Winsol Solar Brite (5 gallon pail)
The Winsol Solar Brite 5 gallon pail is a professional quantity of the same mild-pH concentrate as the gallon: about 165 gallons of solution at the light-duty 1:32 dilution, sized for a crew's quarterly supply, not a homeowner.

Who should skip this
Skip it unless you clean for a living; five gallons of concentrate is a crew's stock. Homeowners should buy the gallon, or the quart Winsol also sells. It is the same soap as the gallon row, so the dilutions are identical.
