  1. You can use water and vinegar to soak your air stones. Using this method will take out dirt especially calcium lime deposits that is as a result of your reservoir having heavy mineral composition.

  2. Use hydrogen peroxide to soak your air stones overnight. Once you’ve done this, go ahead and wash thoroughly. Then blow air through the air stone till it is totally dried.

  3. Another cleaning agent is the denture-cleaning tablets. They are a dilute type of sodium hypochlorite bleach and they are safer than liquid bleach. So, get some clean water and put your air stone inside, and put as many denture-cleaning tablets. Allow your air stone to soak all night and wash using clean water and blow some air through the stone. Then you allow them dry.

Benefits Of Cleaning Air Stone

How often should I clean your air stone?

Every month. Air stones need to be cleaned regularly because they collect dust, lint and moisture from the air. These particles can make your air feel unpleasant.

What's the easiest way to clean my air stone?

The easiest way to clean an air stone is to turn off the unit, take out the air stone and use a soft cloth to wipe it down. If the air stone is covered with dust, lint or moisture, simply wipe it down and allow it to dry. You can also use a damp cloth or sponge to clean the air stone. Just make sure that the water doesn’t drip onto the unit itself. If you don’t want to remove the air stone from your air conditioning system, you can also purchase an air stone cleaner that will help keep your air stone clean. These air stone cleaners come in different shapes and sizes and are designed to fit different types of air stones. Some of them even have cleaning attachments.

Can you use hot water?

The first thing that I do is give it a good wash with hot water. I do this by putting it into a sink full of hot water and swishing it around for a bit. Then I rinse it out. Next I put it into a dishwasher and run it through the washer. I have found that if I run the washer at high speed, which is about the highest setting, then the water doesn't get too hot. After the washing is done I wipe it off with a rag and then dry it with a paper towel. Once it's dried, I put a thin layer of silicone spray on it and let it sit there for about 15 minutes. Then I take a dry cloth and rub it down the outside of the stone. That seems to get all the dust off and make it look really good. The last thing I do is put it in my glass container and store it away for next time.

How long do air stones last?

Air-filled ball bearings are made of a rubber material that is compressed to create a tight seal. The compression of the air and the ball bearing creates a durable product. I've read that the plastic is very durable. My old set lasted me 8 years. I was using them daily. If you're using them daily for a few months, then they'll probably last.
