Car-Chem's 1900:1 Shampoo is an award-winning shampoo that cuts through dirt with ease. Despite this, it will not strip existing layers of wax. Specially formulated, the lubricants give a smooth feel as you wipe exterior surfaces clean, reducing marring, whilst long-lasting suds help to lift dirt particles safely away.

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.

Car Chem 1900:1 Shampoo (500ml and 5L) - The Drivers HQ

Car-Chem wash, wheels and preparation

Pre-wash. Pre Soak+ Snow Foam is a highly foaming, biodegradable pre-wash that gives a rich, stable foam at a very high dilution and lifts dirt and grime without stripping sealant or wax. Total Clean Traffic Film Remover is the stronger road film cleaner for traffic film, dead bugs and bird droppings on paint, wheels, glass and trim, diluted from 10:1 to 100:1 depending on the job.

Shampoo. 1900:1 Shampoo takes its name from its dilution ratio. Car-Chem calls it an award-winning formula that cuts through dirt, grime and road film while keeping waxes, sealants and ceramic coatings intact, with lubricants and long-lasting suds that help keep marring down.

Wheels and all-purpose. Clean Wheels is an acid-based spray cleaner for most alloy, chrome, painted and plastic-trimmed wheels, used neat on heavy soiling or diluted 3:1, then brushed and rinsed. Citrus Clean is an all purpose cleaner for almost anything inside and outside the car, from carpet stains to wheel arches.

Before protection. Prep Panel Wipe removes oils and silicones to leave a streak-free surface ready for last stage protection.

CARCHEM SAPPHIRE CERAMIC WAX - The Drivers HQ

Car-Chem waxes, detailers, glass and interior

Waxes. Sapphire Ceramic Wax is a 100g SiO2 based ceramic wax from Car-Chem's in-house technical team, blending SiO2 with carnauba, montan and bees waxes and natural fruit oils, for protection and water beading with a traditional hand application; avoid driving for 24 hours after. Connoisseur Carnauba Wax protects against contamination while adding to the paint's natural gloss, goes on wheels too, and hazes in 5 to 10 minutes before buffing.

Between washes. Hydro Quick Detailer adds gloss and a microscopically thin hydrophobic sealant layer through polymer technology, and also works as a spray sealant straight after washing.

Glass. Pre Icer is a glass coating that goes on a dry windscreen before a frost and stays on, to stop ice settling. Screen Wash Water Resistant is a concentrated screen wash additive, used at 10:1, that leaves a hydrophobic barrier so rain beads and runs off.

Interior. Interior Clean Coat cleans and dresses in one pass with an applemint scent and a satin finish. HIDE Leather Cream feeds and moisturises leather for a deep, rich satin finish, and Refresh targets the bacteria behind bad smells and leaves a fragrance that lasts for weeks.
