Non-toxic ways to get rid of the mold

If you have mold in your home, you can get rid of it without using toxic chemicals. What is even better is the fact that you can use common household chemicals that you already have in your kitchen.

With the following solutions, you don’t have to spend a lot of money in order to get rid of your mold problem.

Vinegar

Vinegar is one of the most effective mold killers in the home. Studies have consistently found that it can kill up to 80% of mold species, which makes it pretty good at getting mold from surfaces.

To effectively use it, mix it in equal parts with water and then pour it in a spray bottle. Clean the mold-infested surface, vacuum it and then spray the mixture on the surface. Give it about 60 minutes to work and then rinse the surface.

Baking soda

All you need to get rid of a mold is just a spoonful of baking soda. Mix it with water in a spray bottle, shake it and then spray the resulting solution onto a cleaned-up mold-infected surface. You can use a soft brush to get rid of stubborn mold stains and after you are done, rinse and dry the surface.

Hydrogen peroxide

Homeowners have found great mold removal results from cleaning moldy surfaces with hydrogen peroxide that has a concentration of 3%. When it is sprayed on a surface and left for about 10 minutes, it actively kills mold. Therefore, applying a generous amount onto the mold surface, scrubbing the surface, and then letting it sit before wiping, is a great way of killing and removing mold.

Tea tree oil

Tea tree oil has a proven track record of killing fungi. Mold is no exception. When you mix a cup of water with a teaspoon of this essential oil, you will get a potent mold killer. Simply place the resulting solution in a spray bottle and then generously spray it onto the affected surface. When you leave it in place for about 2 hours and thereafter dry it out with a towel, you will have killed and removed any traces of mold.

How to remove mold on wood

Even though the exact steps recommended by manufacturers may vary slightly — some don’t even require rinsing or scrubbing –, the following are the general steps that you should follow in order to effectively remove mold on wood.

  1. Start by protecting your eyes, mouth, hands, nose, and skin from mold spores. This involves wearing long-sleeved clothing, putting on a pair of rubber gloves, wearing goggles, and a respiratory mask that covers both your nose and your mouth.
  2. The next step should be to vacuum the surface. A vacuum that is fitted with a good HEPA filter is usually recommended for this stage of the process. And after you are done vacuuming, place the moldy waste in a ziplock plastic bag and then throw it in a dumpster.
  3. With the surface free from any loose mold particles, it is now ready for the application of the mold-killing solution. If you are using a good mold control spray like RMR-86 Instant Mold and Mildew Stain Remover Spray, you don’t have to worry about mixing ratios or having to buy a spray bottle. The product comes with a mold-killing solution that is already in a spray bottle and all you have to do is to spray it on the surface.
  4. With the solution applied, scrub the surface with a soft brush in order to get rid of any mold stains. Spray some more of the solution and then give it time to work. This may take up to an hour, although following the manufacturer’s instructions is always advisable.
  5. After the surface dries, take a piece of clothing and then spray on it some of the mold-killing solutions. Use the cloth to wipe the surface clean. And then leave it to dry. You can use fans to help increase the rate at which the wood surface dries.

Note: For some commercial products, rinsing the surface after the initial application is necessary. Therefore, if you are using such a product, it is a step that you shouldn’t skip if you want great mold removal and cleaning results.
