After ordering your Starter Kit + Refill Plan, you'll receive Refill Kits after 45 days that includes 4 refill cartridges for each cleaner. We’ll send Refill Kits every 6 months after that, 'til death do us part. (Or, you know, until you change your delivery schedule.) Overachievers can order more refills anytime on our store or by text: 415-TRUMANS (878-6267). You can also pause your subscription if you’re a slob.
