## Overview

MG Chemicals 4140A Flux Remover is a high-performance, zero-residue cleaning solution designed for post-solder flux removal on PCBs. Its plastic-safe, RoHS-compliant formula effectively eliminates rosin, non-rosin, no-clean, ionic, and non-ionic residues, making it ideal for industrial, prototyping, and food facility applications. Packaged in a convenient 1-quart bottle, it delivers professional-grade cleaning power with minimal odor and maximum safety.

## 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: 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.
Review: Very Close To Commercial/Industrial Solvent Without The Downsides - 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.

### ⭐⭐⭐⭐⭐ Ain't the cheapest, But it really works well.
*by M***N on September 16, 2023*

I wiped flux all over a controller board and used a paper towel to wipe off what I could, then I used IPA 91% and kimtech wipes and it came off super clean. Then I poured some into a small plastic kitchen container I bought for my ultrasonic machine, and it came out great. Had a bit of a shine to it, so I tested and there was a film, I put it in a rinse bath of warm distilled water and it looked like a brand new board.
