GroutGlow - Instantly covers stains for fresh, clean tiles

✔ Instantly hides stubborn grout stains: RenewalPro’s water-based pen covers orange, brown, and black stains with the first stroke, restoring the fresh look of your tiles—without heavy scrubbing or regrouting.

✔ Keeps grout fresh longer thanks to mold protection: The integrated anti-mold formula prevents mold from returning, keeping your grout especially in damp areas like kitchens and bathrooms clean and fresh for months.

✔ Safe and gentle for the whole family: This non-toxic, low-odor formula allows safe grout refreshment in homes with children and pets—even in small bathrooms—without worry about harsh chemicals or strong fumes.

Does the color match my existing grout?

With 12 available shades from bright white to coffee and dark gray, most users find a suitable option for typical grout colors. For custom grout, testing on an inconspicuous spot is recommended for perfect color matching.

How long does it last in damp shower areas?

With regular cleaning, clean grout can be expected for several months on walls and splashbacks. In heavily used showers, refreshing every few months with the pen keeps the grout looking fresh long-term.

Is it safe to use around children and pets?

Yes, the water-based, non-toxic, and low-odor formula contains no harsh bleaches or chemicals. It is safe for indoor use without hours of ventilation afterward.
