What cleaning method should be used for mold and mildew in containers?

The recommended cleaning method for mold and mildew in containers is the use of a hot high-pressure wash. This method is effective because the combination of high pressure and hot water can penetrate surfaces and effectively remove biological contaminants like mold and mildew, which can be difficult to eliminate through less vigorous cleaning methods. The hot temperature helps to kill spores and bacteria that may be present, further preventing regrowth.

Additionally, using a hot high-pressure wash allows for a thorough cleaning of not just the visible mold but also any hidden spores or roots that might be embedded within the container’s surfaces. It is a more comprehensive approach compared to other methods, such as scraping or spot cleaning, which may only address superficial areas without ensuring that all mold and mildew is fully eradicated. Power grinding/painting may not adequately resolve the underlying issue, and although scraping can remove visible contamination, it does not effectively sanitize or eliminate the source of the problem. Thus, the use of a hot high-pressure wash is the most effective method for treating mold and mildew in containers.
