I thought I'd share a tip I have on the cleaning of stainless steal surfaces. I installed a stainless steal cooker and extractor hood in my kitchen last year and I have been surprised by the number of people that wanted to know how I kept it clean and without smudging, smears or water marks. Once you clean the surface, usually with warm soapy solution, apply a small amount of mineral oil to the surface, you will find not only does this give a very good finish but the oil also acts as an additional cleaner and will remove any remaining oil/fat splashes.
