For years, you’ve been told to “scrub harder.” It’s a lie.
Grout is a porous sponge — scrubbing only lightens the top layer, so stains always return. The stain isn’t on it; it’s in it.
Grout Renew™ changes the game. It lays a thin sealed layer over the surface, locking old stains away and blocking new ones.
The only way to win is to create a new, impenetrable surface.
That’s what our Micro-Seal Technology does — a thin, stain-proof layer that grout scrubbing can never achieve.
Trusted by over 4,000 UK homeowners.
You can't clean a stained sponge. You have to cover it.
Our pen doesn't use thin, watery paint. It applies a proprietary Elastomer Sealant through a precision valve tip.
This sealant molecularly bonds with the old grout to create a new, waterproof, perfectly white surface.
You're not just 'cleaning'. You're restoring the barrier, permanently.
Three simple steps to make your grout look brand new — no scrubbing required.
Quickly wipe away surface dust — a clean base makes the sealant bond perfectly.
Remove the cap and press the tip 30× until the sealant begins to feed smoothly.
Simply trace the grout lines. In minutes, they're sealed, bright, and like new.
Real homes. Real transformations.
Surface scrubbing and harsh chemicals can't fix a stain that's inside the grout.
They only offer temporary results and wasted effort.
The Grout Renew Pen doesn't clean the old surface—it creates a new, perfect, non-porous one.
It's a permanent solution, not a temporary clean.

Walls & splashbacks: 6–12 months; floors & heavy-use showers: 3–6 months.
Touch-ups take minutes and keep it looking like new.
Once cured, Grout Renew™ bonds to the grout and won’t peel or wash away under normal cleaning.
For best results, allow 24 hours before heavy scrubbing or standing water.
Everything. Most cheap "grout pens" you see on Amazon or in discount shops use a thin, watery, paint-like formula. It looks okay for a week, then it cracks, flakes, or washes away.
Ours uses a micro-seal formula that repels dirt and moisture for years.
Our Grout Renew Pen uses a proprietary Antimicrobial Elastomer Sealant.
It's a thick, durable, and permanent formula that creates a new, non-porous surface over your old grout, locking out grime for good.
It's the difference between painting over a damp wall and properly sealing it—one is a temporary fix, the other is a permanent solution.
No problem at all! That's the beauty of our formula. If you get some on the non-porous tile surface, simply let it dry for a minute and then wipe it away with a damp cloth or scrape it off with a fingernail.
It's designed to bond strongly to porous grout, but not to the smooth, sealed surface of the tile itself, making cleanup foolproof.
Cleaning can’t reach deep-set stains, so they return fast.
Re-grouting costs £500–£1,000+ and is messy.
Grout Renew™ recolors and seals in one step—without the cost, dust, or hassle.
Treat mould and let dry fully before applying.
If grout is crumbling/loose, repair first—Grout Renew™ seals the surface; it isn’t a structural fix.
Yes—just a light clean to remove loose dirt and soap scum.
No need for hours of scrubbing—Grout Renew™ bonds best to a clean, dry surface.
Easily covers a typical room. Each Grout Renew™ pen contains enough advanced formula to restore up to 40 meters (about 130 feet) of grout lines.
For most homes, that's more than enough for a large kitchen or two standard bathrooms. This is why our "Buy 3, Get 3" bundle is the most popular choice for a full home makeover.
Absolutely. Your family's safety is paramount. The formula is water-based, non-toxic, and free of harsh chemicals and fumes, making it safe to use indoors.
Once the formula is dry, it is completely inert and poses no risk to children or pets who may come in contact with the floor.
It dries surprisingly fast. The formula will be touch-dry in as little as 30 minutes, depending on room ventilation and humidity.
For maximum durability and water resistance, we recommend allowing it to fully cure for 24 hours before exposing it to heavy water contact or cleaning.
Our brilliant white formula is designed to work on any existing grout colour—white, grey, beige, or anything in between.
It's formulated for maximum opacity to completely cover the old, stained grout beneath it.
Currently, we only offer Brilliant White as it's the most requested colour for creating that fresh, "like-new" look our customers love.
I’m Fiona — a mum from Leeds who got properly fed up spending every weekend scrubbing grout that never looked clean.
After trying every spray, bleach, and “miracle” hack under the sun, I learned the truth — grout isn’t dirty, it’s porous. The stains live inside it.
So I worked with local formulators and created Grout Renew™ — a simple pen that recolours and seals each line in one smooth stroke. No harsh smells. No endless scrubbing. Just that deeply satisfying “brand-new again” feeling.
Since then, over 4,000 UK homes have had that same little “wow” moment.
Give it a go — if your grout doesn’t stay bright for 6–12 months, we’ll buy it back.
