When facing the challenge of mold removal, safety should be top of mind. To protect yourself and others from potential health risks, it is essential to wear protective equipment such as gloves, safety glasses, and a face mask.

Also, make sure the area is adequately ventilated by opening windows or using fans to reduce the spread of spores and promote the circulation of fresh air.

Finally, be aware of the cleaning products you use, as some may contain harsh chemicals.

Having the right cleaning supplies is key to successful mold removal. Gather a bristle brush, sponge, bucket, water, mild detergent, and a mold-specific cleaning solution.
