How do I make a mold cleaner for house?

Jo-Max works great - better than mere bleach- & inhibits future mold growth too. When you paint next be sure a fungicide is added to pain at least on sides where it gets mildew/mold - north side probably worst...

Use a 50/50 solution of white vinegar and water on mold. Do NOT rinse it off since it will leave an acid base where the mold was and help prevent it from growing back.

mix bleach and water or all bleach

I use bleach soaked cotton to remove mold stains, and vinegar to clean!

Hello Irene, this may help you To kill mold: Use white distilled vinegar and pour it into a spray bottle without watering it down. Spray the vinegar onto the moldy surface and leave it to sit for an hour. Finally, wipe the area clean with water and allow the surface to dry.
