Method One: Using Ammonia
Step 1: Ventilating the Place
For this, you are going to need safe ammonia. These are pretty harmful to health. So, make sure the place you are working at has enough ventilation support.
You can simply open the windows and doors widely so that there’s enough air circulation going on. Also, turn on the fans or set up handy ones to get moving air.
Step 2: Protection from Fumes
The airflow inside a bound space such as a bathroom is often too limited. It invites a high risk while working with ammonia. So, you should wear the right respirator before doing this job. It will help in filtering any hazardous fumes.

Step 6: Using Another Cleaner
You may feel mold has gone away, but that’s not necessarily the case. Sometimes even with clear looks, the shape is still present on the surface. It could just reappear after a while. If that’s the case, then ammonia is not capable of going deep into such serious mold roots.
So, you will need to try another solution.

However, if the mold is tough, using sponge won’t help much. In such a case, fill a spray bottle with the solution. Mist the solution over spots and let it sit for five to ten minutes. Once the solution settles use sponge to wipe it down again.
You can use a cleaning brush by spraying once again if there’s still residue remaining. The solution needs some time to reach mold’s root. Use a bristled brush after letting it settle with the mold well.
Step 3: Treating Deep Rooted Molds
If the slight effort doesn’t seem to work, go for hard ones. In such a case, use cotton coils. Let them soak thoroughly with the solution.
Now place these coils over caulk line. It needs to nudge them and so use Q-tip.
Let the caulk sink in for one night. And then you can simply scrub it away in the morning. This will should work to remove mold from caulk naturallywithout using too harsh cleaners of hard stains. These are also helpful to remove rust without harming underneath sealant.
Use a paper towel or washcloth to wipe down that area after scrubbing with the solution once again. There could be active agents still breathing on that surface. Rubbing a final time will prevent mold from growing once again.
