Labocosmetica Dilution Ratio Cheat Sheet — Every Product, Every Use Case
Every Labocosmetica product, every dilution, every use case.
Labocosmetica products are concentrated. A 500ml bottle of Semper makes 750 litres of ready-to-use shampoo at the correct ratio. Get dilution right and chemistry works. Get it wrong and you either waste the concentrate or risk cosmetic damage. This is our workshop reference — now public.
Why dilution ratios matter
Chemistry
Most products rely on a specific active-ingredient concentration. Too dilute and the chemistry can't complete its reaction before drying.
Safety
Acid, alkaline, iron-remover, APC — all have surface-damage risk above the safe concentration range for the substrate.
Economy
A 500ml bottle of Semper is 750 L of ready-to-use shampoo at 1:1500. Getting the ratio wrong costs you 150× more concentrate for no performance gain.
What follows is organised by product category — washing, decontamination, clay and film prep, interior, leather. Each entry lists the product, every dilution ratio we recommend, and the use case that ratio is for.

Do not dilute — molecular structure depends on it
Mixing the right dilution — a practical method
Dilution ratios are written as a proportion — 1:10 means one part product to ten parts water. To mix 1 litre of a 1:10 solution, you need approximately 91ml of product and 909ml of water (so product + water = 1000ml total). For 1:1500 in a 10-litre wash bucket, that's approximately 6.6ml — effectively a teaspoon.
Use a measuring cylinder for critical ratios (decontamination, coating-booster). For wash buckets at dilute ratios, a kitchen measuring spoon and a visual check is enough.
Mix the water first, then add the product, then agitate gently. This prevents the concentrate from coating the walls of the container before the water disperses it.
⚠ Safety tips that apply across the range
Never apply acid or alkaline products in direct sunlight. Temperature accelerates chemistry. Direct UV plus a hot panel plus an acidic or alkaline product is how cosmetic damage happens. Move the car into shade or rinse panels with cool water to drop surface temperature below 35°C before chemistry.
Never let acid or alkaline products dry on paint. If a panel starts drying before rinsing, mist with fresh water to keep the chemistry active.
Wear nitrile gloves when working with Sidero, Energo, Purifica, Primus 2.0, or Ductile at their stronger dilution ranges.
Test on a hidden area for any acid or alkaline chemistry you're using for the first time on unfamiliar paint. Single-stage, soft, or delicate finishes can respond differently to modern clearcoats.
◈ Why these ratios work — the chemistry context
Labocosmetica's dilution ratios are very dilute for a specific reason: their concentrates are formulated with highly active, highly pure surfactant and chemistry systems. You don't need more molecules per litre of working solution because each molecule is more effective. This is the same principle as comparing a weak, cheap shampoo (lots of filler, low active content) to a premium concentrate (minimal filler, high active content).
For Semper, the 1:1500 ratio comes from a single-ingredient non-ionic surfactant concentrate — essentially nothing but cleaning active content. For Primus 2.0, the VDA-certified alkaline chemistry works at lower free-alkalinity concentrations than caustic competitors can achieve. For Revitax, siloxane active content is already bonded to carrier micelles at the right molecular concentration for paint contact.
