## Overview

MG Chemicals 4140 Flux Remover is a 400g aerosol solvent blend designed for effective cleaning of rosin, non-rosin, and no-clean fluxes on PCBs. Its non-corrosive, non-conductive formula is safe for plastics and sensitive electronic components, featuring a balanced evaporation rate for optimal cleaning performance in professional electronics maintenance.

## Description

The 4140 Flux Remover for PC Boards is a blend of ethyl alcohol, isopropanol, and ethyl acetate that is an dry cleaning solvent. It has a non-corrosive and non-conductive formulation with a moderate dry time.Since the 4140 is safe for most plastics and printed circuit board components, it is used heavily in the electronics industry. It is great for removing rosin, non-rosin, no-clean fluxes, and ionic contamination.

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: Works, a little expensive - Works well. Better than using alcohol. Kind of expensive for 32oz.

Works well. Better than using alcohol. Kind of expensive for 32oz.

### ⭐⭐⭐⭐⭐ Very Close To Commercial/Industrial Solvent Without The Downsides
*by D***W on May 11, 2025*

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.
