Hi,
Have just took a mid morning reading of 20, but have felt like it could be lower. I remember reading somewhere that certain hand soaps could contain glycerine and other products that could affect a reading.
I’ve narrowed down to the soap I use in my house, and would like to know what alternatives people use, liquid or bar etc?
Thanks
Darion.
