I've seen directions on how to make a general pH probe cleaning solution:
"General Cleaning: Soak the electrode in 1:10 dilution of household laundry bleach in a 0.1 to 0.5% liquid detergent solution in hot water with vigorous stirring for 15 minutes. Place junction under warm, running tap water for 15 seconds. Drain/refill the reference chamber. Soak the electrode in storage solution for at least 10 minutes."
I get how to make 1:10 dilution of bleach BUT how would one make a 0.1 to 0.5% liquid detergent solution?
Is this a good general pH probe cleaning solution? Are there better ones?
