulk to fall off prematurely. Apart from the functional problems, it creates a nasty look with the half ripped off caulk, which is significantly discolored with dirt. No matter how expensive your bathroom fitting is, the weary silicone caulk will ruin the aesthetic!

Also, if the caulk is damaged, it means the seal is broken, and water penetration will occur throughout the bathroom, creating a slippery floor and risking the user and damaging the fittings over time. So there should not be any delay in re-caulking for your safety.

Caulk Removal Process

  • Needle-nose pliers
  • Toothbrush
  • Dry paper towel/microfiber

Removal Process

At the beginning of the process, you have to apply any caulk remover or surface cleaner to make the caulk turn soft. Though the directions on the package will tell you to keep it 2-3 hours, it’s safe to keep it overnight for easy peeling off.

Then, grab a utility knife with a sharp blade and remove the caulking from the tub little by little. This step has to be done very carefully because if the knife slips, it may damage the tub’s surface. The good thing is that silicone caulk is usually easy to peel off.

Small broken pieces might still be left behind even after cutting through. You can use needle-nose pliers to remove the remaining caulking.

Cleaning Process

Upon completing the peeling-off process, merely use a toothbrush to scrub away any remaining residue.

Use a light amount of surface cleaner or liquid soap on a dry paper towel/microfiber and wipe off the area. Some people prefer ammonia-based cleansers, but that should be strictly avoided. Because, in later steps, bleach will be used and combining ammonia with bleach creates a toxic fume.

The final step is to clean the mildew. You can clean the mold by preparing a solution of bleach and water. The recipe is – 1/3 cup of bleach mixed with 1 gallon of water.

Spray the solution on the surface and scrub it. Then wipe it off using a fresh microfiber.
