Cleaning — FAQ
Will a pressure washer damage my tile grout?
When used correctly, no. Stay under 2500 PSI and use 25-degree or wider nozzles. Test on a hidden spot first. Our tests showed 2100-2300 PSI with proper technique cleans grout without erosion.
What's better for tile: electric or gas pressure washers?
Electric models offer precise pressure control and lower noise for indoor/outdoor tile work. Gas units provide more power for large patios but risk excessive pressure. For most homeowners, electric is safer and more convenient.
Can I use bleach or harsh chemicals in the soap tank?
Avoid bleach—it degrades seals and can discolor tile. Use manufacturer-approved detergents or mild alkaline cleaners designed for pressure washers. The Giraffe Tools and Westinghouse soap tanks handle pH-neutral cleaners safely.
Which nozzle is safest for ceramic tile surfaces?
Always start with a 40-degree white tip for surface cleaning. It distributes pressure over a wide area, preventing cracks. For grout lines, step to 25-degree green tip. Never use 0-degree or 15-degree tips on tile faces.
How long of a hose do I need for patio cleaning?
Minimum 50 feet for average patios. The Giraffe Tools' 100ft hose lets you clean 2000 sq ft without moving the unit. Shorter hoses require frequent repositioning and increase tip-over risk on wet surfaces.
Do I need a foam cannon for tile cleaning?
For deep grout stains, yes. Foam cannons apply thicker detergent that clings vertically to shower walls and penetrates pores. Standard soap tanks work for light maintenance, but the ePX3100v's detachable cannon cuts scrubbing time by 60%.
