Which Nozzle Should I Use For Deck Cleaning
Choosing the right pressure washer nozzle is actually more important than the PSI or GPM of your pressure washing unit of measurement. It'due south the nozzle that creates the pressure in the h2o stream that hits your cleaning surface. Nozzles work because of physics. Restricting the water flow from a continuous pressure source creates more velocity (speed), which creates more force (pressure) in the spray.
If y'all cull a nozzle that creates too much pressure for the surface, you take a chance property damage, such as peeling pigment from your machine, gouging chunks out of your wood deck, and even punching through mortar in your brick walls or driveway.
Sometimes y'all have to experiment to see what nozzle will work best. However, information technology's better to have a firm thought of what yous demand before y'all become started.
Types of nozzles
Most force per unit area washers come with iv – 5 colour-coded nozzles in the box:
- 0-caste (red)
- 15-caste (yellow)
- 25-degree (green)
- xl-degree (white)
- Soap (black)
The blood-red 0-degree nozzle makes a small, concentrated, yet very powerful water jet. It'due south best for removing tough stains such equally mildew, tar, glue, oil, tree sap, dried gum, etc. from very difficult surfaces such equally concrete and hard metal. Practise NOT use this nozzle on wood, siding, or any other soft surfaces. Information technology tin cause serious lacerations every bit well, and so just use this nozzle if you absolutely need it.
We recommend throwing out the 0-degree nozzle to prevent injuries, since homeowners rarely need to use it.
The yellow fifteen-degree nozzle has a narrow, nevertheless powerful fan that is nifty for removing dirt, rust, paint, or mildew for surface prep on near surfaces earlier painting, staining, or re-sealing. If used with caution from a distance, it can be good at removing caked mud from iv×iv vehicles and subcontract equipment.
The green 25-caste nozzle is for full general cleaning of well-nigh surfaces. It's the almost common all-purpose nozzle around the habitation. The wider spray is great for sweeping away droppings, mud, leaves, and other grime that isn't deeply embedded in a surface. Information technology can be used on decks, driveways, vinyl siding, cars, boats, patio furniture, and lots more.
The white 40-degree nozzle produces a wide, gentle pressure spray for light cleaning of more fragile surfaces such as windows, blinds, flower pots, cars, etc. It's too great for rinsing off detergents.
The black soap nozzle is the lowest pressure nozzle with the largest orifice. It decreases the h2o velocity, which increases pressure in the hose. This pulls detergent from the detergent tank so y'all tin can apply lather apace and easily.
These nozzles are unremarkably sold separately, simply sometimes come with the force per unit area washer:
Turbo or rotary nozzles sometimes come up with the pressure level washer, but are normally sold as an accompaniment. They combine the pressure of a 0-degree nozzle, spinning at 5,000 – 9,000 RPM, and expanded to a fifteen-degree circular spray design. This can cut your cleaning time in one-half. But they nonetheless produce a powerful spray, capable of removing stuck-on grime, stripping paint, etc.
For a gentler option, the rotary deck cleaning nozzle makes a wider jet to deep clean more delicate, porous surfaces such every bit wooden decks and fences.
Adjustable/variable nozzles sometimes come up with pressure washers. This is a unmarried piece at the end of the cleaning wand. It's like 6 nozzles in i that you simply turn to adjust to the degree that you need.
Accessory/specialized nozzles come in many types for many different uses. They are ever sold separately and include second-story extension wands, scrub brush attachments, rotating brushes, gutter cleaners, flat surface cleaners, scrubbing brooms, cream blasters, and many more than.
How to choose the right nozzle when you lot're not sure
If y'all're non sure which nozzle you lot need, or if you're new to pressure level washing or trying a new machine for the first time, follow these general rules.
- Let common sense guide you – For case, if you need to clean a wooden deck or vinyl siding, yous know you won't demand a 0-degree nozzle, and you probably won't need a 15-degree nozzle unless you lot have an absolutely filthy surface that you're prepping for paint or stain.
- First broad, then work your way in – Showtime with the widest bending, such every bit a 40-caste nozzle to begin with.
- Keep your distance at first – Get-go about 24 inches away from the surface. Gradually move closer until you see the desired results. Don't get closer than 6 inches from the surface. If it's not removing dirt from that close, then endeavor a narrower angled nozzle.
- Examination on a small, inconspicuous area – Experiment on a corner of the deck where the grill normally sits, for case. If it happens to get damaged, at least you lot can hibernate information technology.
