How to Deep Clean a Sofa at Home: The Complete Step-by-Step Guide

Regular vacuuming and spot cleaning keep your sofa looking decent day to day — but every sofa needs a thorough deep clean a few times a year. Deep cleaning removes embedded dirt, allergens, bacteria, and odors that surface cleaning can't reach. This guide walks you through a complete deep clean for fabric, microfiber, and leather sofas at home.

What You'll Need

BISSELL Little Green Portable Carpet & Upholstery Cleaner — the most effective tool for deep cleaning sofas at home; extracts dirt and moisture from deep in the fabric
Resolve Multi-Fabric Cleaner & Upholstery Stain Remover — for pre-treating stains before deep cleaning
Rocco & Roxie Enzyme Stain & Odor Eliminator — for organic stains and embedded odors
Nutricost Baking Soda (2 lbs) — for deodorizing before and after cleaning
Amazon Basics Microfiber Cleaning Cloths (24-pack)
Pressurized Handheld Steam Cleaner — optional but excellent for sanitizing and refreshing fabric sofas
Vacuum with upholstery and crevice attachments

Before You Start: Check the Care Code

Find the care tag on your sofa and note the cleaning code:

W — Water-based cleaners safe (most fabric sofas)
S — Solvent-based only (use rubbing alcohol, not water)
W/S — Either method works
X — Vacuum only

This guide's wet cleaning steps apply to W and W/S coded sofas. For S-coded sofas, follow the dry cleaning steps only.

Step 1: Clear and Prep the Sofa

Remove all cushions, throws, and pillows. Check between and under cushions for lost items, crumbs, and debris. Move the sofa away from the wall if possible to access the back and sides.

Step 2: Vacuum Every Surface

Use the upholstery attachment to vacuum the entire sofa — seat, back, armrests, sides, and the sofa frame underneath the cushions. Switch to the crevice tool for seams and tight corners. This step removes the bulk of loose dirt, dust, and pet hair before any liquid is applied.

Step 3: Deodorize with Baking Soda

Sprinkle baking soda generously over all fabric surfaces — cushions, seat, back, and armrests. Let it sit for 20–30 minutes to absorb odors. Vacuum it all off thoroughly before proceeding to wet cleaning.

Step 4: Pre-Treat Stains

Identify all visible stains and treat them before the full clean:

For general stains: spray Resolve Fabric Cleaner directly on the stain, wait 2–3 minutes, blot with a microfiber cloth
For organic stains (pet urine, food, vomit): apply Rocco & Roxie Enzyme Cleaner, let sit 10–15 minutes, blot clean
For grease: sprinkle baking soda, let absorb for 15 minutes, vacuum off, then treat with dish soap

Step 5: Deep Clean with the BISSELL Little Green

The BISSELL Little Green is the most effective home tool for deep cleaning upholstery. It sprays cleaning solution into the fabric and simultaneously extracts the dirty water — pulling embedded dirt, allergens, and odors out of the fibers.

Fill the clean water tank with warm water and the recommended amount of BISSELL cleaning formula
Work in small sections, moving the tool slowly across the fabric
Overlap each pass slightly to ensure full coverage
Empty the dirty water tank as needed — you'll be surprised how much grime comes out
Do a final pass with clean water only to rinse the fabric

Step 6: Steam Clean (Optional but Recommended)

After extracting with the BISSELL, a pass with the handheld steam cleaner sanitizes the fabric by killing bacteria, dust mites, and allergens with high-temperature steam. Hold the steamer 2–3 inches from the fabric and move slowly. This step is especially valuable for households with allergies or pets.

Step 7: Clean the Cushion Covers

While the sofa frame dries, wash removable cushion covers according to their care labels — machine wash on gentle with cold water, or hand wash delicate covers. Air dry completely before replacing.

Step 8: Dry Thoroughly

Proper drying is critical to prevent mildew:

Open windows and doors to maximize airflow
Point a fan directly at the sofa
Stand cushions upright to allow air circulation on all sides
Allow at least 4–6 hours of drying time, or longer in humid conditions
Don't sit on the sofa until it's completely dry

Step 9: Final Vacuum and Brush

Once fully dry, give the sofa a final vacuum to lift any remaining residue and restore the fabric's texture. Use a soft-bristle brush to fluff the fibers back up for a fresh, like-new appearance.

Deep Cleaning a Leather Sofa

For leather sofas, skip the wet extraction steps. Instead:

Vacuum thoroughly with a soft brush attachment
Wipe down with a leather cleaner on a microfiber cloth, working in sections
Follow with a leather conditioner to restore moisture and prevent cracking
Buff with a dry cloth for a subtle sheen

How Often Should You Deep Clean Your Sofa?

Every 6 months for households without pets or children
Every 3–4 months for households with pets or young children
After any major spill or accident — don't wait for the scheduled clean

Pro Tips

Deep clean in the morning so the sofa has all day to dry before evening use
Work in sections and don't over-saturate — too much moisture is the enemy of upholstery
The dirty water in the BISSELL tank is a satisfying indicator of how much grime was hiding in your sofa
Apply a fabric protector spray after deep cleaning to repel future stains

Frequently Asked Questions

How long does it take for a sofa to dry after deep cleaning?

With good airflow and a fan, most sofas dry in 4–6 hours. In humid conditions or without airflow, it can take up to 12 hours. Never sit on a damp sofa — it can flatten the fabric and encourage mildew growth.

Can I use a carpet cleaner on my sofa?

Full-size carpet cleaners are generally too heavy and bulky for sofa cleaning. A portable upholstery cleaner like the BISSELL Little Green is specifically designed for furniture and gives much better results on sofas.

How do I know if my sofa needs a deep clean?

Signs it's time: visible staining, persistent odors even after spot cleaning, fabric that looks dull or gray despite regular vacuuming, or increased allergy symptoms at home. If you can't remember the last time you deep cleaned it, it's time.

Is professional sofa cleaning worth it?

Professional cleaning gives excellent results but costs $100–$300+ per session. With a BISSELL Little Green (a one-time investment), you can achieve comparable results at home and clean as often as needed. For heavily soiled sofas or very delicate fabrics, professional cleaning is worth considering.
