Used Barnacle Buster, works great! Di it with a 5 gal pail and a few 3/4 inch hoses to circulate with a small high volume pump. Really cleaned the cooling fins, etc. I took them apart to check and changed impellers afterwards. BB is a solution of muratic acid according to MSDS. Used that the next time and it worked just as good IMHO. Used that to clean AC hoses.
Noticed no problems. HTH
