The general rule of thumb is don’t use the first 3 or last 3 sheets of paper towels for Pesach because they contain glue. Many Posekim recommend to their kehillas that they don’t use R’Blumencrantz’s Pesach guide because of chumrahs such as the one you refer to.
But don’t worry about it, it’s almost a year till next Pesach, by which time there’s sure to be new and exciting chumrahs to deal with.
