What method can help to remove dirt and oils from a thermal iron?

Using a damp soapy solution is an effective method for removing dirt and oils from a thermal iron because the soap helps to break down oils and grime, making it easier to clean the surface. The dampness of the solution allows for easy application without saturating the iron, which could potentially damage it or create safety hazards. This method ensures that residues are lifted away without leaving behind moisture that could cause rust or electrical issues.

In contrast, using vinegar could potentially help due to its acidic properties, but it is not the best choice for a thermal iron as the acidity could affect certain finishes. Wiping with water alone lacks the cleaning power needed to effectively remove stubborn oils and dirt, as water does not emulsify or break down oil effectively. Utilizing oil would only add to the problem, making surfaces more slippery and grime-encrusted, rather than cleaning them. Therefore, a damp soapy solution is the most effective and safest option for maintaining the cleanliness of a thermal iron.
