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.

Frequently Asked Questions

What dilution should I use?

Alchemy recommends 10:1 for heavy soiling, 50:1 for medium soiling and 100:1 for light soiling. Grime is a concentrate, so you dilute it to suit the job.

Will Grime strip my wax or sealant?

No, Alchemy states Grime will not strip wax or sealants.

Can I use it in a snow foam lance?

What does Grime remove?

Can I use it inside the car?

Alchemy wash, decontamination and protection

Wash. Grime Citrus Pre-Wash dilutes 10:1 (water to Grime) for heavy dirt, 50:1 for medium and 100:1 for light, and can be sprayed or used through a foam lance; Alchemy says it is safe on wax and sealant. Whitewash Snow Foam is pH-neutral, at 5:1 water to foam for heavy cleaning. Dirty Harry is a pH-neutral, wax-friendly shampoo: one capful per litre of water, used on a cool panel out of direct sun. Dry with the Alchemy Dry towel, 90 x 75cm in a twisted loop pile, or wash with the microfibre wash pad.

Wheels and decontamination. Supreme Wheel Cleaner is acid-free: neat for heavy dirt or diluted 1:5 to 1:10 for light, left for one minute, then rinsed. Chemical X is a ready-to-use, pH-neutral gel that turns red as it reacts with iron fallout; apply to cool wheels and rinse within five minutes. Qube Soft Clay (100g) lifts overspray and tar for regular use, with Qube Lube as its pH-balanced lubricant.

Gloss and protection. Dark Matter and Light Matter are glazes matched to dark and light paint, hiding light blemishes by hand or machine. Supanova is a soft wax and oil blend for show gloss, Ceramic Wax is a hybrid paste wax that Alchemy rates at up to 12 months, and Duck Tail is a ceramic wet-coat spray, rated at up to four months. Suga Coat is a hydrophobic quick detailer for between washes.

Shop by type: citrus pre-wash, snow foam, wheel cleaners, glazes and car waxes.

Alchemy interior care, odour bombs and brushes

Alchemy interior care, odour bombs and brushes

Interior and glass. So Clean is an anti-static interior cleaner for plastics that leaves a matte finish and a fresh smell and helps stop new dust settling. Cosmos Glass Cleaner is a fast-evaporating blend of distilled solvents for grease, fingerprints and vape residue, and Alchemy says it is safe on acrylic, Plexiglas and tinted windows. For tyres, Soul Glo 2000 is a silicone oil gel: a few drops per tyre bring back the deep black.

Re-Fresh odour bombs. Each 150ml Re-Fresh can treats bacteria and odours through the whole cabin and the air conditioning, not just masking them: run the blower on high in recirculation, empty the can and leave the car unoccupied during the treatment. Scents: Watermelon, Bubblegum, Cherry Bomb, Linen, New Car and So Cool.

Brushes. The GLO Brush Set pairs a large 24cm and a small 16cm brush with super-soft, metal-free bristles for badges, screens, dashboards, vents and gauges; the handles glow in the dark after charging in daylight (also in green). The MultiBrush Pro has two weighted handles and five twist-on heads, and the boar's hair set gives five sizes for vents, door shuts, badges and wheels.

Shop by type: interior cleaners, odour and smoke eliminators and brush sets.
