Grout Restoration Pen - Cover Stained Grout Lines in Minutes

Cover Years of Stained, Dingy Grout in About 10 Minutes

Tired of dull, brown-tinted grout that makes your whole bathroom look old no matter how much you scrub? This water-based grout pen paints directly over stained, mould-spotted grout lines so your tile looks freshly installed without tearing anything out or hiring a contractor.

Stop Scrubbing Grout That Will Never Come Clean Again

Grout is porous. Once soap scum, oil, and mould soak into the surface, no amount of bleach or scrubbing will pull them back out. You can spend an hour on your knees with a toothbrush — and that orange-brown stain still wins.

➤ Covers Set-In Stains on the First Pass: Drag the tip over orange, brown, or black-stained grout and watch it vanish under a clean, bright line you'll actually want to look at.

➤ Built-In Anti-Mould Agents Slow Regrowth: The water-based formula contains anti-mould additives that help keep mould from settling back into the lines you just refreshed.

➤ Low-odour and non-toxic — safe for the whole house: No bleach fumes, no harsh solvents. Safe to use in a small bathroom with the door closed, even around children and pets.

Water-Based Colour Ink That Bonds to Porous Grout and Stays Put

The chisel tip lays down a thin, opaque pigment that soaks into the porous top layer of your grout and dries quickly, locking in a clean colour the same way a paint pen seals over scuffed metal. Once dry, the finish resists water, so everyday showers, splashes, and regular cleaning won't wash it away.

It won't peel or flake like cheap sealants can. With regular cleaning and decent airflow, refreshed lines keep their look for months — and when heavy-traffic spots eventually wear down, you can touch them up in seconds with the same pen.

Why DIYers Reach for This Pen Instead of Re-grouting

Homeowners who were quoted £400+ to re-grout a single shower are finding a single pen gets the visible job done in an afternoon. They're sharing before-and-afters of showers, kitchen backsplashes, and floor tile that look freshly retiled — without a single power tool involved.
