How to Clean an Aquarium Heater

Follow these steps to safely and effectively clean your aquarium heater:

Step 1: Turn Off and Remove the Heater

• Safety First: Always unplug the heater and let it cool for at least 15-20 minutes before removing it from the tank to avoid burns or damage.

Step 2: Prepare a Cleaning Solution
