Came across 2 / 1 Gallon Jugs of Liquid Laundry Detergent.. One of those forgotten purchases shoved to the back of the shelf.. My guess , it was a deal that couldn't be passed up.. by the way they were left behind by the Previous Home Owner.. lol..
My Query is 2 Part , How to determine if it's a concentrated blend and if so what would be a safe measurement?
