After posting about Vinegar and Mustard (Both Mustard & Straight Vinegar INDEED etch stainless..perfectly! See ya Ceramark) etching steel we made a rather amusing discovery. Seems my use of the paper towel was actually more of a discovery than the acids. Thanks to @jgf making the simple attempt to use a plain water soaked paper towel as a control, he found that the results were JUST as good as with vinegar… no acid needed! I guess it prohibits the reflection and maybe the moisture helps… Anyone way smarter than me able to speak to this?
I tried it and it is true… I actually think it might even be crisper than with the vinegar if even a tap lighter!!
Maybe because there are no fumes trapped under the towel! I also tried it to make sure it wouldn’t etch directly with nothing… it does but it is VERY light and spotty even with multiple passes.
If it is properly wet (really damp not dripping or anything) you won’t need to attach it… the water seemed to hold it on fine in this instance. The water does dry super fast where the vinegar didn’t.
This is on speed 250 on Full Power 320lpi!
