What is Surfex HD and why choose it?

Surfex HD from Bilt-Hamber is a response to the industry's need for a water-based degreaser that genuinely matches – and in many cases surpasses – solvent-based alternatives. Conventional solvent-based degreasers handle oil and grease but struggle with organic soiling and water-based deposits. Surfex HD tackles all of these contamination types within a single formula.

The product is caustic-free and emits no toxic vapours, making it safe to use in enclosed spaces such as engine bays and interiors. The extremely high concentration means a single bottle is sufficient for a large number of treatments, offering excellent economy for professional users.

Frequently Asked Questions (FAQ)

Does Bilt-Hamber Surfex HD work for interior cleaning and fabric upholstery?

Yes, Bilt-Hamber Surfex HD All-Purpose Cleaner works well for interior cleaning when diluted to a low concentration, for example 1:100 to 1:200. At these dilution ratios, Surfex HD is gentle on fabric upholstery, carpets and plastic trim, and effectively removes organic soiling and grease stains. Apply using a spray gun or soft brush, allow a short dwell time, and wipe away with a damp microfibre cloth. Avoid allowing the product to dry on the surface.

What dilution is recommended for engine bay cleaning with Bilt-Hamber Surfex HD?

For engine cleaning and engine bay degreasing, Bilt-Hamber Surfex HD All-Purpose Cleaner is recommended at a dilution of approximately 1:10, or undiluted for heavily baked-on grease and lubricants. Apply to a cool surface using a spray gun or brush, allow to dwell for a few minutes, and agitate with a stiff brush if required. Rinse thoroughly with a pressure washer. Surfex HD is Zero VOC and caustic-free, making it safe to use in engine bays without risk of damage to rubber and plastic components when used at the correct dilution.

What sets Bilt-Hamber Surfex HD apart from other APC products on the market?
