Moving into a new apartment raises concerns about cleanliness, especially when previous tenants may have left behind issues like foot or nail fungus. For effective carpet sanitization, renting a carpet cleaner from a local grocery store is a cost-effective option, typically available for around $15. Steam cleaning is recommended, particularly with sanitizing formulas, especially if the carpet is synthetic, which is less delicate than wool. Some participants suggest using boric acid or borax, both known antifungal agents, while emphasizing safety precautions like wearing a mask and protective clothing during application. It's also crucial to check for colorfastness before applying any cleaning solutions. Overall, thorough cleaning is essential for maintaining a healthy living environment.
