How to Use Soap With Pressure Washer?
Using soaps and detergents with a pressure washer correctly requires taking the following steps, in this specific order:
Step 1. While the pressure washer is turned off, unscrew the cap of the detergent tank.
Step 2. Pour the cleaning solution into the soap tank until the line indicates the maximum quantity allowed is reached.
Step 3. Screw the cap of the detergent tank back on.
Step 4. Connect the soap nozzle to the pressure washer wand or gun. As most nozzles are equipped with quick-connect couplers, this step will take a few seconds, while the operator needs to attach the nozzle and push it until a click is heard.
Step 5. Turn on the pressure washer.
Step 6. Using overlapping short strokes, apply the cleaning solution to the area that needs to be pressure washed. If the surface is vertical, the lower area needs to be addressed first and then move up until covering the entire surface.
Step 7. Leave in the cleaning solution for as long as the manufacturer instructs.
Step 8. If the cleaning solution dries faster than the time needed for it to do its job, apply another layer. This situation is most likely to happen while cleaning a specific surface under the sun at high temperatures. Do not allow the detergent to dry, as it could permanently damage the color of the surface.
Step 9. Rinse the soap after turning off the pressure washer and replacing the nozzle with a white one. Do not perform this procedure while the pressure washer is on, as the stream of water can cut through the skin and could cause severe injury.
Step 10. After all the detergent is out of the soap tank, fill the tank with clean water and press the trigger of the pressure washer’s gun until the stream coming out of the nozzle is detergent-free.
Do Pressure Washers Need Special Power Washer Soaps?
Pressure washers need special power washer soaps to remove gunk more efficiently. Regular soaps are not formulated to be used with pressure washers that are capable of delivering 1,500 PSI or more and can’t produce as much foam as power washer soaps. Using regular soaps with pressure washers can also damage the most sensitive parts of the machine – the pump, soap nozzle, or dispenser.
Pressure Washer Soap vs. Detergent
Pressure washer detergents and soaps are formulated differently and are suitable for different uses – washing vinyl sidings, concrete, cars, or other surfaces. Pressure washer soaps are mostly biodegradable and harmless for the environment, unlike detergents that contain harsh chemicals.
1. The ingredient list
Pressure washer soaps and detergents serve the same purpose but they are made of different ingredients. Pressure washer soaps are milder and contain animals fats, vegetable oil, and other natural ingredients. Detergents use synthetic and refined components like petroleum or coal hydrocarbons and do better than pressure washer soaps when it comes to caked-on grease.
Pressure washer soaps don’t mix well with hard or untreated water, which could leave scum or calcium residue on the surface that is being cleaned while detergents can soften hard water.
2. Ecological concerns
Detergent residue is harmful to rivers, lakes, and aquatic animals, including fish as it destroys the protective layer fishes use to protect themselves from parasites, and even kills fish eggs. Detergents can cause skin and eye irritations in humans.
Pressure washer soaps are biodegradable and mild so they don’t affect plants, pets, humans, or aquatic animals.
Pressure Washer Soap Buying Guide
When buying pressure washer soaps, factors such as purpose, concentrated or diluted formula, suds, additives, and pet and eco-friendliness should be considered, all of which are listed below.
The four main categories of pressure washer soaps by type are listed below:
- Pressure washer car soaps, which can be used on different metal surfaces
- Pressure washer soaps for plastic, such as specialized soaps for the vinyl sidings
- Pressure washer soaps formulated for concrete driveways and paths that can also be used on stone or brick masonry and work very well with surface cleaners
- Multi-purpose pressure washer soaps that are mild enough to use on almost any surface, from wood and plastic to metal
Applying pressure washer soap formulated for cleaning metal surfaces to plastic can make the plastic brittle or change its color. Using multi-purpose pressure washer soaps is the safest option, although this type of product can damage car wax or strip off a protective clear coat and cause rusting. Car wax should be applied after using a multi-purpose pressure washer soap for car washing.
2. Concentrated or Diluted Formula
Pressure washer soaps are either concentrated or diluted and packed in large bottles – half a gallon or larger. For every gallon of concentrated pressure washer soap, 3 to 10 gallons of diluted soap are obtainted. Concentrated pressure washer soaps are more economical than diluted formulas. Not owning a pressure washer detergent tank, an injector, or a cannon dispenser can make diluting concentrated pressure washer soaps challenging. Diluted pressure washer soaps are packed in small bottles that have built-in spraying mechanisms and some have a specialized adapter for the pressure washer hose.
Pressure washer soaps are formulated to produce high-quality, rich and thick suds that contribute to their cleaning effectiveness and reduce the need for scrubbing the surface. The way soap works – producing bubbles that collect dirt makes it effortless to wash the dirt off and eliminates scratching.
Some pressure washer soaps contain additives that nourish the surface being cleaned. Special purpose soaps, such as pressure washer car soaps contain wax to protect the surface and stay long on it even after the lather is rinsed.
