Once you go De-solv-it, you never go back. Seriously, baby oil sucks now that I've used that.
I've taken it to the last two contests and many competitors have used it, liked it, and asked where they could get it.
And here in AZ we train stones outside in dirt (with mats) and always getting gravel and bits of rock stuck on our hands, which makes it harder to clean up. I had to find something that worked well.
