How can I remove residue from the SPIN 90 / 120 burner cup?

The remaining residue is primarily starch, which serves to thicken the bioethanol gel for SPIN 90 / 120—these models use gel for enhanced safety instead of liquid fuel. This residue does not impact the burner’s performance or flame quality, and a perfectly clean surface is not required. To clean, you can use any of the following methods:

– Hot water with dish soap and a splash of vinegar essence

– Hot water with half of a dishwasher tablet

– Hot water combined with baking soda and vinegar essence

Let the mixture soak for several hours, then rinse thoroughly. Stubborn residue can be removed with a pot scrubber, such as steel wool. Alternatively, the burner cup is dishwasher-safe and can be washed after each use.
