Cleans very well, and faint smell is gone once it dries - Since I am super sensitive to smells, I was worried about using this product on the inside air handler coils, as it does have a faint fragrance. I used 1 part cleaner to 2 parts water, rinsed it well with a garden hose, only turned on 1/3 (also had a wet vac standing by, in case the drain was overwhelmed, which it didn't), and after it fully dried, there was no smell. Update: After a couple of 100F days, I can report that the system is notably more efficient (the air is colder) after the cleaning, it had been 10 yrs since last cleaning. And there is no smell in house when it runs, if anything, it smells cleaner. I also replaced the start capacitor for the air handler fan. ## Features - Comstar 's coil safe is a premium external neutral pH evaporator indoor rinse cleaner - This non-foaming liquid can be diluted with 3 to 10 parts of water (depending on the level of cleaning required) - It restores heat transferring properties to 100% efficiency by removing lint, grease and dust and dirt build-up without the need for water flushing - Traditional green color, non-acid, non-alkaline, neutral pH, environmentally safe formula - Coil safe cleans and brightens all metal parts and contains inhibitors to prevent metal fatigue ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01D66YNWA | | Best Sellers Rank | #130,277 in Health ( See Top 100 in Health ) #261 in Household Cleaning Metal Polish | | Brand | Comstar | | Brand Name | Comstar | | Capacity | 128 Fluid ounces | | Contains Liquid Contents? | Yes | | Customer Reviews | 4.6 out of 5 stars 1,488 Reviews | | Global Trade Identification Number | 00024924902981 | | Item Form | Liquid | | Item Type Name | Coil Safe Cleaner | | Item Volume | 1 Gallons | | Item form | Liquid | | Item volume | 1 Gallons | | Manufacturer | ComStar International Inc. | | Material Features | Non-Toxic | | Material Type Free | Acid Free | | Material features | Non-Toxic | | Model Number | 90-298 | | Number of Items | 1 | | Part Number | 90-298 | | Scent | Unscented | | Size | 128 Fl Oz (Pack of 1) | | Special Features | No Rinse | | Special Ingredients | Sodium Gluconate | | Specific Uses For Product | Engine | | Specific uses for product | Engine | | Surface Recommendation | Metal | | UPC | 024924902981 | | Unit Count | 3800 Milliliters | ## Product Details - **Brand:** Comstar - **Item form:** Liquid - **Material features:** Non-Toxic - **Scent:** Unscented - **Specific uses for product:** Door ## Images ![90-298 Coil Safe Professional Grade Neutral pH Evaporator and Condenser Coil Cleaner, 1 gal Container, Green - Image 1](https://m.media-amazon.com/images/I/61Tcf0yMCVL.jpg) ## Questions & Answers **Q: Coil safe is us made?** A: This product is manufactured in the U.S. NOT China. **Q: Will this work for a condenser outdoors AC unit?** A: One other thing. This is made for the outdoor AC condenser coils. They DO make one specifically for the evaporator (usually indoors) coils. It's listed near the bottom of the page in the 'comparisons' section. I'd go with that for the evaporator. **Q: Does Coil Safe dissolve hair and dust on the evaporator coil?** A: Coil Safe is not formulated to dissolve hair or dust on an evaporator coil. Evaporator coils are indoors and therefore, the chemicals used on evaporator coils must be safe and not corrosive. Over time, indoor coils will get a buildup of greasy grime. Coil safe is formulated to break down that buildup so it self-rinses off the coil as the liquid drains off the coil. A soft brush or toothbrush can be used to loosen and wipe off very heavy buildup. **Q: can this be used in condensate drain lines** A: COIL SAFE is not a condensate pan drain opener. It is to clean dirt and grime off of evaporator coils. To clean out condensate pan drains use our CONDENSATE PAN DRAIN OPENER. It comes in quart and 1/2 gallon size bottles; stock number 90-315 & 90-316 respectively. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Comstar *by J***S on 23 March 2026* Good! ### ⭐⭐⭐⭐⭐ Highly recommend!

It does dissipate after an hour or so. Would buy again. ## Frequently Bought Together - ComStar Coil Safe, External Neutral pH, Non-Toxic, Self-Rinsing Evaporator Coil Cleaner Compatible With Commercial & Residential AC & Refrigeration System Coils, Made In USA, 1 Gallon (90-298), Green - Advanced Coil Cleaning Fin Brush for AC Evaporator and Condenser Coils – Dual-Sided HVAC Coil Cleaner | Stainless Steel Pins & Soft Bristles | Improve Efficiency, Prevent Build-Up, Easy AC Maintenance - Nu-Calgon 417175 Evap Foam --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.lk/products/778463237-90-298-coil-safe-professional-grade-neutral-ph-evaporator-condenser](https://www.desertcart.lk/products/778463237-90-298-coil-safe-professional-grade-neutral-ph-evaporator-condenser) --- *Product available on Desertcart Sri Lanka* *Store origin: LK* *Last updated: 2026-09-17*
