Removing Mold From Grout

I received an email from a customer today regarding mold removal from the grout in the shower. What we usually do is have one of our sales guys or tech answer the question and post it to our blog so people in need of information can use it for help later on.

Since mold removal is not our specialty, and I know there are already posts on this, I would like to try something new. JB is full of people that really know there stuff. If someone is willing, I am looking for someone to respond to this as if they were giving directions in an informative article so we can post it on our site.

Whoever posts or adds to the information, will get full credit, a link to their company's site and we will link back to this thread with full disclosure and support for the JB forums.

The only information I have so far, it a green stain on the grout right outside the shower. It is about the size of a pencil eraser and was not sealed since it is not inside the shower (but still susceptible to getting wet).

Thanks in advance everyone!

Hi Daniel

As you already know, mold is a tough topic to address. I learned in a seminar a while back to refer to it as BOG (Biological Organic Growth). There is no set solution. Some is established on the surface, such as perimeter caulk joints, caused by entrapment of soap or shampoo residual. Other can be subsurface, such as appearing on the surface of the grout, but actually starting on the paper surface of wet drywall, thus it's constant reappearance after cleaning.

Lastly, the worst case scenario, I will call internal. One example is when extreme moisture is present in a wall cavity, and various types of mold are growing (some of which is toxic and can severely affect the health of sensitive individuals).

This is when a mold remediation team must be sent in. If contractors uncover this type of situation, it is their duty to notify the homeowner of the situation, and hire a mold remediation team. It will be the contractors liability if he doesn't take the appropriate action.

The scenarios that I have described above are why there is no simple solution. While they vary from mild to extreme, IMHO, they really require an on site visit to determine the cause of the growth to give accurate advise on possible remedies.
