One of the biggest decisions a professional cleaner or contractor faces is whether to use hot water or cold water pressure washing for a job. Both approaches are effective, but each has specific advantages depending on the surface, the type of grime you’re tackling, and the efficiency you need on the job site.
At Veloci Performance Products, we equip cleaning professionals with the tools to get the most out of either method. Whether you’re breaking down grease with hot water or blasting away dirt with cold water, understanding the difference can save you time, extend the life of your equipment, and deliver better results for your clients.
Hot Water Pressure Washing: Power for Tough Jobs
Hot water pressure washing combines high pressure with elevated water temperatures (up to 200°F or more) to deliver an unmatched cleaning punch. Heat helps to break down oils, grease, and sticky residues in a way cold water simply can’t.
Best Uses for Hot Water
- Cleaning heavy equipment and machinery
- Degreasing restaurant floors, dumpsters, and commercial kitchens
- Oil-stained driveways or garages
- Industrial settings with chemical or petroleum buildup
Benefits of Hot Water
- Cuts through grease and oil without needing excessive chemicals
- Sanitizes surfaces by killing bacteria and mold more effectively
- Saves time since grime loosens faster under heat
Veloci Products for Hot Water Applications
Durability is key when using hot water equipment. Veloci products are designed to withstand higher temps without premature wear:
- Acqualine SGS35 Spray Gun – Ergonomic and built to handle hot water applications while reducing fatigue.
- KobraJet Black Hose – Engineered for heat resistance, ensuring long service life under hot water conditions.
- Turbo Nozzle (RotoJet) – A rotating blast of power that pairs perfectly with hot water to cut through stubborn grime.
Cold Water Pressure Washing: Versatility and Efficiency
Cold water pressure washing is the go-to method for general cleaning tasks. While it doesn’t have the grease-cutting advantage of hot water, it’s incredibly versatile, cost-effective, and perfect for surfaces that don’t require heat.
Best Uses for Cold Water
- General exterior cleaning (siding, decks, patios)
- Vehicle detailing and fleet washing
- Concrete, brick, and stone surfaces
- Routine residential and commercial maintenance
Benefits of Cold Water
- Affordable to operate since no heating unit is required
- Safe for most surfaces, especially when combined with foam detergents
- Lighter equipment makes it more portable for mobile cleaning setups
Veloci Products for Cold Water Applications
Cold water systems benefit most from efficiency tools that speed up cleaning while protecting surfaces:
- PF22 Foam Cannon – Italian-made, patented design that produces thick, clinging foam for pre-soak and chemical application.
- Mezzo Valve – Quickly switch between high-pressure rinsing and downstream chemical injection for soft washing setups.
- Acqualine Nozzle Guards – Protect painted and delicate surfaces from accidental scratches while detailing.

Which Method Should You Choose?
The right choice depends on the type of work you do:
- If you’re working in automotive shops, industrial facilities, or food service environments, hot water pressure washing will give you the edge in degreasing and sanitizing.
- If you’re focused on residential work, vehicle detailing, or general exterior cleaning, cold water systems combined with the right foam cannons and nozzles will provide all the cleaning power you need.
Many professionals invest in both types of setups, allowing them to switch between hot and cold water systems depending on the job. With Veloci’s selection of high quality pressure washing guns, hoses, nozzles, and foam cannons, you can adapt your rig to any application.
Hot Water vs. Cold Water: Both Have Advantages
Both hot water and cold water pressure washing have unique advantages. Hot water delivers unbeatable results for grease and heavy industrial grime, while cold water offers versatility, portability, and affordability for everyday cleaning.
The key is equipping yourself with the right tools. From the PF22 Foam Cannon and Mezzo Valve for cold water applications to the KobraJet Hose and Turbo Nozzle for heated systems, Veloci Performance Products has the gear professionals trust.
