We have pressuirized double shot filter, but we don't know how to clean it.
Unfortunately all written instructions in Russia are about Commercial filters, although pressuirized are also sold. So we can't find information how to clean it. Local sellers also can't answer us.
We mean everyday cleaning. While it is double shot and has two bottoms, there is a chance for mold to start there of simply grime. According to our law we have one week for testing goods and returning it back (in fact, two weeks, but one has already passed) if we are not satisfied with it. We would have to take commercial or simgle shot filter then because we can't clean our filter properly, unfortunately, though we like double shot the best! It would be sad.
