Fuel tank sludge removers are chemical additives designed to dissolve and eliminate sludge, varnish, and deposits in fuel systems. They help restore fuel efficiency, improve engine performance, and prevent clogging in fuel injectors and filters. These products are commonly used in automotive, marine, and industrial fuel systems.

Size: Typically available in 250ml to 1-liter containers for consumer use; industrial variants may range up to 20 liters.

Grade: Conforms to ASTM D975, EN 590, and ISO 4406 standards for fuel cleanliness.

Viscosity: Low viscosity (5-15 cSt at 40°C) for easy flow and dispersion in fuel systems.

Buoyancy: Negligible buoyancy as it dissolves/disperses in fuel rather than floating.

Material: Petroleum-based solvents, surfactants, and detergents; may include polyisobutylene or alkylamine additives.

Compatibility: Suitable for diesel, biodiesel (B20/B100), and gasoline fuel systems.

Operating Temperature: -30°C to 100°C for stable performance.

Flash Point: Typically >60°C (Pensky-Martens closed cup) for safety.

Density: 0.8-0.9 g/cm³, similar to hydrocarbon fuels.

Packaging: HDPE or metal containers to prevent chemical degradation.
