Ummm, most people use white vinegar, but I've found for extra stubborn verdigris, I use fresh lemon juice and a brass wire brush. Also, if it has lime build up, I also use a nut pick to gently scrape/chip off the crud: WARNING this needs to be done with a very delicate touch!!!!! Oh, and soak for about five-ish minutes... if you soak too long, you can really mess things up you didn't know were iffy Good luck, Jaybird

rf, I have a very old Dacor Olympic Regulators Maintenance & Repair manual from June 1, 1975. In it is this quote: I used the local drug store solution for several years, but ceased to do so when I moved, over 12 years ago. One of the reasons I have not gone back to this solution is the potassium dichromate is now classified as a "A1 Carcinogen" ("Confirmed Human Carcinogen") by the American Conference of Governmental Industrial Hygienists (ACGIH). Here's the Material Safety Data Sheet for Potassium Dichromate. Here is a more updated Safety Data Sheet following the Globally Harmonized Standard (GHS) for potassium dichromate. Brex Concentrate, according to its MSDS, is concentrated hydrochloric acid. Again, this has contact hazards, including an extreme eye hazard. I won't use it, as when it was used by Dacor it was in their repair department, and they had the controls (which should include a laboratory hood) to use it safely and the personal protective equipment (PPE: aprons, eye and face protection, nitril gloves, chemical sleeves, etc.). I am now simply using white vinegar. John

A 50/50 mix of white vinegar and water usually does the job. I prefer it over most other cleaners if for no other reason, it's basically a food stuff so getting it on or in you is not a problem. Vinegar will attack chrome if it's weakly plated or if you over soak it. Usually a few minutes is enough and an ultrasonic cleaner helps a lot.
