Finally, grout that looks new again
You've scrubbed. You've bleached. You've tried every cleaning hack on Pinterest.
And your grout still looks dirty.
It's not your fault. Stains sink deep into grout. No amount of scrubbing brings back that fresh, clean look. But Groutglow™ does something different. Its water-based formula absorbs directly into grout lines, covering years of discoloration in a single stroke.
Your kitchen. Your bathroom. Your entryway. They all look new again—without regrouting, without contractors, without the hassle.
One of our fastest-selling home repair tools this season
✓ Stop scrubbing, start covering
Scrubbing doesn't fix stained grout. It just exhausts you. Groutfix™ covers discoloration in one smooth stroke—no bleach, no brushes, no wasted weekends.
✓ Water-based formula, zero harsh fumes
Safe around kids and pets. The non-toxic ink dries fast, stays put, and won't fill your bathroom with chemical smells. Just color and go.
✓ 12 colors to match any tile
White, gray, beige, brown, gold, black—we've got them all. Pick the exact shade that matches your grout, or go darker for a fresh new look.
✓ Includes replacement tips
Every pen comes with an extra nib. When the first one wears down, swap it out and keep going. No interruptions. No wasted product.

Can I use this in the shower?
Yes. The waterproof formula is designed for wet areas like showers, bathroom floors, and kitchen backsplashes.
How long does one pen last?
One pen typically covers 50-80 feet of standard grout lines. For large projects, consider ordering multiple pens.
Will this work on rough or textured grout?
Yes, but textured grout may require a second coat for even coverage. The replacement nib helps with rougher surfaces.
How long until it dries?
The formula dries in about 30 minutes. Avoid water contact for 24 hours for best results.
- Step 1: Clean and dry the grout lines thoroughly before applying.
- Step 2: Shake the pen well, then press the nib down several times to start ink flow.
- Step 3: Apply in smooth, even strokes along the grout line. Wipe any excess off tile immediately.
- Step 4: Allow to dry for 30 minutes. Apply a second coat if needed for deeper coverage.
