How much mold can I clean myself?

Figuring out how much mold you can tackle on your own is a common question. The general guideline is that if the moldy area is smaller than 10 square feet, you might be able to handle it yourself. Think of it like a small stain on a wall. However, this is just a starting point. Several factors determine if DIY mold removal is a wise choice for your situation.

When DIY Mold Removal is an Option

If the affected area is indeed less than 10 square feet, and it’s on a non-porous surface like tile or sealed wood, you might be able to clean it up. Non-porous surfaces mean the mold isn’t deeply embedded.

Protective Gear is Non-Negotiable

DIY Cleaning Methods (For Small Areas Only)

If you’ve decided your situation is a safe DIY, here are some common methods. Remember, these are for small, non-porous surfaces. Always test a small, inconspicuous area first to ensure the cleaning solution doesn’t damage the material.

Baking Soda Paste

What NOT to Do When Cleaning Mold
