Both products share the same non-chlorinated formula and are suitable for the same applications. The 5 litre tin is designed for professional workshop use where large volumes of brake cleaner are required regularly, offering a significantly lower cost per litre than the aerosol format. The 600ml aerosol is better suited to occasional use and offers the convenience of a pressurised spray for precise, targeted application in hard-to-reach areas. Is Quinton Hazell QH6 non-chlorinated? Yes. The QH6 uses a hydrocarbon-based formula and contains no chlorinated solvents, as confirmed on the product label. Non-chlorinated formulas are generally considered safer for the user and the environment than chlorinated alternatives, while still delivering powerful and effective cleaning performance on brake and clutch components. What surfaces is the QH6 5L suitable for? Quinton Hazell QH6 is suitable for use on brake discs, pads, calipers, drums, brake cylinders, clutch plates and friction surfaces, as well as starters, alternators, carburettors and general engine parts. Note that rubber and plastic components should not be immersed in the solvent and it should not be applied to hot engine or brake parts. Can I use QH6 without disassembling the brakes? Yes. QH6 is designed for in-situ cleaning, meaning it can be applied directly to brake and clutch components without disassembly. Apply to the surface, allow the solvent to carry away the contamination and leave to dry before reassembly. Always use in a well-ventilated area. Is the QH6 5L for professional use only? Yes. As stated on the product label, the QH6 5L tin is intended for professional use only. The 600ml aerosol version is available for both professional and general automotive use. Always follow the safety instructions on the label including the use of appropriate PPE such as gloves and eye protection.
