Your Grout Isn't Dirty. It's Been Slowly Turning Gray For Years.

One pen. One pass. Grout lines go from stained to bright white in under 10 minutes — no scrubbing, no chemicals, no contractor.

Most bathrooms need 3 pens, not 1.

A full floor plus shower walls runs 45–60 linear feet of grout — that's 3 pens. The 3-pack works out about 22% cheaper than buying them one at a time. Pick the 3-pack below to grab it.

Grout doesn't get dirty overnight. It fades slowly — a shade grayer every few months — until one day you're on your hands and knees with a toothbrush and nothing's changing. The grout isn't ruined. It's stained. And stained grout doesn't need to be replaced. It needs one coat of the right thing.

The JOSHKAS Grout Pen rolls a waterproof, mold-resistant colorant directly into the grout line. The surface absorbs it. It dries in minutes. The stain disappears under it — and stays gone through showers, mopping, and steam.

FAQ

Why is my grout grey even after I clean it?

Because it's not dirt sitting on top — it's stain that has soaked into the porous grout itself. Regular cleaning only lifts surface residue, so the grey underneath never comes out no matter how hard you scrub. The Grout Pen works differently: it recolors the grout from the surface down, covering the stain instead of trying to scrub it away.

Which color should I choose?

Available in White, Off White, Light Gray, Dark Gray, and Beige — the five most common grout colors in Canadian and American homes. Match your original grout tone before it stained, not what it looks like now.

Will it wash off in the shower?

No. The colorant absorbs into the grout surface and dries waterproof. Normal shower use, mopping, and steam won't remove it.

Do I need to prep the grout first?

A quick wipe to remove loose debris is enough. No deep cleaning required — that's the point.

How many pens do I need?

One pen covers roughly 15–20 linear feet of grout. A full bathroom floor plus shower walls typically takes 3 pens. The 3-pack gets the whole job done without running short mid-room.
