If you’re using a rotary cutter to slice through anything that’s adhesive-backed, there’s a good chance the adhesive will gum up your cutter. It happened to me this weekend and wreaked havoc on the project and my hands (not to mention how incredibly unsafe it is).
The good news is: this was a quick and easy fix. A quick dusting of WD-40, a run across the cutting surface, and a thorough wipedown not only cleaned the gunk that was there; it slowed the accumulation of new gunk!
Stay safe and cut well – a little WD-40 on your rotary cutter goes a long way!
