// The Formulation Story

PROTECT THE HEART OF YOUR HOT WATER WASHER.

SURFACE TRANSFORMATION WITHOUT MECHANICAL ABRASION.Standard detergents rely on high foam. Alkota master formulations attack the electrostatic and oily bonds that hold grime to metal and paintwork.

Hard water minerals crystalise inside heating coils under extreme temperatures, restricting flow and leading to premature coil burnout. ScaleGuard sequesters calcium and magnesium before scale can adhere to the steel.

When high-pressure water alone hits road film or engine grease, it shears off the loose top layer while leaving behind a dull static film.

ScaleGuard Water Softener & Coil Protector is built around the authentic SD-927 (No Scale) formulation. Developed across fifty years of American hot-water pressure washing, it features heat-stable surfactants that saponify oils and suspend dirt in the rinse stream before it can redeposit.

01 // Synergy

Hot Water Activated

Surfactants accelerate above 50°C without breaking down.

02 // Machine Safe

Coil & Pump Friendly

Non-crystallising in high-pressure valves and heating coils.

03 // Traceable

100% GB-CLP Pure

Fully registered with verified UK safety dossiers.

// Chemical Action

How It Works on the Surface.

1. Wetting & Penetration

Lowers water surface tension to penetrate micro-crevices in paintwork, metal castings, and chassis rails.

2. Hydrocarbon Saponification

Active surfactants break heavy petroleum oils, diesel grime, and organic fats into water-soluble compounds.

3. Soil Suspension & Rinsing

Holds released dirt particles in suspension so they rinse cleanly away without streaking or re-adhering.

Master Code:SD-927
// Target Soils

The grime it dissolves.

Formulated specifically to dissolve stubborn environmental residues, baked soot, and oily binders that resist ordinary soap.

// Standard Operating Protocol

Three Steps to a Perfect Clean.

Engineered for high chemical induction efficiency. Follow the exact protocol for maximum cleaning speed and minimum chemical wastage.

01Phase: Metering

DILUTE

Verified Dilution Ratio:

Dosed via automatic machine scale pump reservoir.

Calibrate your pressure washer downstream injector or foam cannon metering valve to match your local water hardness.
02Phase: Application

APPLY & DWELL

Application Method:

Pour into machine anti-scale dosing tank.

Apply uniformly from bottom to top to prevent chemical streaking. Allow 2–3 minutes contact dwell without letting dry.
03Phase: High Pressure Rinse

RINSE & FLUSH

Optimal Rinse Profile:

High pressure water blast (150–200 BAR). 50°C–65°C hot water dramatically accelerates soil release.

Rinse thoroughly from top to bottom. Surfaces will sheet freely without chalky detergent residues.
Safety & Handling:Non-hazardous under CLP at ready-to-use levels. Do not ingest.
