MrBW on "Remove a filter....."

I need to disable this filter:
$message = apply_filters( 'woocommerce_mail_content', $this->style_inline( $message ) );

The style_inline() function exist in a class called WC_Email. So I tried:
remove_filter("woocommerce_mail_content", WC()->WC_Email->style_inline());

But it was a wild guess and it didn't work.
