A Note From Garage Therapy

We were incredibly happy with /ONE: Car Shampoo V1 as we felt it really elevated people’s perception of what a truly premium shampoo should be. Aside from the incredible slickness and balanced suds the formula gave, we feel its greatest attribute was the consistency in which it performed in cold and warmer environments that really set it apart from other shampoos of its type. A testament to its performance was seeing professionals replace their existing shampoos whether trade or more boutique offerings and use them as part of the services they offer their clients. This is a story that is constantly repeating itself.

/ONE: Car Shampoo V2 represents 9 months of development to squeeze out greater performance within our formula without ruining the balance version 1 offered. We have stripped out more water from the formulation to make it even more concentrated ml for ml. This means you can use almost 50% less product that you use before if not go further. I have used just 5ml to a bucket with 16-17 Litres of water and it still performed. That is extreme but you can safely use just 10ml!

Whilst also increasing the concentration it has amped up two important qualities, Cleaning power and Lubricity. I have said before that having a product too slick is counterproductive however as you can now use less product, you now have a greater ability to dial in the characteristic of lubricity to your preference…10ml is the sweet spot. From our testing, we have also observed that the cleaning power for a pH neutral shampoo is second to none. Our formula is dead on pH7 but it behaves like a higher pH, the cars look visibly cleaner than version 1. We demonstrated on the UKDA open day in front of many professionals, in direct sunlight, that the same performance in extreme temperatures has not been compromised. Finally, the price is not moving for the moment!


Garage Therapy /ONE: Car Shampoo is a premium pure pH neutral Car Shampoo that is the perfect daily maintenance shampoo that your car’s paint deserves. A luxurious blend of concentrated surfactants, emulsifiers, and lubricants will gently and effectively clean the paint whilst being safe to use on waxes, sealants, and coatings.

Garage Therapy /ONE: Car Shampoo high concentrate formulation provides high lubricity, high foaming, and free rinsing performance ensuring a clean residue-free finish.

What is the best dilution ratio?

​During the development and testing, we have seen great performance from using just 10-15ml of product. This shampoo is highly concentrated!

​The performance of all shampoos depends on multiple factors such as water hardness. Due to this we recommend using 20ml as the standard and experiment lower or more depending on your preference.

​​Why Garage Therapy /ONE: Car Shampoo and not another brand?

An ultra-premium quality shampoo with incredible cleaning power, suds, and lubricity. the main advantage is its ability to maintain a level of performance for the whole wash process without loss of foam and lubrication.

How To Use

  1. Shake well before use. Dilute 20ml for a moderately dirty car in a 4-5 gallon bucket. Use 30ml for a heavily soiled car for extra cleaning, suds, and lubrication.
  2. ​Pre-rinse the car to remove any loose dirt.
  3. Wash the car with a mitt starting from the top, working down to ensure the dirtiest parts of the car are washed last.
  4. Rinse thoroughly.

For Best Results

  1. ​Use the two bucket wash method, with a wash and a rinse bucket.
  2. ​Agitate the wash bucket with a hose sprayer to produce rich luxurious foam.
  3. ​Work one panel at a time working in straight lines.
  4. ​Garage Therapy /ONE Car Shampoo is high foaming and can be used through a foam lance to provide additional lubrication.
