Left no residue and evaporated completely with vacuum. ### ⭐ This is a detergent NOT a flush solvent ..! *by M***Y on 16 May 2025* This is a detergent NOT a flush solvent It kills a two ton ac in less than 10 minutes And the item is even NOT RETURNABLE!! angry ### ⭐⭐⭐⭐⭐ Made to do the job correctly. *by T***R on 4 August 2026* This was a good choice to flush my evaporator coil with the flush kit I bought. Some say it is oily, but after flushing with a third of the bottle each time it came out clear and dried fairly quickly when blowing air through to help dry it out. If yoy are going to flush out lines and condensor you may need to buy the gallon size as you can use alot flush quickly, but, it is cheaper than using the cans if you have or get a flush kit with the canister to spray it through the system. ## Frequently Bought Together - Mastercool 91049-128-4 Black/Yellow Flush Solvent, 4 Pack (1 Gallon) - Mastercool 69900 "Mastercleanse Flush Machine, 1 Pack - Mastercool 69925 Multiple Flushing and Leak Test Adapter Kit for Flush Machine, 1 Pack --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.no/products/306281825-mastercool-91049-128-4-black-yellow-flush-solvent-4-pack](https://www.desertcart.no/products/306281825-mastercool-91049-128-4-black-yellow-flush-solvent-4-pack) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-09-22*
