Whether or not a cleaner brings supplies also depends on their preference. Some cleaning services require the homeowner to supply cleaning products and a few basic materials (sponges, paper towels, rags, a mop, and vacuum, for example), but others bring everything they need to get in, clean, and get out. You can always ask whether or not they bring their cleaning supplies, and if so, make sure you’re comfortable with what they use. If you prefer organic or natural products, for example, you may need to supply them or pay a premium.
