RE: Carbon Blast?
I agree w/ SW - the closer you hold the bottle to your clothes - the backer it gets. If you hold it 8-10 inches away it' s not bad. I haven' t used it much but after it dried - i didn' t notice the black as much and it washed out too.
The one problem I had was that the " squirter" gets blocked up w/ carbon molecules. I ended up pouring it into another container so that I could keep using it.
Haven' t decided yet if i' ll use it this year or not.
