With its improved formulation, this 945 mL cleaner effectively eliminates various flux types while being safe on plastics and evaporating quickly, making it an essential tool for maintaining PC boards. ## Description Use when a general-purpose zero residue flux remover is required Removes rosin, non-rosin, and no clean fluxes as well as ionic and non-ionic residues. Safe on plastics Fast evaporation highly flammable Review: Magic in a bottle - Move over IPA! - This works flawlessly. Easy to apply, and eats through even the toughest of flux residue. I recently tried out some new solder on a test board, and this solder had some god awful quality “rosin” core. My usual 99% IPA wasn’t anywhere near strong enough to shift it. If anything, all it did was smear it in, and make an even bigger mess of the board, leaving a very sticky, grimey residue. This stuff however, cleans off the flux like it wasn’t even there in the first place. I will note, there is probably a technique to how you use this. I personally used an ESD brush, and painted it on to the PCB over the kitchen sink. I then thought it would be wise to rinse it off with some IPA. (Remember what I said about the IPA earlier?) well, the flux re-accumulated on the board, and in the kitchen sink. Leaving that horrible residue everywhere! So for my next round, I reapplied the flux remover (with the same brush) and dabbed it dry with a paper towel. This time, no mess, and I was pleasantly surprised to see a nice clean PCB afterwards. This stuff does have a little bit of a scent to it, but it’s nowhere near as pungent as my 99% IPA is. Given that most of my soldering supplies are from desertcart (flux and solder) you can’t always garuntee that they will clean off the way they say they will. In fact, most of the stuff I purchased said IPA would do the job; it didn’t. But I am certain this stuff will take care of it all! Well worth the money. And should I run out, I’d get more in a heartbeat! Review: Goodbye Flux! - Bought the quart bottle (non-aerosol). I use this product in the final cleaning step after using 91% rubbing alcohol because it is expensive but works really well. As others have mentioned, brushing goes a long way towards breaking up flux and releasing it from the PCB. Best advice is to wipe away excess flux then soak the board in a shallow pan or dish for a few minutes then work at it with a brush. The goal is to save solvent and clean the board! Do this a few times before rinsing with solvent or alcohol. After the PCB dries, inspect and work on problem areas again. ## Features - Use when a general-purpose zero residue flux remover is required - Removes rosin, non-rosin, and no clean fluxes as well as ionic and non-ionic residues. - Safe on plastics - Fast evaporation - highly flammable ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07XDCRLR6 | | Brand | MG Chemicals | | Brand Name | MG Chemicals | | Contains Liquid Contents? | Yes | | Customer Reviews | 4.6 out of 5 stars 211 Reviews | | Global Trade Identification Number | 00779008414088 | | Included Components | Satisfaction | | Item Form | Liquid | | Item Volume | 1 Litres | | Item Weight | 0.7 Kilograms | | Manufacturer | MG Chemicals | | Model Number | 4140A-945ML | | Net Quantity | 945.0 Milliliters | | Number of Items | 1 | | Part Number | 4140A-945ML | | Size | 945 ml (Pack of 1) | | Special Feature | Evaporates Quickly | | Special Features | Evaporates Quickly | | UPC | 779008414088 | | Unit Count | 945.0 Milliliters | ## Product Details - **Brand:** MG Chemicals - **Item Form:** Liquid - **Item Volume:** 1 Litres - **Net Quantity:** 945.0 millilitre - **Special Feature:** Evaporates Quickly - **Number of Items:** 1 - **Item Weight:** 0.7 Kilograms - **Contains Liquid Contents:** Yes - **Global Trade Identification Number:** 00779008414088 - **Manufacturer:** MG Chemicals ## Images ![4140A Flux Remover for PC Boards (Improved Formulation) 945 mL Liquid - Image 1](https://m.media-amazon.com/images/I/61-ct5xvKRL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Magic in a bottle - Move over IPA! *by T***Y on 6 November 2025* This works flawlessly.
