Q²M APC 1000ml – All Purpose Cleaner | GYEON

What Is Q²M APC

Q²M APC is GYEON's all-purpose automotive cleaner, engineered around one principle: one product, every surface, complete control over cleaning intensity. The 1-liter size is the practical choice for car enthusiasts who detail their own vehicles at home or need a dependable multi-surface cleaner for occasional deep-cleaning sessions.

How It Works

What sets Q²M APC apart from standard cleaners is its dilution-based system. Rather than applying a fixed-strength formula, you control how aggressive the cleaning action is by adjusting the ratio before each use. A 1:5 concentration delivers the strength needed to cut through heavy exterior soiling on wheel arches, door sills, and undercarriage surfaces. Brought down to 1:15, the same product becomes gentle enough for dashboard panels, fabric floor mats, and upholstered surfaces without the risk of discoloration or residue.

Getting the Most Out of It

For heavily contaminated vehicles, combining Q²M APC with Q²M Foam through a foam lance creates a powerful pre-wash stage that loosens surface grime before any contact washing begins — protecting your paintwork by reducing the risk of swirl marks during the wash process.

Important Usage Note

When using this product on any unfamiliar surface for the first time, always begin at the weakest dilution and increase gradually only if needed. Do not allow the solution to dwell on the surface until dry.
