If you get this type of battlemat, just remember to use washable markers, like /u/pcx226 said, or get Staedler non-permanent markers, link below. Never use dry-erase markers because the material is too porous and will be incredibly difficult to clean off. With washable markers and map markers, all you need is to use water and a clean towel. If you leave the drawing on for too long, over a week or so, you will need to clean it with rubbing alcohol, but repeated use of rubbing alcohol will eventually remove the printed lines.

Can confirm. The laminated scratch pad was basically identical to this one from Amazon but white instead of yellow and without Manhattan branding. I also wanted to practice with the actual marker. Here’s the link: https://www.amazon.com/dp/B0007OEDOI/ref=cm_sw_r_cp_awdb_imm_G83VD96D8PB2HNJTGPSH?_encoding=UTF8&psc=1

Is this overboard? Maybe, but I enjoyed practicing my scratch work with the exact setup. I highly recoupment getting the wet erase, fine tip marker.
