This is not a washing machine; if you have blue heating degreasing, abandon all hope! This is an interesting device especially when other cleaning options are ineffective: for example hearing aids (not the amp section, I hope you guessed it); jewelry, metal bracelets, glasses ... the list is not closed ... This does not forbid you to give him other small objects that will clean well enough if you give it some time: it is adjustable up to 7 minutes 30. Its price is affordable.
