Some glass cleaners also sanitize surfaces by killing bacteria and viruses. To confirm, thoroughly read through the ingredients listed on the packaging, or refer to the product page on the brand's website. Katie Berry, The Spruce's Cleaning Review Board member, notes that products with ammonia or alcohol have sanitizing abilities. "Plant-based glass cleaners do not contain these and are not suitable for sanitizing." If you use glass cleaner to sanitize any area that is used for food preparation or cooking, make sure to rinse the surface well.
