Question about Honeywell HM509H8908 Humidifier
You could add an inline water supply filter. That would help some, since it appears you have a hard water situation. A 50/50 solution of white vinegar and water will clean the existing lime scale. Adding a whole house water softener is also a good solution.
Hope this helps solve your problem.

Try white vinegar instead. The same type of scale builds
up in drip coffee makers. Most recommend white vinegar to remove the scale that
builds up over time. The added bonus is it costs less and is completely safe. If your unit is a water over paper media humidifier, you would be much easier to replace the paper media.
