I dislike it when most people tells you to just scrub something with bleach. There some beach apartment improvement blogs will tell you to take diluted bleach & scrub moldy drywall with it. But these people don’t realize that bleach is mostly water, so you’re going to feed the mold getting it so wet adore this. That’s why there are special products out there adore mold-killing paint & Concrobium that will destroy mold spores without saturating the part with so much water. But these are not the only things you need to avoid with bleach, as anything with metal is going to slowly corrode with repeat exposure. One of the most notable examples is the evaporator coil found inside a correct air conditioning. Since these components are known to harbor mold, many people are immediately driven to scrub them with a diluted bleach cleaner. Doing this will most likely destroy your air conditioning’s evaporator coil. The corrosion from the bleach will be immediate & the effects will render the coil inoperable. Basically it will no longer absorb heat & cool your indoor air. That’s why there is a special aerosol cleaning made specially for evaporator coils in air conditionings & dehumidifiers. The cleaner is sold at most hardware stores & will keep your air conditioning smelling superb if you treat it properly. Now that I have started using air conditioning evaporator coil cleaning spray, I no longer get odd odors coming from my air conditioning during times of peak indoor cooling. And if any of that grime has caused dust to stick to the coil, it will melt away with enough of the aerosol cleaner applied to the part that is dirty.
