"cleaning tasks" → sanitation jobs

"Creating a healthier environment for you and your family." Producing A more hygienic setting Benefitting Your loved ones.

Starting with the first sentence: "Professional housekeepers use specialized equipment and cleaning products to eliminate germs, bacteria, and viruses, creating a healthier environment for you and your family."

"Professional housekeepers" – the proper noun here is "Professional housekeepers" but maybe just "housekeepers" is the proper noun? Wait, the user said "Proper nouns stay." So if "Professional housekeepers" is a proper noun (like a trademarked term), we need to leave it. But in general, it's a common noun. Hmm. Maybe the user wants to leave any proper nouns like brand names or titles. Let me check the example text again. There are no capitalized words except Housekeeping Services and the types listed, like "One-time deep cleaning," but those are headings. The user says "Proper nouns stay," so maybe they are referring to terms that are specifically named, but in the example, most are common nouns. I'll proceed to replace all words unless they are proper nouns. Since the example doesn't have specific proper nouns beyond the types of services listed, which are common nouns, I'll replace them all.
