If you are interested in MAKING your own mats- please read my post, Make Your Own Mat for Cricut, Silhouette and Other Die Cutting Machines
I am writing this post up because it is one question I get asked all the time- How to refresh a tired un-sticky Mat.
If your mat is a bit dirty I recommend using baby wipes. Give the mat a good wipe down with your Baby wipe (I like Huggies or Kirkland/Costco brand). Why Baby wipes and not just paper towel and soap? Because the wipes have a touch of oil in them which help clean off the gunk. Wiping a relatively clean mat with not only clean it but revive the “sticky” Try it- you’ll be amazed!
If your mat is embarrassingly bad like mine – you would be shocked at the state I let my mats get into- there will never be glamorous photoshoots of my craft area- I can tell you that :-)– You have to step things up a bit.
I give mine a gentle scrub with a scotch brand dish sponge- the gentler one. You can pretty much use any cloth with a bit of grit to it- but NOT SOS pad or metal scrubber- you will tear or rip mat. Use a tiny bit of dish soap. The scrubber with lift-off gunk and you may also want to use a palette knife for stubborn stuff.
I have had some luck with “sticky” staying if it newer mat- bit Honestly a few shots of Repositionable Spray Adhesive and you are good to go!
Hope this helps you extend the life of your Cutting Mats!
