This is a good product...I take a tiny amount and put it in a mayo jar with water...then after dilution I pour it onto my scrubber sponge (the ultra thin ones that are a little abrasive...green colored). I use it while I have the VERY warm water running under the faucet, and rinse the egg off, cleaning one egg at a time. It gets the eggs cleaner than with just water, which I like since we hard boil eggs sometimes. The eggs that crack open during the boiling process make me want the eggs clean to begin with so we can eat them. It will last a very long time if you dilute it as recommended. It is very concentrated.