5. Pet and Eco-Friendly
Most effective pressure washer soaps are very pet and eco-friendly. Pressure washer soaps are the nature-based alternative to the harsher detergents, except in cases when layers of dirt should be cleaned. Pet and eco-friendly pressure washer soaps are marked with “non-toxic”, “biodegradable”, or “EPA Safer Choice”.
How Do Pressure Washers Use Soap?
Pressure washers use different soap systems – built-in soap dispensers, soap injectors, and external soap dispensers to blast soap, foam it up, and create rich suds to remove dirt. The main difference between pressure washer soap systems is in soap intake.
1. Built-in Soap Dispenser
Residential pressure washers such as electric pressure washers come with built-in soap dispensers. Built-in soap dispensers are special compartments in the pressure washer where concentrated or diluted soap can be poured into and mixed with water, if needed. Once the pressure washer soap is added to the built-in soap dispenser, the pressure washer starts blasting it with water. Using a black foaming nozzle on the tip of the pressure washer wand can maximize the amount of lather the pressure washer produces.
2. Soap Injector
Pressure washers with soap injectors typical for gas pressure washers require inserting the injector tube into an external bucket filled with soap. A soap injector is a siphoning tube that can be installed near the pressure washer’s pump and supplies it with the pressure washer soap diluted in a bottle. Pressure washer soap flows through the pressure washer pump and wand, mixes with water, while the black foam nozzle tip gets it foamed up.
3. External Pressure Washer Soap Dispenser – Cannon
Pressure washers that aren’t designed to have chemicals pass through their pump use external soap dispensers or cannons. External soap dispensers – small bottles filled with pressure washer soap and water are mounted on the top of the pressure washer wand. As the water is sprayed through the pressure washer, the soap is siphoned by the high pressure and the lather is blasted in a similar way as with a regular dispenser. More information about pressure washers and pressure washer accessories can be found on this page.
Pressure Washer Soap Usage Tips and Tricks
1. Know Your Equipment
When choosing between pressure washer soaps, attention should be paid to the type of pressure washer soap dispenser. Soap injectors or cannons that are attached to the end of the pressure washer wand should be used with pressure washers that don’t have built-in soap dispensers. Pressure washers that have exposed pressure washer pumps come with valves that can be used as pressure washer soap injectors. Pressure washer pump oils should be used to keep the pump working properly.
2. Personal Safety
2.1. Wear appropriate clothes
Protective clothing, water-resistant boots, ear muffs of earplugs, breathing masks, and eye goggles should be worn when applying pressure washer soap to prevent skin or eye irritation or inhaling harsh chemicals.
2.2. Don’t use ladders
Standing on ladders is not recommended when pressure washing and applying pressure washer soap. The high pressure the pressure washer delivers can make the user lose balance, which is why pressure washer extension wands should be used when washing less accessible areas.
2.3. Protect your plants and pets
Covering plants around the surface that is being cleaned using pressure washer soaps and detergents with a waterproof material or tarp will protect them from chemicals.
3. Applying Soap
3.1. Don’t let soap dry
When applied, the pressure washer soap shouldn’t sit for too long on the surface, otherwise, it will dry and become harder to rinse off. When cleaning larger surfaces, the pressure washer soap should be applied to smaller areas, rinsed, and then another area should be soaped.
3.2. Bottom-up VS from top-down
When washing cars, the pressure washer soap should be sprayed on the roof so that it flows down the car’s body, although this should be done swiftly so that the soap doesn’t dry. When washing vinyl sidings, the pressure washer soap should be applied in segments, from the bottom to the top.
FAQ About Pressure Washing Chemicals
1. Can I use dishwasher soap with a pressure washer?
Dishwasher soap shouldn’t be used with a pressure washer because it can cause damage to the pressure washer pump. Using dishwasher soap with pressure washers that use cold water only won’t produce as much lather as pressure washer soaps produce. Applying regular soap instead of pressure washer soap to the car surface might eat through the paint’s protective clear coat and cause rust and corrosion in case there is no sufficient amount of wax or sealant.
2. Are pressure washing chemicals safe for the environment?
Some pressure washer chemicals such as pressure washer soaps are safe for the environment while pressure washer detergents aren’t as safe because they contain strong, non-biodegradable chemicals.
3. Can I use household bleach in a pressure washer?
No, household bleach shouldn’t be used in a pressure washer because it can damage the seals on the pressure washer pump. Household bleach should only be sprayed using a spray bottle or applied using a cloth when removing mold or discoloration.
4. How to make a homemade pressure washer soap?
To make a homemade pressure washer soap, ⅓ cup of laundry detergent, 1 gallon of water, 1 cup of vinegar, and ⅔ cup of household cleaner should be used. However, making homemade pressure washer soaps may not be cost-efficient because concentrated pressure washer soaps can produce up to 30 gallons of the product when it is diluted with water.
5. Can you power wash without pressure washer soap?
It is possible to power wash without pressure washer soap, however, pressure washing using the soap is more efficient so grease and oil stains are easily removed.
