03QuestionsBefore you order

Before you order.

Straight answers. Anything else, email support@thinkcrucial.com.

Q.01What is white dust?

Mineral scale off the ultrasonic transducer, blown into the room with the mist. Wiping the tank doesn't fix it because the film is on the transducer.

Q.02How many descales per bottle?

15 per 8 oz bottle.

Q.03Is this the same as humidifier drops?

No. Drops are a conditioner added at every refill. This is a soak that removes scale already formed.

Q.04What if it doesn't work with my machine?

If it doesn't work with the machine we list, email support@thinkcrucial.com and we'll refund it. You don't need to send it back. Unopened bottles can also be returned within 30 days of delivery.

Q.05Is there a subscription?

No. You buy when you need it. Nothing renews and nothing auto-ships.

Q.06When will it arrive?

Free U.S. shipping on every order, from a U.S. warehouse. Ships the same business day when ordered by 2pm ET. Arrives in 2–5 business days.

04Who makes this
