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.

Performance Benefits

  • Designed for quick rinse-on protection
  • Bonds to paintwork after rinsing
  • Reduces maintenance wash effort
  • Suitable for mid or high strength use

Dunking Biscuit wash, decontamination and wheels

Pre-wash. Citrus Blast (also 2500ml) is a citrus pre-wash for bug splats and road grime that thickens to a gel once applied. It is safe on waxes and sealants, matte paint and vinyl wraps: spray it on, leave it three to four minutes without letting it dry, then rinse. Velvet (also 2500ml) is a thick, pH neutral snow foam that needs just 25ml in a 1 litre foam lance and lifts dirt in about five minutes; Velvet V2 is the slightly alkaline version, at 15 to 25ml a wash.

Shampoos. Feelin' Bubbly is a high foaming, pH neutral shampoo with anti-marring additives and a tutti frutti scent: 20 to 30ml in a 20 litre bucket, with a second bucket of clean water to rinse the mitt. It comes as a sample and in 2500ml. Feelin' x The Drivers HQ is our shared pH neutral shampoo, with up to 25 washes in a 500ml bottle. Forged (also 2500ml) is a low foaming, SiO2 infused shampoo that leaves a hydrophobic layer, so it tops up existing protection as you wash.

Decontamination. Melt (and sample) is a pH neutral iron fallout remover that clings as a gel, for all wheel types, metals and plastics; leave it no more than five minutes, wear gloves and keep it off vinyl wraps. Purge is a sprayable gel for tar and sticky residue, applied to a dry surface. The Fine Grade Clay Bar (200g) lifts tree sap, fallout and other bonded dirt, used with Loob, a water based clay lubricant.

Wheels and tyres. Blitz (also 2500ml) is a non-acidic, non-caustic wheel and tyre cleaner: neat for heavy dirt, 5:1 for medium and 10:1 for light. The Rim Ticklers are a long and a short synthetic wheel woolie for wheels, exhausts and door shuts. Glitz Creme (and sample) is a water based gel tyre dressing that does not sling: four pea-sized drops on an applicator, then 20 minutes before you drive.

Hydro Boost (and sample) is a polymer rinse sealant rated at up to three months: mix 25ml with 475ml of water, spray it onto the wet car a panel at a time and rinse after about a minute. Quartz (and sample) is a liquid creme hybrid wax sealant that the brand rates at up to nine months. The Show Wax 01 Cure Kit boxes a 100ml tin of lemon scented wax made with T1 grade carnauba, an applicator and two microfibre cloths. Gleam is an all in one polish that cleans, polishes and leaves wax protection for around two months. Immerse is a gloss enhancing detailer for show day finishing, and Elixir is a gel trim dressing that restores faded plastics with protection for up to four weeks.

Interior and glass. Spruce (and sample) is a water based interior detailer for plastics, vinyl, rubber and metal, leaving a non-sticky, anti-static satin finish and a rhubarb scent. Luxour (and sample) cleans, conditions and freshens leather from a 240ml foaming pump. Optik (and sample) cleans outside glass and leaves a water repellent layer, while Vision (and sample) is an ammonia free glass cleaner that leaves a film to resist fogging.

Care and kit. Dynamic (and sample) is a concentrated wash that keeps microfibre towels and pads absorbent. The Microfibre Wash Mitt has deep strands, a foam core and an elasticated cuff. The Mix Bottle is a 500ml trigger bottle with a label to note what is inside, and The Dunking Hauler is a 35 litre detailing bag, 50 x 25 x 28cm, with bottle loops, Velcro dividers and mesh pockets.
