Bilt Hamber Auto-Wash is an exceptionally concentrated automotive shampoo designed to deliver effective, residue-free cleaning while helping protect exposed metal against corrosion. Its salt-free formula contains no added waxes, colourants, perfumes, or thickeners, leaving paintwork thoroughly clean and ready for drying, polishing, waxing, or sealing. With only 5mL required for up to 10 litres of water, Auto-Wash delivers up to 100 washes from a single 500mL bottle.

Key Benefits

• Extremely Concentrated: Just 5mL is required for up to 10 litres of wash water, providing outstanding value per wash.
• Anti-Corrosion Formula: Provides long-term corrosion protection for exposed steel, stone chips, seams, and vulnerable metal areas.
• Effective Cleaning: Powerful surfactants loosen and lift particulate contamination away from paintwork for safer removal.
• No Added Wax: Cleans without depositing waxes or gloss-enhancing additives that could interfere with later detailing stages.
• Salt-Free: Formulated without salts that may become trapped in vehicle seams and contribute to corrosion.
• Residue-Free Finish: Contains no colourants, perfumes, or unnecessary thickeners and rinses cleanly from the surface.
• Preparation Safe: Ideal before polishing, waxing, sealing, or other protective treatments.
• Suitable for Older Vehicles: Particularly beneficial for vehicles with stone chips, exposed steel, or ageing paintwork.
• Environmentally Considered: Highly concentrated formula means less chemical is required for each wash.

Why Auto-Wash Is Different

Many automotive shampoos contain waxes, fragrances, colourants, salts, and thickening agents that are not required for effective cleaning. Bilt Hamber Auto-Wash takes a more functional approach, using a highly concentrated surfactant system to remove contamination while leaving minimal residue behind.

Its anti-corrosion properties also make it particularly suitable for older vehicles and paintwork with stone chips or exposed areas of mild steel. This protection helps reduce the risk posed by corrosive elements becoming trapped within seams and other vulnerable areas.

Recommended Dilution

• Standard Wash: Add 5mL of Auto-Wash to up to 10 litres of warm water.
• Suggested Dilution: Approximately 1:2000.
• Estimated Washes: Up to 100 washes from 500mL

How to Use

1. Measure the Shampoo: Add approximately 5mL of Auto-Wash to an empty wash bucket.
2. Generate the Lather: Fill the bucket with up to 10 litres of warm, fast-flowing water.
3. Pre-Wash the Vehicle: Remove loose and heavy contamination with a suitable pre-wash before contact washing.
4. Wash Safely: Clean the vehicle from the top down using a premium wash mitt or wash pad.
5. Rinse Your Wash Media: Regularly clean the mitt or pad in a separate rinse bucket to remove trapped contamination.
6. Rinse Thoroughly: Remove the remaining shampoo with clean water.
7. Dry the Vehicle: Finish with a clean microfibre drying towel or vehicle dryer.

Important Information

Auto-Wash is designed primarily as a bucket shampoo rather than a pressure washer or snow foam product. For pressure washer pre-cleaning, use a dedicated product such as Bilt Hamber Auto-Foam or Touch-Less. Avoid washing hot panels or working in direct sunlight, and never allow the shampoo solution to dry on the surface.

PRO TIP: Auto-Wash is far more concentrated than most automotive shampoos, so using extra product is unnecessary. Measure approximately 5mL per 10-litre bucket to maintain its excellent rinsing performance and avoid product waste.
