Let’s be honest — there’s nothing quite as gross as seeing black or green streaks creeping along the edges of your tub or shower.
It’s not dirt.
It’s not soap scum.
It’s mold and mildew — thriving in the warm, damp corners of your bathroom caulking.
And if you’ve ever tried scrubbing it away with a toothbrush and a prayer?
You know how frustrating it can be.
Most cleaners just smear it.
Scrubbing barely helps.
And replacing the caulk? That’s a whole weekend project.
But what if I told you there’s a simple, two-ingredient method that lifts mold from caulking — no scrubbing, no fumes, no renovation?
Let’s explore how to banish bathroom mold using just bleach and cotton rope — a genius hack shared by cleaning expert Jessica of This Blessed Life.
🧪 Why This Method Works So Well
Traditional scrubbing pushes mold deeper into porous caulk.
But this method uses bleach saturation — letting the solution sit and penetrate over time.
The secret?
Cotton rope (or cotton coil) — a long, absorbent strip that holds bleach directly against the moldy line.
It works like a slow-release treatment:
The cotton soaks up bleach
Lies flat on the caulking
Releases the solution gradually
Breaks down mold at the root
No scrubbing.
No harsh scrubbing.
Just clean, white caulk.
