Can bleach be used to clean aluminum gutters?

It's not recommended to use bleach to clean aluminum gutters, as it can cause discoloration and damage to the metal over time. Instead, a mixture of mild soap and water or a specialized gutter cleaner is safer and more effective. If you do choose to use bleach, it should be highly diluted and rinsed thoroughly to minimize potential harm. Always follow up with a thorough rinse to prevent any residue buildup.
