Using a Superautomatic Espresso Machine on Pesach

Hi,

I have a superautomatic espresso machine like the one in the below photo. It has a plastic milk frothing job (that can be detached). The machine has occasionally been used to froth oat milk in the past. Can I use the espresso components and/or the milk jug on Pesach? If so, what do I need to do to ensure it is ok to use?

Just clean well and dont use oat milk in the frother within 24 hours of the day before pesach (this year Thursday).

Thank you!
