Don't push dust and particles aside when you can remove them – cleanly! This innovative cleaning system captures dust and particles directly from your sign substrate without scratching or leaving static behind. Power Cleaner is literally a space age technology, developed for use in space technology clean rooms and bio-medical research labs, where an absolutely dust- and particle-free environment is of the utmost importance – just as it is with sign-making applications, where it's critical that your vinyl is applied on a completely clean and particle-free surface. By working closely with our partner, we're now able to bring you this advanced cleaning system at the most affordable price ever. Here's how it works: Simply roll the Power Cleaner slowly and steadily over the surface in a single direction. The special rubber-like roller material captures all the dust particles securely. Remove the protective paper from the roller-cleaning sheet Roll the dirty roller from the top, downward on the viscous roller-cleaning sheet The particles are then safely captured and cannot be transferred back to your substrate.
