Bilt Hamber surfex-HD


We Say

Bilt Hamber surfex-HD is a highly concentrated multi-purpose cleaner, and is an unbeatable choice for tackling neglected wheel arches, engine bays and undercarriage areas. It also excels at stripping previously applied sealants and waxes, and at general exterior cleaning duties when used at higher dilution rates. However, its concentrated nature must not be taken lightly, and care should always be taken to use an appropriate dilution strength for the task in hand, and to avoid letting it dry out fully before it's rinsed off, otherwise permanent stains may occur. In short, as long as it's used with care and at the recommended dilution ratios, Bilt Hamber surfex-HD is a brilliant value for money intensive cleaning product, and one that we happily recommend to home enthusiasts and professional detailers alike. Since testing it, it's quickly become our go to product for all intensive cleaning tasks!

Bilt Hamber surfex-HD is an environmentally-friendly water-based all purpose cleaner that provides a level of cleaning power equivalent to that of toxic solvent-based formulations, yet, unlike many such products, it is equally as effective on organic- and water-deposited grime as it is on grease and oil. Comprising an advanced blend of cutting-edge biodegradable surfactants, Bilt Hamber surfex-HD is non-toxic, pleasant to use and environmentally-friendly. Notwithstanding this, it is fast-acting and extremely potent, and very economical too; it can be diluted up to 100:1 (water:product) for light cleaning duties, or used neat for tackling thick grease and grime. Bilt Hamber surfex-HD is safe for use on virtually all automotive surfaces, but you should always spot-test it before use.

How To Use

Bilt Hamber surfex-HD is a highly concentrated multi-purpose cleaner, and should almost always be diluted to an appropriate strength before use. For general exterior cleaning duties (i.e. routine deep cleaning of trims, tyres and shuts) it should be diluted 10:1 (water:product), while for more intensive degreasing duties (i.e. periodic deep cleaning of wheel arches, the engine bay and undercarriage areas) it should be diluted 5:1 (water:product). In extreme cases (e.g. oil spills, engine rebuilds, etc.) it may be used neat, although care should be exercised and spot-testing performed. In all cases, an appropriately diluted solution should be sprayed directly on to the surfaces to be cleaned (which must be cool) and then agitated thoroughly with suitable detailing brushes before being rinsed off. Never allow Bilt Hamber surfex-HD to dry out fully before it is rinsed off, otherwise permanent staining may occur.
