Great Stuff Foam Cleaner 12 oz — spray solvent for uncured polyurethane foam, portable aerosol for foam-gun maintenance

Great Stuff Foam Cleaner 12oz is a portable solvent spray formulated to remove uncured spray polyurethane foam and clean foam-gun applicators, tip-to-tip.

When working with expanding polyurethane sealants and insulating foams, quick and effective cleanup keeps tools reusable and surfaces blemish-free. This 12-ounce aerosol is sized for the jobsite or workshop, providing targeted solvent action to dissolve fresh foam, dissolve tack, and flush applicator components before the foam cures. It’s intended for use on uncured foam only — cured foam generally requires mechanical removal.

How does this cleaner help when a foam job goes off-plan?

At the moment excess wet foam gets where it shouldn’t, an accessible aerosol cleaner reduces waste and prevents hardened residue. Spray directly onto the uncured foam or onto a cloth to lift and wipe away tacky material, and follow with a second application to flush applicators.

• Removes uncured polyurethane foam from tools and surfaces.
• Quick-drying solvent action reduces downtime on jobs.
• 12 oz aerosol fits in a toolbox or job pouch for convenient access.

Can I use it to maintain foam-gun applicators and nozzles?

Yes — frequent cleaning of foam guns extends their usable life and prevents blockages. Spray into the gun body and through nozzles to dissolve uncured foam before it hardens; wipe exterior parts with a solvent-soaked rag for best results.

• Flushes feed passages and nozzle openings to keep flow consistent.
• Helps maintain trigger mechanisms and seals when used promptly after application.
• Portable size allows on-site maintenance between passes.

What surfaces and materials does this product work on, and what should I avoid?

The cleaner is designed for fresh polyurethane foam on typical construction materials like wood, metal, and many plastics. Because it is a solvent aerosol, avoid extended contact with painted finishes, delicate plastics, fabrics, and rubber unless you test a hidden area first.

• Safe for removing uncured foam from many hard surfaces — test sensitive finishes first.
• Not intended to dissolve cured foam — mechanical removal or dedicated cutters required.
• Avoid inhalation and skin contact; use in a ventilated area.

How do I use this aerosol safely and effectively?

Use personal protective equipment and ventilate the area. Shake the can, spray directly on uncured foam or onto a clean rag, and allow the solvent to penetrate briefly before wiping or flushing. For applicators, spray through the feed or nozzle until residual foam clears, then reassemble the gun while dry.

• Wear gloves and eye protection when spraying and wiping.
• Work outdoors or in well-ventilated spaces to minimize fume exposure.
• Follow local disposal regulations for empty cans and used rags.

Who is this for? Great Stuff Foam Cleaner 12oz is aimed at contractors, remodelers, and DIYers who regularly use spray polyurethane foam and need a compact, jobsite-ready solvent to remove uncured foam and maintain applicators. If you frequently apply expanding foam and want to reduce tool replacement and surface repairs, keeping a dedicated cleaner in your kit helps preserve equipment and speeds cleanup. For cured foam removal, consider mechanical tools or specialized cutters; this product is optimized for fresh cleanup and tool maintenance.
