Steps:
Spray the solution directly on the mildew patches.
Let it sit 10–15 minutes to kill spores.
Scrub gently with a sponge or brush.
Rinse thoroughly with clean water and dry the wall completely.
Step 4: Prevent Future Problems
Identify and fix sources of moisture or leaks.
Use dehumidifiers or proper ventilation to reduce indoor humidity.
Apply anti-mold or anti-efflorescence paint if necessary.
Regularly inspect walls for early signs of saltpeter or mildew.
