Keeping your rolling tray clean is important. The resin from your cannabis buds can leave sticky areas on your rolling tray. These resin spots can foil your rolling endeavors by making your papers annoyingly sticky. You can clean this resin off with warm, soapy water. Gently scrub the tray with a sponge, but don’t press too hard. You don’t want to scratch the surface and potentially ruin the rolling tray’s design.
