I never use wipes - too much single use landfill filler.
I have heard that the ambulance service do not use alcohol wipes before taking blood sugar readings because the alcohol can affect the readings.
On hearing this, I went from "not at the moment" to "never"
I got cracked hands when first diagnosed as I was constantly washing them before testing. Now I just test and then wash and test again if the result seems too high or too low given the circumstances.
