I Removed a old box that was screwed into my baseboard in my dinning room. It looked to be the original doorbell to the house, I unscrewed it from the wall and cut the wires. Two days later my wife tells me that the doorbell isn't working. Could this old doorbell have been still connected to the new one. And when the wires was cut it broke the circuit.
Chances are very good that the new doorbell uses the old wires and you killed the doorbell by cutting the wires.
It is not common for doorbell components or accessories to be mounted low down on the wall such as on a baseboard.
When cleaning anything including baby diapers, it is better to sweep off or scrape off as much solid and semisolid material as you can first. (1) Less cleaning fluid or detergent needs to be used, (2) Less of a mushy mess which in turn means that bleaches or disinfectants will be more effective.
