If you spot mold in your system, take immediate action to clean it thoroughly. Scrub the foundation filters with an abrasive sponge under cool running water for 2-4 minutes. After cleaning, prime and reinstall the filters. Run a batch of pre-treated water through the system to remove any remaining mold and prevent future growth.

For a deeper clean, add 16 drops of household bleach to each gallon of water used for cleaning. After washing with bleach, rinse thoroughly with warm water and mild dish soap.

White residue on your filters or in the lower chamber is likely due to ionized minerals present in hard or heavily mineralized water. While the BOROUX foundation filters do not remove minerals, wiping off the residue with a damp sponge should resolve the issue. This white material, often referred to as "white floaters," is harmless and simply indicates visible minerals that were previously invisible in the water.

To remove mineral build-up on the stainless steel spigot or the lower chamber, create a mixture of half white vinegar and half water. Scrub the affected areas with this solution and let them soak for at least 30 minutes to dissolve the residue effectively.
