pretty much useless
I have used the L Letterpress cleaning wipes and they worked really well but are expensive, get used up quickly, and are hard to find. So I got this spray thinking it would last longer. You are supposed to spray and let sit for 3-5 minutes then wipe or scrub away. Well I tried waiting as long as 10 minutes and even wiping right away but this spray hardly cleans. It's only slightly better than buffing off the ink with a plain paper towel. Stick with Goo Gone or vegetable oil.
