I can't really throw any light on the above treatment, other than acetic acid would not be very friendly to bacteria :), but I don't really see any danger in "sealing infection in". Infection is dealt with internally by white cells, or antibiotics, in the blood stream the regular bathing should remove any pus or sloughyness and the cream would help prevent further bacteria entering through the broken skin. Ideally a wound or open skin area should be kept dry as bacteria like warm, wet conditions but thats not easily achieved with a paw so maybe a barrier cream is the way to go, just a theory anyway :)
