The word killer always puts me on the defensive. I immediately feel like this product is going to claim to kill mold on contact without the need to actually remove the mold as well.
Moldex Mold Killer is an EPA registered 3-in-1 cleaner designed to kill, clean and inhibit the growth of mold and mildew.
It destroys and neutralizes mold, mildew and their odors at their source. It is not a masking agent or general purpose stain remover. It’s bleach-free, phosphate free, non-abrasive disinfectant mold killer.
When I was researching Moldex I found an interesting blurb on the Rust-Oleum website (the parent company of Moldex) about Mold Killers vs. Mold Removers. Here are the highlights:
Experts say you need a two-part strategy for mold – kill it and clean it.
‘Killing mold and mildew growth requires an EPA registered biocide,’ says Brian Joyce, brand manager at Moldex.
Moldex Mold killer is a biocide that disrupts the life cycle of mold and protects against new growth. Just as a weed killer is designed to kill weeds, once the plant has died, you need to remove the dead biological growth to finish the job. In order to ‘lift’ or ‘remove’ what’s beneath the surface (mold stain) after the organism has died, you need a powerful cleaner.
Removing the Stain…
Most stains are removed by dissolving them, but the effectiveness of the cleaner depends on two factors: the cause of the stain and the material that has been stained.
‘Different cleaners dissolve different stains. Moldex Instant Stain Remover is a bleach-based product that removes difficult mold and mildew stains on surfaces that are bleach-friendly,’ Joyce explains.
So you really need both a killer and remover?
Yes. Stain removers lack the ability to effectively kill the living organism that causes mold and mildew.
‘Do your homework,’ Joyce says. ‘Ask the representative at your local hardware store what they recommend. They should know the difference between a mold killer and a mold stain remover.”
Not only is the bulk of this information incorrect but the advice to speak with someone at a hardware store about mold is reckless. Typically they don’t know much about mold.

Toxic or Non-Toxic
Not completely non-toxic as Moldex does have a teeeeeeeny, and I mean teeeeeeeny amount of the dreaded dimethyl benzyl ammonium chloride. I have yet to meet a product with this small amount in it. So I would say that Moldex Mold Killer is safe as long as you don’t swallow it.
Final Verdict
I’m not confident in Moldex and would not suggest anyone rely on this for their mold problem. But if you would like to purchase it, you can find Moldex Mold Killer here.
