pump maintenance

[fiorano]

So i was cleaning my bubble king the other day and in the hilariously translated instructions it said not to wash the pump with acetic acid. isnt acetic acid basically vinegar? now i didnt want to wreck my pump and it was late so it just cleaned with a brush and water but i have always washed all of my other pumps by running them through in a bucket of straight vinegar. Also the pilot bearing doesnt come out of the pump like it is supposed to. does anyone else have a bubble king and would share there maintenance schedule. Thank you! it is a bk mini 180
