Professional Guide: Cleaning a Fabric Sofa Using BrightChem Upholstery & Fine Fabric Pre-Spray and WS Stain Repel Rinse

Cleaning delicate upholstery requires a careful, methodical approach to protect fibres while achieving a deep, residue-free clean. This guide outlines the recommended procedure for using BrightChem Upholstery & Fine Fabric Pre-Spray and WS Stain Repel Rinse on wool, viscose, and advanced synthetics.

1. Preparation

1. Assess the Fabric:

   • Confirm the sofa material is suitable for solvent-based cleaning: wool, viscose, or advanced synthetics.

   • Check manufacturer tags and look for cleaning codes (W = water, S = solvent, WS = water/solvent).

2. Vacuum Thoroughly:

   • Remove loose dirt, dust, and debris using a soft brush attachment.

   • Pay attention to seams, folds, and cushions.

3. Test a Hidden Area:

   • Apply a small amount of BrightChem Upholstery & Fine Fabric Pre-Spray to an inconspicuous area.

   • Wait 5–10 minutes to ensure there is no colour bleeding or fabric damage.

2. Mixing the Pre-Spray

Pump Sprayer:

• Standard soil: 30ml per litre of water

• Heavy soil: Up to 250ml per litre

Inline Sprayer:

• Standard soil: 1 litre per jug

• Heavy soil: 2 litres per jug

Tip: Use clean, cold water for dilution. BrightChem’s neutral pH 7 formula ensures safety for delicate fibres while providing effective grease and oil removal.

3. Application

1. Spray Evenly:

   • Apply BrightChem Upholstery & Fine Fabric Pre-Spray liberally in overlapping passes, ensuring complete coverage.

   • Avoid over-saturating cushions; keep the fabric damp, not soaked.

2. Allow Dwell Time:

   • Let the solution work for 5–10 minutes.

   • For stubborn areas, lightly agitate with a soft brush or microfibre pad to lift embedded soils.

4. Spot Cleaning (If Needed)

1. Prepare Spot Solution:

   • Mix 50% water and 50% BrightChem Upholstery & Fine Fabric Pre-Spray (1:1 ratio).

2. Apply to Stains:

   • Use a tamping brush or terry towel to gently work the solution into the spot.

   • Blot excess moisture and agitate lightly without rubbing aggressively.

3. Extract Residue:

   • Remove cleaning solution with a wet vacuum or extraction machine.

   • Repeat if stubborn stains persist.

5. Rinsing & Extraction

• After dwell time, rinse the area using clean water and a suitable upholstery extractor.

• For enhanced cleaning and protection, apply WS Stain Repel Rinse according to manufacturer instructions.

• Ensure thorough extraction to leave the fabric residue-free. BrightChem’s formula is designed for fast, clean rinsing, avoiding sticky deposits.

6. Optional Protection

• WS Stain Repel Rinse provides long-lasting stain and soil resistance while maintaining fabric softness.

• This is particularly recommended for high-traffic sofas or delicate fibres.

7. Drying

• Speed dry or allow the sofa to dry naturally.

• Ensure good airflow and avoid direct sunlight, which can fade delicate fibres.

• Fluff cushions periodically for even drying.
