Rent the Machine, Grab the Chemicals: Job Kits
A pressure washer alone moves dirt around. The right chemical does the actual cleaning. Pair your rental with the pro mix for the job and you finish in half the time.
House Wash Kit
Cold water machine + downstream injector (included) + house wash chemicals and sodium hypochlorite. Vinyl, brick, stucco, gutters.
Driveway and Concrete Kit
Cold water machine + 20" or 24" surface cleaner + concrete cleaners. Add a degreaser for oil spots.
Deck and Fence Kit
Cold water machine (run the 40 degree tip) + deck and wood cleaners, then finish with deck stain and sealer.
Fleet, Restaurant and Grease Kit
Hot water skid + degreasers or kitchen exhaust cleaners. Hot water cuts grease on contact.
Roof Cleaning Kit
Soft wash approach: cold water machine on low pressure + roof cleaning chemicals. Ask us about mix ratios at pickup.
Own Your Gear Instead?
We stock pressure washers for sale, surface cleaners and quick connect tips. Rent first, then buy the same class of machine once you know what the job needs.
Why Rent From a Pressure Washing Supply Store
These are the same commercial machines the pros run, serviced in our own repair shop between every rental. You also get real advice with the keys: which tip for which surface, how to downstream chemicals, what mix to use. Try doing that at a big box rental counter. And if you're mid-job and something comes up, you're renting from people who answer the phone and know the machine.

Common Questions
What do I need to rent?
A driver's license and a card on file. Reserve online at our rental site or call (301) 519-9274 and we'll have it ready at the dock.
Do rentals come with tips and an injector?
Yes. Every machine goes out with 5 quick connect tips and a downstream injector included in the price.
Cold water or hot water?
Cold water handles most house, deck and concrete work. Hot water cuts grease and oil on contact, which is why restaurants, fleets and heavy equipment jobs rent the Hydrotek. Not sure? Tell us the job and we'll tell you the machine.
Can I rent a surface cleaner for my own machine?
Yes, as long as your machine has the flow for it. The 20 inch runs on most 4 GPM machines, the 24 inch needs 5+ GPM, and the 36 inch needs 8+ GPM.
Do you deliver?
Rentals are pickup at our Gaithersburg dock. Emergency delivery inside Montgomery County is available for a fee when a truck is free; call to check.
Can I get a discount on a repeat rental?
Yes. Leave us a Google or Facebook review after your rental, show it at the counter, and take 10% off your next rental.
