Yes, laundry detergent can both stain and potentially damage a carpet. If spilled, especially if it's a brightly colored liquid, it can leave a vibrant stain. While a single small spill is unlikely to ruin the carpet, regular exposure is not recommended. Over time, laundry detergent can leave a residue, negatively affect the carpet's appearance, and even break down its fibers.

Our guide can also work for old tomato stains. If you’re trying to get rid of a lingering spot from spaghetti dinners past, you can skip step one and jump directly to step two. 

Pro tip: Allow soaking time for older stains. We recommend waiting at least 10 minutes between applying your cleaning solution and blotting it up.

Yes, if you want to use a carpet cleaner to its full potential, complete multiple passes and water changes until the water comes out clear. If it’s been a while since you last cleaned, it’s common for this to take up to 10 passes or possibly more. Once the water runs clear, you’ll know all the dirt and grime are gone.

You should avoid using a pressure washer on any surface or item that could be damaged by the high-pressure spray, as some materials are too delicate to withstand the force.

Key items and surfaces to avoid include:

• Electrical Components: Never pressure wash electrical systems, as water can cause short-circuits and create a safety hazard. This includes utility meters, breaker boxes, electrical outlets, generators, and HVAC or air conditioner units.

• Delicate and Fragile Materials: Fragile items can crack, shatter, or be stripped by the pressure. Avoid pressure washing windows, glass, light fixtures, shingled roofs (especially asphalt), and stucco.

• Painted, Stained, or Sealed Surfaces: Unless your goal is to strip the finish, do not pressure wash painted surfaces, stained wood (like decks), or anything with a protective seal that could be stripped away. Be especially cautious with older surfaces that may contain lead paint.

• Soft Woods and Certain Decking: Delicate surfaces like softwood, composite decking, and antique or wooden patio furniture can be etched or damaged. If you must wash wood, use a lower-powered pressure washer with a wide-angle nozzle to prevent damage.

• Living Things: Never use a pressure washer on people, pets, or plants. The force can cause serious injury and will destroy landscaping.
