Removing Mold Stains

Removing mold stains from basements and other porous surfaces can be a headache. Not only does mold smell and deface the surfaces of your basement it can also be a health problem. When removing mold stains remember to take all of the proper precautions.

Remove Mold Stains

Removing mold stains can be difficult depending on the type of mold and where the mold sits. Most damp places, such as basements, suffer from mold stains. Moist damp porous surfaces are great breading grounds for the microscopic fungi because it allows moisture to be trapped inside the material for an extended length of time before drying.

Mold can be found on the surface of porous materials, but you can have a more serious problem than you might think. There are some occasions where a small mold problem can quickly turn into a mold problem only professionals should handle.

For the most part you yourself can clean away the mold on the surfaces of your basement, but if you find black mold or the mold has found its way into the basement walls you may need to seek the help of a professional.

Mold is an eyesore, but it can also be a serious health risk. Most people do not even realize they are breathing in the microscopic spores that are released by the mold in the home. If the mold has gotten into the duct work, you could be causing your family harm by not seeking professional help.

The steps for removing mold are below.

Removing Mold Stains from Basements

What you will need:

  • A respirator
  • Safety goggles
  • Gloves
  • A razor knife
  • Spray bottle filled with water
  • Bleach
  • Clean water
  • Bucket
  • Mop or hardy sponge
  • Old large bath towel
  • A fan

Remember to take all of the necessary safety precautions before beginning a project like removing mold stains from your basement. Sometimes it may seem silly to wear certain personal protective equipment, but when removing mold stains you should make sure you where the suggested safety equipment.

  1. To begin mold removal you need to ensure that you put your respirator (or surgical mask), Safety goggles, and gloves on properly.
  2. Next, enter the basements and inspect the areas and materials you know can grow mold or is obviously growing mold. Begin by looking at any porous surfaces such as wood, sheet rock, paneling, wall hangings, etc... Next you will want to look at any other sign there could be mold such as a place where the paint is peeling away, there is a soft spot noticeable, there are water stains, moldy smells, etc..
  3. If you have sheet rock in your basement that has mold stains on the surface you should check behind the sheet rock to ensure the mold has not spread behind the walls. You can do this by taking a razor knife and cutting out a 12 by 12 inch square from the sheetrock. This size whole should allow you to inspect the inside of the wall. If there is no obvious mold you can proceed with the remaining steps to removing mold stains from your basement. 
  4. Now that you know what surfaces you need to clean and that you do not need any professional help you can begin the process of removing the mold stains.
  5. Begin by opening all of the ventilation in the basement. This means all windows and doors should be open. This will help dry out the basement and air out some of the musty smell that most basements have.
  6. Now you will need to dispose of any wall hangings or window treatments that might contain mold. You can try to clean them or you can replace them.
  7. Next, you should use the spray bottle filled with water to spray the moldy areas with a fine mist of water. This is done to try and keep the dust down when cleaning. If you have concrete walls you should use a soft brush to wipe away any dust or dirt on the walls.
  8. Mix a solution of 1 part bleach and 2 parts water in a large bucket. Try not to make the solution too strong because too much bleach can hurt your skin or make you feel light headed.
  9. Use a disposable, yet durable rag, sponge, or mop to wash the moldy areas. Make sure you do not use too much of the solution while cleaning. You do not want to soak the porous materials with too much water. This can cause more mold to grow rather than cleaning the mold that exists. Allow the bleach solution to sit for about 20 minutes.
  10. You should now rinse the walls with clean water. Again do not use too much water as this will do more harm than good. Directly after you will need to dry the area with an old bath towel.
  11. Finally, you should place your fan in the basement. Try and use the fans that pull the outside air into the basement. This should aid you in drying the basement thoroughly. Moisture is bad to have because it allows mold to return on the surfaces that you have just cleaned. 

If you have followed the directions properly you should be rid of your mold stains. If the stains remain you can repeat the steps for removing mold stains from basements. Remember if the mold is in the walls or it is a black mold you should seek the help of professionals before trying to take on the project yourself.
