Expert Notes

Car-Chem Pre Soak+ Snow Foam is a highly foaming pre-wash agent that Car-Chem describes as Pre Soak with a bit more bite. Mixed at 100 to 150ml in a 1L foam lance and topped up with deionised water, it produces a rich, stable foam that lifts dirt and grime from exterior surfaces without stripping sealant or wax protection, and the formula is biodegradable. We use it as the first stage of a safe wash: pre-rinse, foam from top to bottom, leave it for 5 minutes without letting it dry, then rinse thoroughly with a pressure washer before a two bucket contact wash. Dilute it further for lighter soiling. Pair it with a quality foam lance, a gentle shampoo and a plush wash mitt.

Perfect For / Suitable Surfaces

  • Painted bodywork
  • Waxed or sealed paint
  • Exterior glass
  • Plastic trim
  • Wheels and tyres
  • Lower sills
  • Wheel arches

Caution: Do not let the foam dry on the panels, so avoid direct sun and hot bodywork. Rinse fully before starting a contact wash.

  4. Allow it to dwell for 5 minutes without letting it dry.
  5. Rinse thoroughly with a pressure washer.
  6. Move on to a two bucket contact wash.

Aftercare

  1. Flush the foam lance through with clean water after use.
  2. Check the lance filter and nozzle if the foam becomes thin.
  3. For lightly soiled cars, dilute Pre Soak+ further as Car-Chem suggests.
  4. Rinse any dried foam marks from glass and mirrors before drying.
  5. Store the bottle sealed, upright and away from frost.

Frequently Asked Questions

What dilution does Pre Soak+ use?

Car-Chem recommends 100 to 150ml of Pre Soak+ in a 1L foam lance, topped up with 900ml of deionised water. For less aggressive cleaning you can dilute it further.

How long should I leave it on?

Leave Pre Soak+ to dwell for 5 minutes, then rinse thoroughly with a pressure washer. Do not let the foam dry on the paint, especially in warm weather.

Will it strip my wax or sealant?

No, Car-Chem says the formula lifts dirt and grime without stripping sealant or wax protection.

Is it biodegradable?

Yes, Car-Chem describes Pre Soak+ as a biodegradable formula.

How is it different from Pre Soak?

Car-Chem describes Pre Soak+ as Pre Soak with a bit more bite. It is a specially formulated, highly foaming pre-wash agent that produces a rich, stable foam.

Do I need a pressure washer?

Yes, Pre Soak+ is applied through a foam lance on a pressure washer and rinsed off with the pressure washer. A lance with an adjustable nozzle helps you control foam thickness.

Do I still need to hand wash afterwards?

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.

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.
