Cleaning the fluidic path

[ilyphotocip]

Hello,
I want to ask you if I could cleaning the fluidic path with ACETONE to a GPC system by Waters with refractive index detector 2414.The reason for I ask you, is that I make an analysis of copolymer styrene-acrylonitrile with a big molecular weight (the system is dirty now)and the common solvent to cleaning the system is acetone.Could I used to my system without damage the GPC?
Thank you
