Expert Notes

Car-Chem 1900:1 Shampoo is a highly concentrated maintenance shampoo for the contact stage of a hand wash. Car-Chem's guidance is approximately 15ml in a 25L bucket of warm water, agitated with a pressure washer, so only a small dose is needed each time. It is formulated with lubricants to help the wash mitt glide and reduce the risk of marring, while its long-lasting suds lift dirt away from the paint. For protected cars the key point is that Car-Chem states it will not strip existing wax and preserves sealants and ceramic coatings. We would pair it with a snow foam pre-wash, a two bucket setup with grit guards, a soft wash mitt and a plush microfibre drying towel.

Perfect For / Suitable Surfaces

  • Painted bodywork
  • Waxed paintwork
  • Sealant protected paint
  • Ceramic coated paint
  • Two bucket hand washes
  • Regular maintenance washes

Caution: Car-Chem classes the concentrate as causing skin irritation and serious eye damage, so wear gloves and eye protection when dosing the bucket.

How To Use

Application

  1. Rinse the vehicle with water to loosen and remove loose dirt.
  2. Pre-soak the car with a snow foam first, as Car-Chem recommends.
  3. Add approximately 15ml of shampoo to a 25L bucket of warm water.
  4. Agitate the water with a pressure washer jet to build the suds.
  5. Wash the paintwork with a dedicated wash mitt, working from the roof downwards.
  6. Rinse each section thoroughly with water before the suds can dry.

Aftercare

  1. Dry the vehicle with a clean microfibre drying towel.
  2. Rinse the wash mitt and buckets thoroughly after every wash.
  3. Machine wash microfibre mitts and towels separately, without fabric softener.
  4. Close the bottle tightly and store it upright away from frost and heat.
  5. Top up your wax or sealant when you notice its water behaviour fading.

Top Tip: Car-Chem recommends using de-ionised water throughout the whole washing process, from the first rinse to the last.

Frequently Asked Questions

What does 1900:1 mean on this shampoo?

It is the dilution ratio the shampoo is named after, so only a small dose is needed per bucket. Car-Chem's own guidance is approximately 15ml in a 25L bucket of warm water.

Will it strip my wax?

No. Car-Chem states that 1900:1 Shampoo will not strip existing layers of wax, so it can be used for regular washes between wax applications.

Can I use it on a ceramic coated car?

Yes. Car-Chem describes 1900:1 Shampoo as preserving the integrity of ceramic coatings as well as waxes and sealants, which makes it a maintenance shampoo for protected paint.

What sizes are available?

Car-Chem 1900:1 Shampoo is available in 500ml and 5L sizes.

How do I use it?

Rinse the car, add about 15ml to a 25L bucket of warm water, agitate with a pressure washer and wash with a dedicated wash mitt. Rinse thoroughly with water afterwards.

Should I pre-wash before using it?

Yes, Car-Chem recommends a snow foam pre-soak after the first rinse. Removing loose grit before the contact wash lowers the risk of marring.

What should I pair it with?

Pair it with a snow foam, a two bucket setup with grit guards, a soft wash mitt and a microfibre drying towel. Finish with a wax, sealant or quick detailer to suit your routine.

Where can I buy Car-Chem 1900:1 Shampoo?

It is available from The Drivers HQ with UK-wide delivery, and our walk-in store is in Ilkeston, Derbyshire.

HQ Suggests Tips & Insights

  1. Measure the dose instead of pouring by eye for consistent results.
  2. Rinse loose grit off before any mitt touches the paint.
  3. Snow foam heavily soiled cars before the contact wash.
  4. Keep separate buckets and mitts for wheels and paintwork.
  5. Wash from the roof down and leave the lower panels until last.
  6. Avoid washing in direct sun where suds can dry on the panel.
  7. Use de-ionised water throughout the wash, as Car-Chem advises.
  8. Order online with UK-wide delivery from The Drivers HQ.

The Brand

Car-Chem

Car-Chem is a car care manufacturer with an on-site laboratory, a dedicated research chemist and a production facility in Nottingham. The company says it has researched, developed and produced car care since 2010, and that its products are trusted by professionals and enthusiasts in over 40 countries. In 2024 it was acquired by Leading Solvent Supplies, a UK chemical group, and alongside its own Car-Chem range it develops and produces private label products for other businesses.

The Drivers HQ stocks Car-Chem across the whole wash and protection routine, with several products in 500ml and 5L sizes. For washing there is Pre Soak+ Snow Foam, Citrus Clean, Total Clean Traffic Film Remover, 1900:1 Shampoo and Clean Wheels. Protection comes from Sapphire Ceramic Wax, Connoisseur Carnauba Wax and Hydro Quick Detailer, with Prep Panel Wipe to ready the paint. Inside there is Interior Clean Coat, Hide Leather Cream and Refresh Odour Eliminator, and for glass, Pre Icer and Screen Wash Water Resistant.

Car-Chem suits enthusiasts who want to build a complete kit from one maker, and detailers who get through a lot of product, since the 5L sizes are handy for refilling smaller bottles. A typical routine starts with snow foam and a citrus pre-wash to loosen dirt before a careful contact wash with shampoo, then the wheels. Panel wipe removes oils before a ceramic or carnauba wax goes on, and a quick detailer keeps the finish topped up between washes. Glass and interior products finish the car inside and out.

Buy Car-Chem from The Drivers HQ with UK-wide delivery, or visit our walk-in store in Ilkeston, Derbyshire, where Click & Collect is free. Whether you are restocking a favourite shampoo in a larger size, trying a ceramic wax or putting together a winter glass kit with Pre Icer and screen wash, you can combine Car-Chem products with the rest of your detailing and car care essentials in a single order.

CARCHEM SAPPHIRE CERAMIC WAX - The Drivers HQ

From Snow Foam to Ceramic Wax

Car-Chem describes 1900:1 Shampoo as a highly concentrated shampoo that cuts through dirt, grime and road contaminants while preserving waxes, sealants and ceramic coatings, with lubricants that give a smooth glide and reduce the risk of swirls, scratches and marring. Before the contact wash, Pre Soak+ Snow Foam lifts dirt and grime from exterior surfaces without stripping sealant or wax, and Citrus Clean is a versatile cleaner for jobs inside and outside the car, diluted with water to suit the task.

Clean Wheels is an acid-based spray cleaner that the brand says is suitable for alloy, painted and plastic-trimmed wheels, lifting brake dust, grit and grease. When the paint is clean, Prep Panel Wipe removes oils and silicones to leave a streak-free surface ready for last stage protection.

For that protection, The Drivers HQ stocks Sapphire, an SiO2 based ceramic wax, and Connoisseur Carnauba Wax, which protects against contamination while adding to the natural gloss of the paint, with Hydro Quick Detailer adding a thin layer of hydrophobic sealant between washes. Pre Icer is a glass coating that helps stop ice settling on treated glass, Screen Wash Water Resistant is a screen wash additive that coats the windscreen with a hydrophobic barrier, Hide Leather Cream moisturises leather and Refresh Odour Eliminator targets bad smells at the source.
