Since the inception of 5S and other lean elements (communication) using whiteboards and dry erase surfaces, we have invented a few documents using laminated sheets.
While very usable, the plastic is just porous enough that after a few months of use, the surface is difficult to clean.

I am doing another batch of these custom dry erase documents, and before I do, I am looking to improve this, if possible. Does any one know of a brand of laminate sheets to use with a hot laminate machine that are more appropriate to my needs? We need standard 8 1/2 x 11 and 8 1/2 x 14 sizes only.
Any one else doing something like this?

The recommendation of wet markers has come up, but it is just not practical for us.

FWIW:
I use a mild glass cleaner spray (generic) at the end of each session on a whiteboard, wiped with a soft cloth, not harsh paper towels which can scratch the surface of the whiteboard. Usually, it is the scratches in the surface, not the pores in the plastic, which hold the dry erase pigments.

I often did markups in both dry erase and so-called "permanent" markers on laminated drawings. To clean, I used glass cleaner for dry erase and 70% propyl alcohol (rubbing alcohol) to erase the permanent marker. Using the same drawings for years as teaching tools, I never encountered "burn in."

I imagine engineers who deal with mylar drawing media have a whole regimen for dealing with drawing and erasing permanent and dry erase markers.

Another hint to remove permanant marker from 're-writable' surfaces is to go over the permanant marker with erasable marker. Something in the ink acts as a solvent. I agree with the soft rag vs. paper towell. It keeps the surface smoother.

As I said prior, wet is not practical at our work stations.

Seems there is no one manufacturing such an item. I did find a pro laminate that is better, but it is for large scale.
The future may be custom whiteboards instead.

They are damp, not wet and can be disposed of in a regular wastebasket. They come in a waterproof plastic container and dispense one-at-a-time.
