After ensuring your CARTA 2 is turned off, first remove the glass top, then detach the Intelli-Core MAX atomizer from the base of the unit.
Next, remove the silicone carb cap sleeve from the atomizer. Submerge both the atomizer and the cap's D-PAD in a dish or container filled with isopropyl alcohol and let them soak for at least ten minutes, or until all residue is removed.
While the atomizer and D-PAD soak, gently clean the bottom of the silicone carb cap sleeve using a 70% isopropyl wipe. Ensure to quickly wipe off any remaining isopropyl with a dry paper towel. Then, remove the atomizer and D-PAD, and allow both to air dry completely before proceeding. This may take anywhere between one and two hours.
Once the atomizer and D-PAD are completely dry, insert the D-PAD into the silicone carb cap sleeve, and then reattach the silicone carb cap sleeve onto the MAX atomizer. Next, secure the atomizer back onto the CARTA TWO base.
After this, replace the glass top onto the CARTA 2 base, and you're all set!
