Rinse with water and repeat if necessary. Cleaning unsealed grout can be a hassle, but it doesn’t have to be. Unsealed grout is more porous and prone to staining and mildew growth, so regular cleaning is crucial. However, harsh chemicals and scrubbing can damage the grout, causing it to deteriorate.

Luckily, a simple mixture of water and white vinegar can effectively clean unsealed grout without causing any harm. This solution is both affordable and environmentally friendly. In this article, we will discuss how to clean unsealed grout step-by-step, as well as some tips for preventing stains and mildew growth.


Understanding The Need For Cleaning Unsealed Grout

Unsealed grout is a type of fill material used between tiles and it lacks added sealant. Such grout is easily penetrable to dirt, debris, and moisture. Hence, cleaning unsealed grout is a necessity to maintain the tiles’ longevity and keep the area hygienic.

Unsealed grout’s porous nature makes it a magnet for mildew and mold. A surface clean may give an illusion that the tile is sparkling clean. However, the mold and dirt could be lurking in the grout. It is important to clean every nook and cranny of the tile’s unsealed grout.

This helps prevent an overgrowth of substances that can have negative health consequences. Neglecting unsealed grout can cause discoloration, staining and it can also cause your tiles to loosen, and other issues.

Tips For Daily And Weekly Maintenance

Regular cleaning routines are essential for keeping unsealed grout clean. Use a mild cleaning agent and a soft-bristled brush to clean the grout daily. For weekly cleaning, use a stronger cleaning solution for a deeper clean, such as a mixture of vinegar and baking soda.

Avoid using harsh chemicals and abrasives as they can damage the grout. To prevent future buildup and damage, wipe up spills immediately and use a sealant on the grout every six months.
