What Carpet Cleaning Is Best

The best carpet cleaning method depends on soil level, carpet type, drying time needs, and whether you're doing DIY or professional service. Hot water extraction (often called steam cleaning) ranks as the top choice overall for deep cleaning embedded dirt, allergens, and stains while meeting most manufacturers' recommendations.

Main Cleaning Methods Compared

Each technique has trade-offs; hot water extraction excels for thoroughness, but low-moisture options suit quick refreshes.

When to Choose Each

Opt for hot water extraction every 12-18 months professionally—it's IICRC-recommended and restores fibers best. Use dry or bonnet for weekly upkeep or delicate wool. In humid climates like Salt Lake City, prioritize low-moisture methods to avoid mildew.

Pro Tips for Success

Pre-vacuum thoroughly and treat spots first for any method. Professionals add pH balancing to prevent residue. Pair with HEPA filtration for allergy relief, and maintain by vacuuming weekly.
