Either of the two, make sure that you will apply the mixture thoroughly and generously. Let it sit for a couple of minutes to ensure effectiveness. 

Step #4. Scrub the mildewed area in a circular motion. Remember to not ruin your mattress by brushing too hard. 

Step #5. Clean the area again using an ample amount of warm water. This step aims to rinse the alcohol solution and the particles of mildew.

You can also use a spray bottle in doing this so that you can control the amount of disinfectant. Too much will also be dangerous to your health. 

Step #7. Dry the mattress and keep it that way at all times. Do not use it right after you remove the mildew. 

Hang it in a place where it can get sunlight. You can also do this after using it at night, instead of just putting it in a corner.
