Full Description

Alchemy Grime is a concentrated citrus pre-wash that can be used across the entire car exterior and even be used as an APC on the interior.

Grime is tough on all the nasty things you don't want on your car, like grime, salt, bug splatter, tree sap and grease, but won't strip wax or sealants.

As Grime is a concentrated formula, you can dilute to suit your needs, for heavy soiling 10:1; medium soiling 50:1; light soiling 100:1.

Expert Notes

Alchemy Grime is a concentrated citrus pre-wash for the stage before your mitt touches the paint. Alchemy rates it as tough on grime, salt, bug splatter, tree sap and grease, while leaving wax and sealants in place, so it suits protected cars as well as unprotected paint. Dilution follows the job: 10:1 for heavy soiling, 50:1 for medium and 100:1 for light. It runs through a spray bottle or a foam lance, though it will not foam, and is left to dwell then rinsed with clean water. It also doubles as an interior all purpose cleaner. Pair it with a pH neutral shampoo, a two bucket wash and microfibre drying towels.

Perfect For / Suitable Surfaces

  • Exterior paintwork
  • Lower panels and sills
  • Front ends with bug splatter
  • Areas with tree sap
  • Road salt and grime build-up
  • Waxed or sealed paintwork
  • Interior cleaning as an APC

Caution: Do not let the diluted solution dry on the surface: work in the shade on cool panels and rinse thoroughly. Test interior dilutions on a hidden area first.

  3. Spray onto the exterior, starting with the lower panels where dirt is heaviest.
  4. Leave to dwell, but do not let the solution dry on the surface.
  5. Rinse thoroughly with clean water, then move on to your contact wash.

Aftercare

  1. Follow with a contact wash using a pH neutral shampoo and a clean wash mitt.
  2. Rinse spray bottles and foam lances through with clean water after use.
  3. Label any bottle of diluted Grime with the ratio you mixed.
  4. After interior APC use, wipe the area over with a clean, damp microfibre towel.
  5. Store the concentrate sealed and upright, away from heat and frost.

The Brand

Alchemy

Alchemy Car Care was developed from what the company describes as years of grassroots detailing experience. Rather than building the range around a catalogue of existing products, Alchemy says its formulas were repeatedly developed, tested, adjusted and tested again before release. Testing was carried out across different vehicles, paint types and paint colours, with the aim of producing products that worked in the way the people behind the brand wanted to use them themselves.

That practical approach is still reflected in the range. Products are generally straightforward in purpose, with clear applications rather than unnecessary overlap between multiple versions of the same chemical.

A Range That Covers the Detailing Process

A Range That Covers the Detailing Process

Alchemy has built a broad car care range covering pre-washing, contact washing, chemical decontamination, paint preparation, polishing, protection, interior cleaning, wheels and tyres. Grime provides the citrus pre-wash stage, Whitewash covers snow foam, Dirty Harry handles contact washing, while Chemical X and Diss-olve tackle iron contamination and tar. Further through the process, One Hit provides single-stage paint correction, with products such as Shell Suit, Duck Tail and Suga Coat covering different methods of adding protection and finishing the vehicle.

The range extends beyond liquids into clay, applicators, microfibres, brushes, buckets and other detailing accessories, allowing Alchemy products to be used through much of a complete exterior and interior detailing process.

Practical Chemistry With Useful Dilution

Practical Chemistry With Useful Dilution

A notable part of Alchemy's cleaning range is its use of concentrated products rather than relying solely on ready-to-use formulas. Grime Citrus Pre-Wash, for example, can be adjusted from around 10:1 for heavier contamination through to 100:1 for lighter cleaning, while also having applications beyond exterior pre-washing. Whitewash Snow Foam and Dirty Harry Shampoo are also sold as concentrated products, allowing the user to alter product strength or quantity according to the level of contamination and the job being carried out.

Alchemy is based in Dewsbury, West Yorkshire, and its range is also distributed to the detailing trade through Linntec. This places it firmly within the UK detailing market, with products covering enthusiast maintenance as well as the larger sizes and concentrated chemicals useful to regular and professional users.
