For those burnt on and hard to get off stains, I recommend using Bar Keepers Friend – Soft Cleanser. This effective cleaner is safe to use on stainless steel, ceramic, tile, copper, & porcelain! Use it on cookware and other places in the kitchen (or bathroom) to remove rust, lime, stains, & tarnish!

Note: Bar Keepers Friend is NOT safe to use on plastic and should not be used to clean your Thermomix base, lid, measuring cup, and other non-metal parts & accessories.
