You don’t have to use cleaning chemicals to whiten tile grout joints. Although you can find effective solutions on the market, there are some cheap organic ingredients that are perfect for this task.

Tile grout joints are filled with a paste that often wears out due to moisture, dust, and other substances that accumulate there. While it’s not noticeable at first, tile joints acquire a dark color due to mold growth.

The worst part of all is that the walls start looking unhygienic and the accumulation of these microorganisms increases the risk of allergies. Therefore, you should clean them at least once a week.
