5. Operating Instructions
5.1. General Use (Ovens, Grills, Range Hoods)
- Application: Apply Suma Foam Free cleaner directly to the surface using the foaming sprayer.
- Dwell Time: Allow the product to remain on the surface for several minutes.
- Optimal Temperature: For best results, use on a warm surface (120-150°F / 49-66°C).
- Scrubbing: Scrub the surface with a brush, cloth, or scrubbing pad to loosen soils.
- Rinsing: Rinse thoroughly with potable water.
- Drying: Allow the surface to air dry completely.
- Food Contact Surfaces: If the cleaned surface is for food contact, it must be sanitized according to local, state, and federal requirements after cleaning.
5.2. Fryer Cleaning
- Turn Off Fryer: Ensure the fryer is turned off before beginning the cleaning process.
- Drain Oil: Drain all oil from the fryer and close the drain valve.
- Remove Loose Soil: Use a brush to manually remove any loose, gross soil from the interior walls of the fryer.
- Fill with Water: Fill the fryer with clean water to approximately the oil fill level.
- Add Cleaner: Add Suma Foam Free to the water. For a 40 lb capacity fryer, use 2 full bottles of Suma Foam Free. Adjust the dose accordingly for significantly larger or smaller capacity fryers.
- Heat Solution: Turn on the fryer and heat the cleaning solution to 200°F (93°C).
- Monitor Temperature: Monitor the cleaning cycle to ensure the temperature does not exceed 200°F (93°C), as exceeding this temperature will cause the solution to boil and foam excessively.
- Dwell Time: Allow the solution to work for 20 minutes.
- Turn Off Fryer: After 20 minutes, turn the fryer off.
- Drain Solution: Drain the cleaning solution from the fryer.
- Rinse: Rinse the fryer thoroughly with clean hot water.
- Dry: Allow the fryer to air dry.
- Refill: Close the drain valve prior to refilling with oil.
6. Maintenance
Proper storage ensures the longevity and effectiveness of the product:
- Storage Conditions: Store the product in a cool, dry place.
- Avoid Extremes: Keep away from direct sunlight and extreme temperatures.
- Container Integrity: Ensure the container is tightly closed when not in use to prevent evaporation or contamination.
- Incompatible Materials: Store away from incompatible materials as indicated on the product label.
7. Troubleshooting
If you encounter issues during cleaning, consider the following:
- Ineffective Cleaning: If cleaning results are unsatisfactory, verify that the product was applied for the recommended dwell time, at the optimal temperature (for general use), and with sufficient scrubbing.
- Persistent Stains: For heavily soiled or persistent stains, a second application and extended dwell time may be necessary.
- Surface Damage: Immediately cease use if any adverse reaction or damage to the surface is observed. Refer to the "Incompatible Surfaces" section in the Safety Information.
- Excessive Foaming (Fryer Cleaning): If the cleaning solution in the fryer foams excessively, the temperature likely exceeded 200°F (93°C). Turn off the heat and allow the solution to cool slightly before resuming.
