ChemtronicsES835B Flux Remover, Brush, 5 fl.oz.

I have used this product for years on DIY Electronic kits and it works great to remove solder flux. Highly recommended!

Thank You!

Really not much to say here, flux remover removes flux. Brush head leaks a bit though.

Cleaned a 1978 circuit board nicely!

Product arrives without a spray cap- just the bottle, a brush, and a straw. I had to steal a spray cap from my WD40 spray can to use the product.

What more can you ask for. Cost is a bit high.

I was extremely pleasantly surprised with this product. It will clean any flux I could find and leave the board relatively spotless.Alas, nothing is perfect ... but this is pretty damn close!

The dispenser is made so 90% of the solvent goes on your hand as you grip the trigger. This is a monumental failure and does not even deserve one star. Totally unacceptable - I'm sending it back!Worst of all, this product does not dissolve or wash away flux from a PCB - it only spreads it around, making a huge mess. Is this a genuine flux solvent, or have they replaced it with some "environmentally friendly" but useless chemical? I tried using simple isopropyl alchahol and a small brush to finish the job, and I find it works much better that Flux-Off.Update: In response to email from vendor:If you read the reviews you'll find several other customers who have reported this same problem - why do you deny it? Also, if you simply tried using the product yourself you would understand that the brush attachment (required for applying solvent and scrubbing flux off the PCB ) fits loosely on the nozzle, and when the trigger is pulled it squirts solvent out of the back of the tube, which drips into your hand. 90% of the solvent goes on your hand and only 10% goes on the PCB. To correct the problem, you simply need to reduce the inner diameter of the brush attachment so it fits tightly around the nozzle.
