Expert Notes

Hydro Boost is Dunking Biscuit's rinse-on sealant, a polymer based formula applied over a wet panel and rinsed away after around 60 seconds to leave a bonded layer of protection. The maker states the cross linked nano technology gives durability of up to 3 months, and the product can be mixed at a mid or higher strength depending on the level of protection wanted. It works with a mix bottle or a snow foam lance, making it a quick step to add to a maintenance wash rather than a full protection detail. It is safe on matte paint and vinyl wraps at a lower dilution, so it suits mixed fleets of finishes. Pair it with a two bucket wash and a clean microfibre drying towel.

Perfect For / Suitable Surfaces

  • Vehicle paintwork
  • Matte paintwork
  • Vinyl wraps
  • Maintenance washes
  • Wash and rinse routines
  • Home valeting
  • Mobile valeting

Caution: Work one panel at a time while it is still wet and rinse the product off after around 60 seconds to avoid it drying on the surface.

How To Use

Application

  1. Ensure the vehicle is clean and still wet from the wash stage.
  2. Mix 25ml of Hydro Boost with 475ml of water for a mid level of protection, or 50ml with 450ml for a higher level.
  3. Shake the solution and spray it onto one panel at a time while still wet.
  4. Alternatively, add 50 to 75ml of solution to a clean snow foam lance with 500ml of water and apply it to the car.
  5. Rinse the panel off after around 60 seconds.

Aftercare

  1. Do not let the solution dry on the panel before rinsing.
  2. Work through the panels in the same order you plan to apply the sealant.
  3. Store the bottle upright out of direct sunlight and away from frost.
  4. Rinse the mix bottle or foam lance after use to stop residue building up.

Top Tip: Work one panel at a time and rinse within about 60 seconds so the sealant does not dry unevenly.

The Brand

Dunking Biscuit

Dunking Biscuit, full name Dunking Biscuit Effortless Detailing, is a car care range that was made by Dunking Biscuit Ltd. On its own website the brand said it produced detailing products for car enthusiasts and detailing professionals, and that detailing is in its DNA, driving it to make products that are simple to use but highly effective. Its range ran from shampoos and snow foams to hybrid paint sealants and quick detailers, with accessories to help with application, removal and maintenance.

The Drivers HQ stocks Dunking Biscuit across car shampoos, snow foams, glass cleaners, wheel cleaners, quick detailers, tyre dressings, microfibre washes and spray air fresheners. Highlights include Aura Ceramic Quick Detailer, Blitz Wheel and Tyre Cleaner, Citrus Blast Bug and Grime Remover, Elixir Plastics and Trim Dressing and Dynamic Microfibre Wash Liquid, with some of them also available in 2500ml bottles or as samples. There is also the Show Wax 01 Cure Kit, the Rim Ticklers Wheel Woolies, The Dunking Hauler detailing bag and Air Fresh in Cherry Cola, Grape and Lemon.

Dunking Biscuit suits enthusiasts who want an easy to use range that still covers every stage of a proper wash. A typical routine starts with a pre-wash on bug splats and road grime, then a wheel and tyre clean before the contact wash with a shampoo and two buckets. After drying, a quick detailer or wax adds gloss and protection, while a trim dressing and glass cleaner finish the exterior. Washing your microfibres with a dedicated liquid helps keep them absorbent for the next detail.

From Pre-Wash to Show Wax

Citrus Blast Bug and Grime Remover is a pre-wash cleaner for stubborn dirt, grime and bug splats. Dunking Biscuit says its formula thickens once applied and clings to the paint like a gel to loosen road grime, salts and bug splats, and that it is designed to be safe on all surfaces, waxes and sealants. For the wheels, Blitz Wheel and Tyre Cleaner is non-acidic and non-caustic, and can be used anywhere from neat to a 10:1 dilution depending on how dirty the wheels are.

Aura Ceramic Quick Detailer is an SiO2 infused spray for paintwork, metal, glass and plastics. The brand says a simple spray and wipe gives 3 months of protection, and that Aura works as a maintenance topper over existing protection while removing dust, watermarks and fingerprints. Show Wax 01 is blended from a range of waxes including Carnauba T1 grade wax, and the brand describes it as easy on, easy off, with a show ready shine and a fresh lemon scent.

Aftercare is covered as well. Elixir Plastics and Trim Dressing is a gel that the brand says restores dull, faded trim with a deep waterproof shine and protection for up to 4 weeks, and Dynamic Microfibre Wash Liquid is a mild, concentrated wash made to keep microfibres absorbent, by hand or in the machine. The Dunking Hauler holds 35 litres of kit, with custom loops to keep bottles secure and mesh pockets on the outside.
