10 Best Mini Split Coil Cleaners 2026 in the United States

The Simple Green Foaming Coil Cleaner is a cleaning agent designed specifically for foaming coils, and it comes in a 128 Fl Oz gallon size. As a foaming cleaner, it works effectively to remove dirt, grease, and other residues from coils, ensuring efficient performance of mini-split systems. The unscented formula is beneficial for users who prefer products without any added fragrances, making it a safe choice for environments sensitive to smells.

Its ease of use is enhanced by its liquid form, which allows for straightforward application directly onto coils. The foaming action ensures comprehensive coverage and penetration, aiding in thorough cleaning. However, the product package dimensions and weight (8.88 pounds) could make handling slightly cumbersome for some users, especially during application.

Safety-wise, being a product from a reputable manufacturer like Simple Green, it meets typical safety standards, but users should still follow proper handling instructions to avoid any potential hazards. It primarily focuses on cleaning foaming coils, making it highly effective for maintaining mini-split systems. This cleaner is ideal for homeowners and professionals looking for a reliable, unscented cleaning solution for their HVAC systems.
