clean the cooling system

[sculptart@aol.com]

To all, What is the best way to clean the cooling system on the TC? I have looked into a lot of commercial products...is there one that is better than the rest or is there an "old fashioned way" to clean the system without the use of harsh chemicals? I seem to recall vinegar or something equally simple that would not harm the cooling components and seals. Thanks to all, Ben Cordsen
