Caig Labs CL-ETCH-16 Ferric Chloride PCB Etchant Solution 16oz Bottle

I used it to etch a makers mark on the side of steel knife blades, and it works very well when used with a adhesive vinyl mask, which I cut on a silhouette cutting machine

Used it to etch a meteorite. Worked very well, seems very strong. Baking soda took a while to neutralize the left over waste. Also came very well packaged and sealed in a separate bag.

It etches damascus steel easily.

Good

works very good for etching knives. that's what i use it for.

This etches metal great, but not a good refill for the etch-a-sketch.

After some use it just stopped working. Maybe I'm the problem. Prab. Will be doing some research.

This is a great product for etching your own printed circuit boards. I've used this product before but from a different supplier & they no longer carry this size so I was pleased to find it here. It was well packaged for shipping & inside, the bottle had a sealed plastic bag for any leak protection.
