A stainless steel dishwasher interior is generally considered better than a plastic interior for several reasons:
Durability: Stainless steel is more durable than plastic, and is less likely to crack, dent, or warp over time. This means that a stainless steel interior is likely to last longer and require fewer repairs or replacements than a plastic interior.
Resistance to Stains and Odors: Stainless steel is less likely to absorb stains and odors than plastic, which can be important for maintaining a clean and hygienic dishwasher. Plastic interiors can absorb stains from certain foods and beverages, which can be difficult to remove and can leave an unpleasant odor.
Heat Resistance: Stainless steel can withstand higher temperatures than plastic, which is important for a dishwasher as it operates at high temperatures to clean dishes. This means that a stainless steel interior is less likely to warp or melt under high temperatures, which can affect the dishwasher's performance.
Aesthetics: Stainless steel is generally considered more aesthetically pleasing than plastic, and can give a dishwasher a more high-end and modern look. This can be an important consideration for homeowners who value the appearance of their appliances.
Overall, a stainless steel dishwasher interior is generally considered to be a better option than a plastic interior due to its durability, resistance to stains and odors, heat resistance, and aesthetic appeal.
