CoilShot Coil Cleaner Tablets (for Heavy Duty cleaning & degreasing) - Replaces bulky heavy liquid coil cleaner. The revolutionary CoilShot cleaning system is designed to offer fast and easy cleaning of commercial single-pass HVAC coils without the strain and bulkiness of using liquid coil cleaners.

• Degreases and brightens coils
• For heavy duty applications

These are not recommended for use on microchannel coils and should not be used around ponds or aquatic life (similar to a heavy duty wheel cleaner with a Ph of 12). The CoilShot tool should be flushed for approx 3 minutes with water after using the HD tablets. For most residential use, especially around plants, I'd recommend using the standard tablets.
