I'm looking for a reliable cleaner to wash a wall in my kitchen. The wall has some grease stains from cooking and a few marks from kids' artwork. I need thorough wall washing, spot treating stubborn stains, and a fresh overall wipe-down. Please bring appropriate cleaning solutions safe for painted walls and wear shoe covers if needed. Flexible on timing, but prefer a morning slot. Residential cleaning in a non-smoking home. Happy to discuss square footage and any prep I should do beforehand.
