Information regarding home maintenance focuses on methods for removing and preventing mold growth on various surfaces. For tiles, ceramics, glass, or metal, water and all-purpose cleaners are generally effective. On plastered or painted walls, superficial spots may be treated with household cleaners, though the Verbraucherzentrale Niedersachsen suggests using 70% to 80% ethanol to kill spores. In bathrooms, hydrogen peroxide mixed with water can be applied to surfaces for 20 to 60 minutes before scrubbing.

Prevention strategies emphasize regular ventilation and reducing humidity. In enclosed spaces like closets or drawers where odors persist, cleaning surfaces and using baking soda in an open container can help absorb smells. Professional assistance is recommended if mold growth exceeds half a square meter or is not merely superficial.
