Buying Guide
What should I look for in carpet cleaner fluid?
- Compatibility: Ensure the fluid is designed for your carpet cleaning machine model or type (upright, extractor, or portable).
- Tough stain performance: If you have set-in stains or pet messes, choose formulas that emphasize stain removal and odor control.
- Concentration vs. dilution: Concentrates save money but require accurate dilution per your machine’s guidelines to avoid residue.
Pet owners or households with odors—what works best?
- Look for Odor Elimination and Odor Neutralizing features, such as Oxy-based or Febreze-enhanced formulas.
