After you have removed the contents from the home and open up the walls, you’ll see areas of mold, typically. There’ll be other contaminants from flood waters. You want to use water initially to get off as much of that after the water first comes in. You’ll physically remove it with water. Then, after that, you can use a water detergent solution. You want to read the label on that product to make sure you have the right amount. The detergent products will be more effective if you do that initial washing with the water and then come back later with a detergent-type solution.
Consider using a two-bucket type system. You can use any number of different brushes. Use the solution in one bucket, a clean solution, and then a rinse bucket in the other. That is a more efficient way of cleaning. You can use pressure washing during the process, but using a high-pressure washing system sometimes can cause more damage than good. So, you want to be aware of using not too high of a pressure of water.
Then, lastly, you could consider using a bleach-type solution to sanitize, but in most cases, removing the mold is the important aspect of it. It’s not just enough to kill the mold. You have to physically remove the mold, and that’s your main focus when you’re trying to get into this cleaning process.
When you use different cleaners or detergents, make sure you take a look at the product and read the label. It’ll give you an idea what the different concentrations are and how it can be used. That’s an important aspect when you get into the clean-out phase, trying to remove some of the mold and other water contaminants that came from the flood waters.
If you sanitize with a bleach solution, you can use a common spray bottle to do that, but it’s important to keep the surface wet for about five minutes or more. You can use systems like this to remove more efficient at doing that. Sometimes it helps to get into cracks and crevices better as well, and so those can be important tools to use in the sanitizing process.
The other note to make on sanitizing is that the bleach-type solutions tend to be more effective on nonporous surfaces like bathtubs, for example. Because of the porous nature of wood, it’s a semi-porous material, it tends to be less effective at killing microorganisms, so keep that in mind as you go through and sanitize in your home. Always read the label on that to get the appropriate concentration and use the product in a way that’s going to be effective.
