Method 1: Cleaning Caulk Using Bleach

Out of the three modes, this is the most common and heavily used formula. I'll discuss the whole process on a step by step basis.

Step 1: Take Precaution

Before starting the cleaning process, you must have to take precaution first. Bleach, Ammonia and Mold Killers, all of these chemicals have harmful effects on the human body if it is touched.

Wear a full-body safety suit, safety goggles, face mask, and the hand gloves to protect yourself from the bad effects.

A gentle reminder, since bleach is very reactive to the color of clothes, wear an old cloth so that you do not ruin a fresh cloth with it.

Step 2: Make the Mixture and Fill the Spray Bottle

Make a mixer of 250 ml bleach with 4 liters of water. Use a stick to mix the bleach with water entirely.

Fill the spray bottle with the bleach-water. Try to make some room in the spray bottle so that the air pressure remains even. Full bottle water can cause complications spraying the liquid.

Step 3: Spray to The Surface & Let it Sit

Spray the liquid mixer on the moldy caulk. Try to avoid spraying on the normal surface area of the shower or bathtub.

Let the liquid sit for an hour or so, and then take the brush to scrub the mold. When scrubbing the caulk with the brush or tip of the caulk gun, cover your body as much as possible.

Step 4: Rinse with Water

Rinse the caulking with tap water thoroughly and get a fresh new-looked shower in your sweet home!
