## Overview

The MG Chemicals 4140A Flux Remover is a 945 mL liquid solution designed for rapid, zero-residue cleaning of all flux types on PCBs. Its improved, plastic-safe formula aggressively removes rosin, non-rosin, no-clean, ionic, and non-ionic flux residues while complying with RoHS and food facility standards. Ideal for professionals and electronics enthusiasts seeking spotless, reliable circuit boards without harsh chemicals or lingering smells.

## Description

4140A FLUX REMOVER FOR PC BOARDS (Improved Formulation) cleans post solder residues quickly and conveniently. Its plastic safe formula removes rosin, non-rosin, and no clean fluxes, as well as both ionic and non-ionic residues. This product is used for spot cleaning flux while repairing or prototyping electronic circuits. Aggressive cleaning strength. ROHS Compliant. Read the product’s SDS before using it.

Review: 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: In my career, I'd used commercial/industrial flux remover available from my job. Now that I'm retired, my 'free' source was gone :-) but I wanted to continue to do electronics. Based on the MSDS sheet, this solvent is the closest to the commercial/industrial stuff, without the acetone. With no acetone, this flux remover is, in my experience, plastic-safe. If additional 'cutting' is required, I add a splash of acetone (nail polish remover) to get the job done. Very satisfied with the performance, easy to store, no objectionable smell, and inexpensive.
