FAQs
1. What can a gas pressure washer clean?
Everything from cars and trucks to driveways, decks, some kinds of outdoor furniture, vinyl siding, as well as brickwork, can be cleaned. Most potent gas-pressure washer choices can handle a wide range of surfaces as long as the pressure is adjusted to the task.
2. Do gas pressure washers need to be oiled?
