Cleaning — FAQ
Is it safe to use a pressure washer in a bathroom?
Yes, with proper precautions. Use cordless or GFCI-protected electric models under 2500 PSI. Never spray directly at fixtures, grout lines, or wall corners at close range. Keep the unit outside the bathroom when possible and wear rubber-soled shoes to prevent slips.
What PSI is safe for cleaning bathroom tiles?
1500-2000 PSI is ideal for most bathroom surfaces. This range removes soap scum and mildew without damaging grout or forcing water behind tiles. Start at 1200 PSI and test in an inconspicuous area, increasing gradually only if needed.
Should I choose cordless or corded for bathroom cleaning?
Cordless is safer and more maneuverable for bathrooms. Corded units require GFCI outlets and careful cord management to avoid electrocution. Cordless models eliminate tripping hazards and let you clean behind fixtures without unplugging.
Can pressure washers damage bathroom grout?
High PSI above 3000 can erode grout over time. Use a 15-degree nozzle minimum, keep the wand 12 inches from surfaces, and avoid prolonged spraying on single grout lines. Seal grout annually to protect against water intrusion.
How do I prevent water damage when pressure washing indoors?
Seal doorways with towels, cover electrical outlets, and ensure floor drains are clear. Use the lowest effective PSI and GPM. Work in sections and squeegee water toward drains immediately. Never spray upward at ceiling corners where water can infiltrate walls.
What nozzle works best for cleaning shower glass?
Use a 25-degree or 40-degree nozzle held 18 inches from the glass. Start with a wider angle to prevent etching. Apply detergent first with the soap nozzle, let dwell for 3-5 minutes, then rinse with the wide fan spray for streak-free results.
