 Okay, so what are the materials that are typically used? Is it a bleach type? Yeah, usually there's a bleach type material. It's an oxygenated bleach type of a product or it's a diluted bleach. There are a number of commercial products that are like that that are out there. There's 30-second cleaners is one of them. And you have to apply it and you have to let it sit because it will kill the mold spores and then you rinse it off. But it's a process, you know, and there's a lot of elbow grease involved.
