My hydro dealer told me to clean with Hydrogen Peroxide. Store in water. I bought the Milwaukee probe that always stays in the resevoir -I love it.:hippy:
avon211 Reviewed by avon211 on . How do you store/clean your ph pen? Ive noticed some small stuff stuck up in my pen so I need a good safe way to clean it. I was reading some things and am now curious about how everyone stores their pens. I need to find a good way. Rating: 5
