HEAVY-DUTY CONDENSER COIL CLEANER
COIL BLAST™
High-foaming professional cleaning power for heavily contaminated outdoor condenser coils.
COBRA Coil Blast is a professional heavy-duty condenser coil cleaner designed to penetrate and loosen grease, oil, road film, soot, dirt and industrial contamination from outdoor HVAC coils. Its high-foaming action helps maintain contact with vertical coil surfaces and reach between fins, allowing loosened contamination to be removed during the required clean-water rinse. Coil Blast is aluminum safe and micro-channel safe when used as directed.
KEY BENEFITS
BUILT FOR HEAVY CONTAMINATION
Professional cleaning performance for demanding outdoor condenser-coil applications.

Heavy-Duty Cleaning
Designed for demanding outdoor condenser-coil contamination.

High-Foaming Action
Foam helps maintain contact with vertical coil surfaces and penetrate between fins.

Deep Penetration
Helps loosen embedded dirt, grease, oil, soot and accumulated deposits.

Fast Acting
Recommended dwell time of approximately 5-15 minutes.

Aluminum Safe
Suitable for aluminum condenser-coil applications when used as directed.

Micro-Channel Safe
Suitable for micro-channel condenser applications when used as directed.

Professional Grade
Developed for HVAC technicians, contractors and facility-maintenance applications.

Rinse-Clean Finish
Loosened contamination and cleaner residue are removed with a thorough clean-water rinse.

Supports Coil Performance
Routine cleaning helps maintain open airflow passages and clean heat-transfer surfaces.
RECOMMENDED APPLICATIONS
- ✓ Outdoor air-conditioning condenser coils
- ✓ Split AC outdoor units
- ✓ Packaged air-conditioning condenser coils
- ✓ Rooftop HVAC condensing units
- ✓ Air-cooled heat exchangers
- ✓ Commercial HVAC condensers
- ✓ Industrial cooling equipment
- ✓ Micro-channel condenser coils
TYPICAL CONTAMINATION
- ✓ Heavy grease
- ✓ Oil deposits
- ✓ Road film
- ✓ Soot and greasy particulate buildup
- ✓ Dust and dirt
- ✓ Atmospheric contamination
- ✓ Industrial deposits
- ✓ General outdoor coil contamination
WHY CONDENSER COIL CLEANING MATTERS
Outdoor condenser coils continuously draw ambient air across their fins and can accumulate dust, grease, fibers and environmental contamination. Buildup can restrict airflow and insulate heat-transfer surfaces.
HOW TO USE
DIRECTIONS FOR USE
- 1. Turn off and completely disconnect all electrical power to the outdoor HVAC unit before starting.
- 2. Remove loose leaves, debris or easily removable surface contamination where practical.
- 3. Spray COBRA Coil Blast directly and evenly onto the dry condenser coil, ensuring complete coverage. Use a foam-producing spray pattern for best results.
- 4. Allow the foam to remain on the coil for approximately 5-15 minutes.
- 5. Do not allow the product to dry on the treated coil surface.
- 6. Rinse thoroughly with clean water until loosened contaminants and residue are removed.
- 7. Inspect the coil, surrounding components and drainage path.
- 8. Restore electrical power only after rinsing, drainage and inspection are complete.
NOTE: Coil Blast 950ml requires rinsing. Always rinse the treated condenser coil thoroughly with clean water after the recommended dwell time.
