If you are as ham-fisted as me when stamping onto acetate you will need this one!
Staz-on cleaner will remove smudges of Staz-on ink from acetate - yes even the next day - and big areas. Use a cotton bud to tidy small areas and a make-up pad on large areas. If you want to clean off a big mess, hold the pad for a few seconds to let the cleaner start breaking up the ink.
And - yes it does completely clean the acetate so you can have another go!!
Ps you can also use staz-on cleaner to wipe your knife / scissor blades and clean them
