Bilt Hamber Car Care: Where to Start (Essential Products Guide)
Bilt Hamber is a UK, chemical-led detailing brand known for effective, non-caustic formulas and very high dilution ratios. For a first kit, start with Auto-Foam (alkaline touchless pre-wash, 1:20–1:100), Auto-Wash (pH-neutral shampoo, 1:2000) for the contact wash, and Korrosol (neutral fallout remover, ready-to-use) for decontamination.

Recommended starter picks
- Auto-Foam — Bilt Hamber's signature pre-wash; alkaline (pH 13) yet marketed as non-caustic, it lifts road film in a touchless pass and the maker states it is safe on surfaces treated with waxes and polishes. Foam it 1:20–1:100 and rinse before contact.
- Surfex-HD — the go-to all-purpose cleaner and degreaser (pH 13, 1:10–1:20); winner of the Auto Express 2018 award, it handles wheels, engine bays, tyres, fabric and heavy exterior grime from one bottle. Being strongly alkaline, it is a cleaner — not a coating-safe shampoo.
- Korrosol — a neutral (pH 6) iron/fallout remover that colour-shifts as it dissolves bonded metallic contamination; sprayed ready-to-use on cool paint, it is the safe decontamination step before claying.
- Auto-Wash — the everyday contact-wash shampoo; pH-neutral (7) so it won't strip wax or coatings, and extraordinarily concentrated at 1:2000, so one bottle lasts a very long time.
- Auto-Wheel — a pH-neutral (6) non-acid wheel cleaner and fallout remover, ready-to-use and safe across common wheel finishes.
- Auto-Clay — a water-lubricated decontamination clay for removing bonded contamination after chemical fallout removal, ready-to-use with plain water.
- Cleanser-Polish — a mild pre-wax cleanser that lightly cleans and boosts gloss to prep paint before applying a wax or sealant.
- Auto-Balm — a wipe-on paste protection (LSP) for a durable, low-effort finish once the paint is clean and prepped.
How to choose
Build outward from the wash process, not the badge: a pre-wash foam plus a neutral shampoo cover most routine washing, so start with Auto-Foam and Auto-Wash. Mind the pH — Auto-Foam and Surfex-HD are strongly alkaline (pH 13): rinse them fully and never let them dry on a hot panel, and treat Surfex as a heavy-duty cleaner rather than a coating-safe shampoo. The neutral products (Korrosol, Auto-Wheel, Auto-Wash) are the LSP-friendly ones. Much of Bilt Hamber's appeal is concentration: a 1:2000 shampoo and high-ratio foam mean a very low cost per wash.
FAQ
Which Bilt Hamber product should I buy first?
A neutral shampoo. Auto-Wash (pH 7, 1:2000) is the safest, most-used product in the range and won't strip existing wax or coating — add Auto-Foam as a pre-wash next.
Is Bilt Hamber Auto-Foam safe on wax and ceramic coatings?
The manufacturer states Auto-Foam is non-caustic and safe on surfaces treated with waxes and polishes, despite its high pH. Use it as a rinse-off pre-wash at 1:20–1:100 and don't let it dry on hot paint.
Why are Bilt Hamber products so concentrated?
Bilt Hamber formulates for high dilution — Auto-Wash runs at 1:2000 and Auto-Foam at 1:20–1:100 — which detailers cite as strong value, since one bottle covers many washes.
