RM 838 Direct Foam Cleaner 3L, 6.295-979.0, Karcher

RM 838 Direct Foam Cleaner 3L is a concentrated foam cleaning solution for efficient removal of dirt, grease and road film from vehicle exteriors and other hard surfaces. Developed for use with Karcher pressure washers and foam lances, this 3‑litre formulation produces stable foam that clings to vertical surfaces to improve contact time and cleaning performance. The product is suitable for routine wash cycles where effective degreasing and gentle surface care are required.

Advantages

The cleaner forms stable, clingable foam that increases dwell time and improves dirt lift while minimising streaking. Its formulation is effective against oils, grease and common road contaminants yet is compatible with typical automotive paints and lacquered finishes when used according to instructions. The 3‑litre container offers a balance between professional volume and manageable handling for service bays and mobile cleaning tasks.

Suitable for

• Exterior car body washing with foam lances
• Cleaning of vans, trucks and motorcycles
• Degreasing painted and lacquered surfaces before detailing
• Use on workshop floors and other hard surfaces requiring foam application

Key specifications

• Form: concentrated liquid for dilution
• Volume: 3 litres
• Foam behaviour: high-foaming, clingable foam
• Compatibility: formulated for use with pressure washer foam systems
• Primary action: degreasing and surface soil removal

How to use

Dilute the concentrate according to application and equipment instructions, typically in the foam lance or proportioning system of a pressure washer. Apply foam evenly over the target surface and allow sufficient dwell time for the foam to break down and loosen dirt and grease. Rinse thoroughly with clean water and, if necessary, repeat spot treatment for heavily soiled areas. Follow any equipment-specific instructions for dilution ratios and application pressures.

Usage recommendations

Use appropriate personal protective equipment when handling concentrates. Test on an inconspicuous area before full application on sensitive surfaces. Do not apply in direct sunlight or on hot surfaces to avoid rapid drying of foam. Store the product in a cool, dry place away from frost and direct heat sources.
