A clean upholstery makes a bigger difference than you'd think. Here's the most effective method, plus the mistakes most people make.
Vacuum all surfaces and crevices with the upholstery attachment. Remove cushions and vacuum underneath.
Find the tag: W = water safe, S = solvent only, WS = either, X = professional only.
For W-coded fabric, spray Vibes Multi-Surface Cleaner on a cloth and blot stains. For S-coded, use rubbing alcohol.
Sprinkle baking soda over the upholstery, wait 20-30 minutes, then vacuum off. This absorbs odors and refreshes the fabric.
