Cleaning — FAQ
Is it safe to use a pressure washer in my living room?
Only electric models under 2500 PSI with proper ventilation and water containment are safe for indoor use. Always test on inconspicuous areas first, use the widest nozzle angle, and never spray directly at electrical outlets or baseboards. Gas models are extremely dangerous indoors due to carbon monoxide.
What PSI is safe for cleaning indoor furniture?
For upholstery and delicate fabrics, stay below 1500 PSI. Sealed hardwood and tile can handle 2000-2500 PSI. Always start with the lowest pressure setting and increase gradually while monitoring for surface damage. Antique furniture requires under 1000 PSI.
How do I prevent water damage when pressure washing indoors?
Use plastic sheeting to protect walls and floors, work in small 4×4 foot sections, and keep a wet vacuum nearby. Choose models with 1.76 GPM or lower flow rates, and avoid spraying toward electronics, vents, or unfinished surfaces. Allow 24-hour drying time.
Are electric pressure washers quieter than gas for indoor use?
Electric models are dramatically quieter—typically 70-80 dB versus 95+ dB for gas. Induction and brushless motors are the quietest options, running at conversational volume levels. This makes them suitable for apartments where noise ordinances apply.
What nozzle should I use for cleaning upholstery?
Always use a 40-degree white nozzle or soap nozzle for fabrics. Hold the wand at least 18 inches away and use a sweeping motion. Test on a hidden area first, and never use 0-degree or 15-degree nozzles as they will tear fabric and cause permanent damage.
Can I use cleaning solutions in my pressure washer for furniture?
Yes, but only use detergents formulated for pressure washers and safe for your furniture material. The onboard soap tanks in these Westinghouse models automatically dilute solutions. Rinse thoroughly with clean water to prevent residue buildup that attracts dirt.
