Coil Safe's anti-flush and non-foaming formula is essential for restoring coils to their original indoor state. Safe to use on aluminum and copper. Review: Good price here. Used to buy via ezybuy. Kinda troublesome. Now it's sold here. I usually do rinse with fresh water though after using this product. Dilute accordingly. Check the instructions. Review: This worked great with cleaning our heat pumps but it is a bit strong. It does dissipate after an hour or so. Would buy again. ## 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 | | ASIN | B01D66YNWA | | Additives | Sodium Gluconate | | Best Sellers Rank | #188,433 in Health ( See Top 100 in Health ) #338 in Household Cleaning Metal Polish | | Brand | Comstar | | Customer Reviews | 4.6 4.6 out of 5 stars (1,468) | | Customer reviews | 4.6 4.6 out of 5 stars (1,468) | | Date First Available | 5 July 2019 | | Format | Liquid | | Item model number | 90-298 | | Manufacturer | ComStar International Inc. | | Product Dimensions | 15.24 x 15.24 x 30.48 cm; 4 kg | | Product Name | Coil Safe Cleaner | | Units | 3800 Milliliters | | Volume | 1 Gallons | ## Product Details - **Brand:** Comstar - **Item form:** Liquid - **Material features:** Non-Toxic - **Scent:** Unscented - **Specific uses for product:** Door ## Images ![ComStar 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) ## Available Options This product comes in different **Style** options. ## 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 ### ⭐⭐⭐⭐⭐ Review *by N***P on 10 November 2024* Good price here. Used to buy via ezybuy. Kinda troublesome. Now it's sold here. I usually do rinse with fresh water though after using this product. Dilute accordingly. Check the instructions. ### ⭐⭐⭐⭐⭐ Review *by M***N on 29 January 2025* This worked great with cleaning our heat pumps but it is a bit strong. It does dissipate after an hour or so. Would buy again. ### ⭐⭐⭐⭐⭐ Review *by I***N on 25 December 2020* Used this to clean my electronic air cleaner element's for my furnace and the filter for my orik air purifier I bought used years ago. I have never been able to get either clean, I have used dawn and hot water as well as even gave steam cleaning a shot but always had dirt stuck on my filters for my furnace ( these are aluminum so plz do not try to clean paper or any other filter media with this, it is not designed to work on anything else other then metal type filters ), my air purifier filter is also aluminum and when I got it the filter was stained with what I have to assume is tar from cigarettes. I have tried multiple cleaners and none have worked on it either. I put ( in a clean spray bottle ) 1/4 bottle of cleaner with 1/2 bottle of hot water in old windex bottle and sprayed the purifier filter, the junk stuck on there that didn't want to come off, just started running off like using a garden hose to spray mudd off your truck before washing. Side of bottle says to let sit for 5 min after spraying, I let it sit for maybe 2 to see how well it cleaned stuff and then used my shower head to spray the filters down with hot water. I have not seen the dirt run off these filters like this before. I even rinsed the dirt off to start with using the pressure spray on my shower head before spraying the cleaner and I still got double the amount of dirt to come off. When I rinsed the filters the 2nd time, the water rinsed off as much dirt as it did when I first rinsed the filters before spraying them! The air purifier filter, I had chunks coming off of this junk/ tar when I rinsed it. The odor, there is none! I'm serious, there is no odor! This stuff is about as much as the spray calgon I believe is the brand cleaner that claimed to be odorless, but wasn't. This is cheaper and is alot better since there is no fumes or odors! ## 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.is/products/778463237-comstar-90-298-coil-safe-professional-grade-neutral-ph-evaporator](https://www.desertcart.is/products/778463237-comstar-90-298-coil-safe-professional-grade-neutral-ph-evaporator) --- *Product available on Desertcart Iceland* *Store origin: IS* *Last updated: 2026-04-29*
