Cleaning — FAQ
Can carpet steam cleaners actually work on concrete driveways?
True steam cleaners like the McCulloch MC1385 work excellently on concrete, using high-pressure steam to dissolve oil and grease. Carpet shampooers are designed for fibers and won't effectively clean bare concrete surfaces.
What's the difference between steam cleaning and hot water extraction?
Steam cleaners heat water to 200°F+ vapor that sanitizes and dissolves stains without chemicals. Hot water extraction uses 140-180°F water with detergent, then vacuums it up—better for deep carpet fibers but requires chemical solutions.
How much pressure do I need for driveway oil stains?
For driveway oil stains, you need at least 50 PSI steam pressure or 15Kpa water extraction suction. The McCulloch's 58 PSI steam cuts through motor oil, while the uwant's 18Kpa suction pulls it from concrete pores.
Are these steam cleaners safe for car interiors?
Yes, when used properly. Keep steam wands moving to avoid overheating leather or vinyl. Test water extraction machines on hidden areas first. The McCulloch's variable steam control and uwant's temperature settings prevent damage to sensitive materials.
Do I need chemicals to clean my driveway?
Not with true steam cleaners—they use only water. For heavy grease, you may need degreasers with water extraction machines. The McCulloch's chemical-free operation is ideal for environmental concerns and areas with runoff restrictions.
Can I use carpet cleaners on outdoor rugs in my driveway?
Absolutely. All tested models work on outdoor rugs and automotive carpets placed on driveways. Upright models like the BISSELL HydroSteam series excel at large area rugs, while canister units offer more precision for edges and corners.
