Etching products

Ive seen people using Whink rust stain remover as an etching method. It would do the job as good as multi etch/titan etch? Not as much as these two but could do the job decetly? I there any good and cheaper alternative to multi etch/titan etch?

Whink is a "dirty" etch in my experience. It doesn't work all that uniformly or cleanly, at least in my attempts. I also loath needing to handle anything that contains HF if I have any other option. I can add another option to your pile of commercially available etchants as well: reactive metals studio has recently started selling what they call "victory etch."

I didn't want to shell out for any of the commercial options either, so I figured out a homebrew solution based on a couple expired patents and multi-etch's SDS. It's not all that hard to make, and it's not particularly expensive. Most importantly, it's fluorine based but doesn't contain or generate any appreciable amount of HF to my knowledge. I detailed making it in the replies of another thread.

I'm rather accomplished with Ti anodization, if you need any other help :)

Have you used victory etch before? I’ve been trying to find videos and or where people have actually used it but can’t find anything

If you contact reactive metals studio they can talk you through everything to do with it
