The benefits of a stainless steel thermal mug are durability, effective insulation and ease of cleaning. Stainless steel thermal mugs last longer than ceramic or plastic thermal mugs, and they are resistant to breakage. Stainless steel is also easier to clean and is resistant to corrosion from tough cleansers.
Upon cleaning, stainless steel thermal mugs rarely retain the smells and flavors of the beverages that have been in them. Often, stainless steel mugs use vacuum insulation to keep beverages hot or cold; this works better than the air or foam insulation that is used in ceramic and plastic thermal mugs. Stainless steel thermal mugs give better value for money.
