Leak Saver Foam Blaster AC Coil Cleaner Spray — Expanding Foam, No-Rinse Evaporator & Light-Rinse Condenser

Leak Saver Foam Blaster is a high-pressure, expanding foam AC coil cleaner that penetrates deep into evaporator and condenser coils to dissolve grime and deodorize without scrubbing.

This concentrated, professional-strength spray is formulated to drive cleaning agents into tight coil fins before activating as a foaming cleaner that liquefies dirt and oils. Designed for both no-rinse evaporator use and light-rinse condenser service, Foam Blaster is made for HVAC technicians and DIYers who need a powerful, time-saving cleaner for air conditioning and refrigeration systems.

How does Foam Blaster reach buildup that surface sprays miss?

Foam Blaster uses a focused, high-pressure spray that forces the solution into coil channels and crevices, then triggers an expanding foam action. That delayed foaming lifts embedded grime rather than leaving a surface film, improving overall contact with contaminants.

• High-speed, narrow spray pattern for deeper penetration
• Foam expansion activates after solution seeps into buildup
• Liquifies oils and trapped debris for easier removal
• Mild fresh scent left behind after cleaning

Can I use it on both evaporator and condenser coils?

Yes — Leak Saver Foam Blaster is formulated for evaporator coils (no rinse required) and condenser coils (light rinse recommended). For evaporators, normal condensate flow during operation rinses away loosened grime; condensers should be lightly hosed down after treatment to remove loosened soil.

• Evaporators: apply, allow condensate to rinse during operation
• Condensers: apply, then perform a light water rinse
• Safe for HVAC, refrigeration, automotive radiators, and metal filters
• Works on mini-splits, rooftop units, refrigerators, and more

What kinds of soils and surfaces does it handle effectively?

Foam Blaster targets accumulated dust, grease, oily residue, and organic buildup that reduce heat transfer in coils. The heavy-duty chemical blend is optimized to liquefy these deposits without requiring aggressive brushing, making it suitable for delicate fins and tight coil passages.

• Liquifies grease, dust, and organic deposits
• Safe on aluminum and copper coils when used per instructions
• Also useful on fan blades, metal filters, and radiators
• Reduces odors by removing trapped contaminants

How do HVAC pros use Foam Blaster on a service call?

Technicians commonly apply Foam Blaster with the included spray actuator to target coil rows and drain pans, allow dwell time for expansion and breakdown of grime, then rinse where required. Its concentrated action reduces manual scrubbing and speeds up turnaround on routine coil maintenance jobs.

• Apply with focused spray to coil surface and drain pan
• Allow foam to expand and liquefy soils for recommended dwell time
• Rinse condensers lightly; evaporators rinse via condensate flow
• Ideal for repeat service use and preventive maintenance

Who is this for: Leak Saver Foam Blaster is for HVAC technicians, maintenance teams, and informed homeowners who need a professional-grade coil cleaner that reaches tight coil channels and reduces labor. If you maintain mini-splits, central air systems, refrigeration units, or automotive cooling components and want a concentrated no-scrub option for evaporators and a rinsable solution for condensers, Foam Blaster is designed to deliver quick, deep-cleaning performance when used according to label directions.
