THE TRUTH ABOUT DECON SHAMPOO 👀

I think Decon Shampoo is one of the most misunderstood products in car detailing.

When I first started using Garage Therapy's /ZERO: Decon Shampoo, I didn't fully understand where it fitted into my detailing routine.

And looking at some of the videos I've seen recently, I think that same confusion still exists today.

It's not necessarily that people are using it wrong. It's that they might not be getting the most out of what this product can actually do.

So in this video, I'm sharing what I've learned, how I use Decon Shampoo, and where I believe it really belongs in your detailing process.

Are you getting the most out of your Decon Shampoo?

Let me know how YOU use it! 👇

QFR • UNSEEN FOOTAGE 🎬

Back in April 2026, I picked up this bottle with no idea what to expect. Wearing my Meta glasses, I captured my first reaction as it happened.

What I saw—and what I felt—was incredible. What I didn’t realise at the time was that I was testing the final version of Garage Therapy QFR.

Since then, I’ve spent months using it in my detailing business. That first impression now has plenty of real experience behind it.

For my first longer video here on Instagram, I’m sharing the full 7 minutes and 30 seconds so you can see that first test for yourselves.

The bottle says Quick Detailer, but it’s QFR inside. 👀

Enjoy this look behind the scenes. I hope it gives you a better understanding of the work that goes into Garage Therapy’s products—and why I was so impressed from that very first use.

Have you tried QFR yet? I’d love to hear your thoughts. 👇

10 years of neglect. One day. £250 to bring it back.

This BMW 635CSi arrived covered in ingrained dirt, with faded, chalky single-stage paint hiding its rich red finish.

Garage Therapy /ZERO: Decon Shampoo tackled the build-up before the FLEX rotary got to work on the oxidation.

This wasn’t about making every defect disappear. It was about preserving a classic and giving it another chance to shine.

Would you have taken on the challenge?

💧 Garage Therapy QFR — Quick Finish Restorer

I’ve been testing QFR, Garage Therapy’s new Quick Finish Restorer, and this is a really interesting product.

QFR is designed for those annoying light water spots and mineral deposits that can be left behind after washing or from hard water. Its mildly acidic, demineralising formula helps deal with those deposits while restoring that clean, slick finish to the paintwork.

But what makes QFR interesting is that it doesn’t just clean.

Once applied, it leaves behind around 2–3 weeks of protection, adding gloss, hydrophobic behaviour and helping improve the surface’s self-cleaning ability.

It can also be used on glass, making it a really useful finishing product after the wash.

One important point though — QFR isn’t a dedicated heavy water-spot remover. If you’ve got severe or etched-in water spotting, you’ll need something more aggressive. This is about dealing with lighter mineral contamination while restoring and topping up the finish at the same time.

For me, it sits in a really interesting place in the Garage Therapy range — somewhere between a finishing product, a light demineraliser and a short-term protection topper.

Definitely one I’ll be using more of. 👌

Right, let’s talk QFR.

That’s Quick Finish Restorer — the new addition to Garage Therapy’s /TWO: range.

If you’re thinking “another quick detailer?”, there’s a bit more to this one. It’s closer to a treatment product, so this video gets into what it does and why Garage Therapy created it.

Give it a watch and let me know what you reckon. What would you want to see me put it through? 👇
