Ammonia can clean mould from hard non-porous surfaces like countertops, tiles, or glass but it is ineffective at stopping mould growth in porous materials such as drywall or wood. One of the biggest disadvantages of using ammonia is that this substance is highly toxic. When using ammonia to clean mould be cautious and use gloves, facemask and safety gaggles. Never mix bleach and ammonia – they release poisonous gas when combined.

Bleach is very effective in killing mould spores and removing mould and mildew. After using bleach the surface is sanitized and resistant to mould growth. Unfortunately, just as with ammonia, bleach is only effective on non-porous surfaces and materials. It works great on tiles, mirrors, glass, countertops, sinks and bathtubs. However, when used on porous materials such as drywall or wood, bleach cannot reach beyond the surface – the spores within the material remain and the mould soon returns.
