- /ONE Car Shampoo V4 — the maintenance shampoo to buy first; a neutral, coating-safe suds for the weekly two-bucket wash. The core of the /ONE (clean & maintain) tier.
- /ZERO Iron Oxide V3 — the /ZERO decon remover; dissolves bonded iron fallout and brake dust from paint and wheels, the chemical decon step before protection.
- /ZERO Citrus — highly concentrated citrus (d-limonene) pre-wash and APC for degreasing the heaviest grime before contact washing.
- /ONE Snow Foam V2 — the /ONE pre-wash foam for a touchless first pass through a foam cannon, lifting loose dirt before you touch the paint.
- /TWO Quick Detailer — a /TWO finisher that doubles as a drying aid; adds gloss and light protection between washes with minimal effort.
- /TWO Sigma V3 — step up the /TWO tier for durable ceramic protection when you want longer-lasting hydrophobics.
- /ONE Wheel Shampoo V2 — a dedicated wheel shampoo for safe, regular wheel cleaning alongside the main wash.
How to choose
Read the number first — it tells you the job. /ZERO is preparation (decontamination, degreasing, panel wipe); /ONE is regular cleaning and maintenance (shampoos, foam, wheels); /TWO is protection and finishing (sealants, quick detailers, trim); /THREE is advanced ceramic systems. A complete beginner kit is one product from each job you actually do: /ONE Car Shampoo for every wash, a /ZERO remover for periodic decon, and a /TWO product to protect. Add /ONE Snow Foam if you run a foam cannon, and step into /TWO Sigma or the /THREE ceramics only once your wash routine is dialled in.
FAQ
Where should I start with Garage Therapy?
Start with the /ONE tier — /ONE Car Shampoo V4 for your weekly wash — then add a /ZERO remover (e.g. /ZERO Iron Oxide) for decontamination and a /TWO product such as the Quick Detailer for protection.
What do the numbers /ZERO, /ONE, /TWO, /THREE mean?
They are Garage Therapy's tiers by job: /ZERO prepares and decontaminates, /ONE cleans and maintains, /TWO protects and finishes, and /THREE covers advanced ceramic coatings.
Is Garage Therapy good for beginners?
Yes — the numbered system is designed to make product choice simple, so you pick by the job (prep, wash, protect) rather than by guessing. Begin with one product per job you do.
