Foam gun cleaner FISCHER 4006209531464 — solvent for cleaning polyurethane foam guns

FISCHER foam gun cleaner is a liquid solvent formulated to remove uncured polyurethane foam and residues from foam dispensing guns. Designed for maintenance of professional and domestic tools, the cleaner dissolves deposits inside barrels, nozzles and valves so that foam guns remain operational and less prone to clogging. Regular use after application helps preserve precise dosing and prolong the working life of the equipment.

Advantages

The cleaner effectively dissolves uncured polyurethane foam and softens hardened residues, enabling faster and more thorough cleaning without disassembling complex gun components. Its formulation is suitable for repeated maintenance, reduces the need for replacement parts caused by blockages, and supports consistent gun performance. The liquid format allows targeted application into small openings and valve assemblies.

Suitable for

• Maintenance of manual and pneumatic foam dispensing guns
• Cleaning of nozzles, valves and barrels after polyurethane foam application
• Preventive care to avoid blockages and ensure consistent foam flow
• Use in construction, insulation, sealing and general DIY tasks involving PU foam

Key specifications

• Physical form: liquid solvent suitable for targeted application into gun components
• Compatibility: formulated for use with polyurethane foam residues
• Application areas: internal gun barrels, nozzles, valve mechanisms and small orifices
• Intended users: suitable for professional tradespeople and DIY users caring for foam guns

How to use

After completing foam application, follow the gun manufacturer's guidance and apply the cleaner into the gun's inlet or nozzle according to the product instructions. Operate the gun briefly to circulate the solvent through internal passages, allowing the cleaner to dissolve fresh foam residues. For stubborn blockages, allow the solvent to act for a short period before repeating application or performing careful mechanical cleaning as necessary. Always follow safety instructions and ensure adequate ventilation when using solvents.

Usage recommendations

Use the cleaner promptly after foam application to prevent curing inside the gun. Wear appropriate protective gloves and eye protection, avoid inhalation of vapours, and store the product in a cool, well-ventilated place away from ignition sources. Do not use on cured foam; for hardened residues, combine solvent treatment with mechanical removal following safety guidance.
