I like marvy,and here's why. Both cost roughly the same,about $5.50 a pint at the local supply.Both use the same germicide , dimethyl benzyl ammonium chloride. But the marvy formula is 10% strength,barbicide is 5%,that means you get twice as much after dilution ! And that translates to "50% cheaper than barbicide".The marvy clearly states on it's label "safe for brushes"...barbicide does not.Mar-v-cide is a best buy in my budget book...
