Frequently Asked Questions

How often should this deep cleaning process be performed on kitchen and bathroom floors?

The frequency of deep cleaning depends entirely on foot traffic and how well the surfaces are maintained on a weekly basis. High-traffic areas like kitchens and mudrooms generally require an intensive scrub every few months, whereas guest bathrooms might only need this level of attention once a year. Regular sweeping and routine damp mopping will significantly reduce the accumulation of deep-seated grime, lengthening the time between intensive cleaning sessions.
