CarLab PRO Pre-Rinse is a highly concentrated pre-wash formulated to maximally saturate the paint surface and effectively dissolve road film and heavy traffic contamination before the main wash begins. The product is designed to work within two separate systems: as a conventional pre-wash with pressure rinsing, or as dedicated support in a rinseless workflow alongside CarLab POLIWASH.

The formula works considerably more effectively than a standard shampoo spray and is 100% compatible with polymer technology. It creates a lubricating layer between dirt and paintwork that drastically reduces the risk of micro-scratches (swirls) during the wash process.

The concentrate is diluted at a ratio of 1:30, delivering a high yield per litre of product and making it cost-effective for professional use. See more CarLab products for car care in our range.

What is CarLab PRO Pre-Rinse and why choose it?

CarLab PRO Pre-Rinse is a professional pre-wash in concentrate form that dissolves and softens contamination before contact washing or rinseless washing is carried out. By applying the product to a dry surface and allowing it to dwell for 1–3 minutes, the bond between dirt and paintwork is broken down, minimising the risk of scratches during subsequent mechanical work.

What sets CarLab PRO Pre-Rinse apart from a standard shampoo spray is its dual functionality: the product works equally well with a pressure washer as without access to running water. In the rinseless variant, the pressure rinse is replaced by a generous spray layer of POLIWASH solution, making it possible to wash the vehicle safely even in a garage or on car parks without a water connection.

Where is this product suitable?

• Detailing studios and reconditioning workshops with pressure washing equipment
• Mobile detailers working without a fixed water supply
• Garage use and washing in residential areas (rinseless method)

Frequently Asked Questions (FAQ)

Does CarLab PRO Pre-Rinse work without access to a pressure washer?

Yes. CarLab PRO Pre-Rinse is designed to work within two separate workflows. In the rinseless variant, the pre-wash is applied to a dry surface and left to dwell for 1–3 minutes. It is then removed with a generous layer of CarLab POLIWASH solution from a hand spray bottle, after which the rinseless wash is carried out using a bucket and microfibre towels. The method is safe for the paintwork and requires no water connection.

What dilution ratio and volume does CarLab PRO Pre-Rinse come in?

CarLab PRO Pre-Rinse is supplied in a 5-litre container and is diluted at a ratio of 1:30, which equates to approximately 32 ml of concentrate per litre of water. From a 5-litre container, up to 155 litres of ready-to-use working solution can be obtained, making the product cost-effective for high-volume professional use.

What sets CarLab PRO Pre-Rinse apart from a standard shampoo spray used as a pre-wash?

CarLab PRO Pre-Rinse is a dedicated pre-wash formula and not a diluted shampoo. The formula is optimised to maximally saturate and dissolve road film and heavy contamination before contact washing begins, and creates a lubricating layer that protects the paintwork against micro-scratches (swirls). In addition, CarLab PRO Pre-Rinse is 100% compatible with polymer technology and does not damage applied Ceramic Coating or Sealant layers.
