I picked up a 10 liter cole-parmer ultrasonic cleaner on ebay last week. no heater but works fine. using a mixture of simple green and water. below are some before and after pics of a weber top. also trying a well-carboned head which is much slower but it's getting there. you can't use solvent in it directly but apparently you can put a glass container in the unit containing solvent to clean injectors and such.
observations -
1. sometimes a slow process but requires absolutely no effort on my part
2. cleans things very well
3. removes corrosion from aluminum but won't look 'new' again, discoloration is still there
4. you can put your hands in the cleaner no problem, but if you have an open cut - you'll know about it.
questions-
1. what solution are other guys using? barring commercial types, they're a pain to get here.
2. will part orientation in the tank have any affect on the cleaning of a particular area?
3. any other experience/tips?
before and after, about 3 hours worth.
