1. In a large bucket, combine the water and baking soda.
2. Let it dissolve, and little by little, start adding the white vinegar.
3. Next, add the hydrogen peroxide and keep stirring until everything is well integrated. At this time, you can add the tea tree oil if you’re using. There might be a little foam as a result of the reaction between the vinegar and baking soda, but this is normal and will dissolve with time.
4. Once the foam settles, add the mixture to a spray bottle so that it can be easily utilized (you might need a couple spray bottles to fill up, but it’ll last you a long time!).
5. Spray the mixture onto the mold and mildew and let sit for 20-30 minutes. Then, take a scrubby brush and start putting in some elbow grease. Once finished, rinse with water.
