Gifted A MOMET - Advice Pls

[jeffg]

Hi,
My M-I-L gave me a MOMET moisture meter (wish I got a gift cert to Nasser's, oh well...). Anyway, I was curious about the thing - how it might aid in the watering regime, then concerned about pushing the probe from plant to plant - potentially sharing media problems.

I wrote the company with my sterilization concern and here is their reply: "Most people do not sterilize between plants. You can just wipe the probes clean of soil with a wet cloth. One of the owners has an orchid retail operation and never sterilizes the probes while checking thousands of plants." Richard Duin JERMIC, LLC

Does this sound like appropriate hygiene?

I'm sticking with letting the plant inform me of when it needs water for now, but thought I'd check it out with ya'll.
