Car maintenance spray that cleans carburettors and related parts to restore performance and fuel efficiency, OB41 Carburettor Cleaner. Home mechanics and classic car owners should expect reduced hesitation and smoother idling after treatment. Will a single 400ml can tackle stubborn blockages and sticky linkages?
⚡ At a Glance
- • Cleaning Power: Quickly removes carbon, varnish and fuel deposits from carburettor components
- • Best for: Home mechanics, classic car owners and small-engine maintenance
- • Not ideal for: Major engine overhauls that require part replacement rather than cleaning
A blend of powerful cleaning solvents targets deposits on carburettors and associated parts. Lead and silicone free formulation is described as safe for emissions equipment.
Clears blocked jets and passages - with a powerful solvent blend
A blend of powerful cleaning solvents dissolves carbon, varnish and fuel residues, loosening deposits on throttle plates, jets and heat risers. Action reaches fine capillaries and linkages to restore flow.
Improved throttle response and steadier idle follow a thorough clean; fine capillaries and jets are more likely to operate as intended.
Improves fuel system efficiency - thanks to effective contaminant removal
Removing built-up contaminants helps restore consistent fuel delivery through carburettors and PCV valves, reducing mixture disturbances caused by blockages. Cleaner passages aid more even fuel flow.
Smoother acceleration and more consistent running can result, making routine maintenance more effective at maintaining fuel economy.
Safe for emissions components - with a lead and silicone free formula
Formulated without lead or silicone and noted as not harming catalytic converters, oxygen sensors or fuel injectors in the description. Suitable for vehicles fitted with standard emissions equipment.
Use on cars with catalysts and sensors without risking damage, so carburettor cleaning can be part of regular maintenance for road-going vehicles.
