The carafe is usually made of tempered glass, making it pretty delicate. Some are made out of stainless steel. Here are some things to not do\u00a0when cleaning your French press:Never use harsh cleaners. Never use cleaners like Comet or bleach to clean any parts of your French press. This will not only leave a nasty chemical flavor behind, but that flavor is nasty for a reason. These chemicals aren’t meant for use on food preparation surfaces because they’re incredibly toxic. Not only that, they can shorten the life of your French press.Don’t leave coffee grounds in your French press. You should always be emptying the coffee and the grounds from your French press. Hopefully, you’re cleaning it after every use as well.

Some sites are touting this approach, but it can weaken the glass carafe or scratch the carafe.
