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.
