The IK Multi Pro 2 360 Upside Down Sprayer (#81675) is a professional-grade compression sprayer designed for demanding automotive detailing, cleaning, maintenance, and industrial applications. Its standout feature is a specialized 360° spraying system that lets it operate in virtually any position, including completely upside down, making it ideal for reaching wheel wells, undercarriages, engine bays, and other awkward, hard-to-reach areas that leave a standard sprayer sputtering. Built for durability and chemical resistance, it handles a range of compatible cleaning chemicals, so it's ready for the products you actually use on the job.

It's built with professional users in mind detailers, cleaning pros, and anyone doing serious maintenance work but it's just as at home for the dedicated enthusiast who wants pro-level tools. With a 1.5-liter (50 oz) usable capacity, an ergonomic pump and handle, a wide stable base, and tool-free disassembly, it delivers plenty of working volume while staying compact and easy to handle. The payoff is a sprayer that combines professional chemical resistance with genuinely convenient 360° spraying to make difficult applications faster and easier, whether you're laying down wheel cleaner, detailing chemicals, disinfectants, or other compatible solutions.

Key Features

• 360° spraying system works upside down – Sprays continuously at any angle, even inverted, so you can reach wheel wells, undercarriages, engine bays, and other difficult spots without losing pressure or flow.
• Chemical-resistant construction – Built to handle acids, disinfectants, neutral cleaners, and professional cleaning chemicals (per IK's chemical compatibility chart), so it stands up to aggressive detailing and cleaning products.
• Dual included nozzles – Ships with both an adjustable conical nozzle and a fan nozzle, letting you match the spray pattern precisely to the task at hand.
• 36 PSI safety valve with manual depressurization – An integrated safety valve set to 2.5 bar (36 PSI) with a manual pressure-release option gives you controlled, safe operation and easy depressurizing before you open the tank.

Features & Benefits

The heart of the Multi Pro 2 360 is its 360° spraying system, which draws solution and maintains spray in virtually any orientation, the reason it can spray upside down. For automotive work, that's a genuine advantage: you can get up into wheel arches, along the undercarriage, and into the engine bay without contorting the sprayer or the chemical running dry. It's paired with a durable translucent tank featuring clear level markings, so you can monitor how much solution is left and accurately prepare diluted products by the numbers, and a wide filling opening that makes adding, mixing, and emptying chemicals easier while helping reduce spills.

Chemical resistance is where this sprayer earns its professional stripes. It's built to work with a variety of compatible cleaning chemicals — it's particularly resistant to acids and well suited to all-purpose cleaners, disinfectants, and neutral products, thanks to quality chemical-resistant seals. Because chemical compatibility is a safety matter, IK provides a Chemical Product Table, and it's important to confirm your specific product against it before filling (compatibility is more limited with solvent-based products, oils, and petroleum by-products). A protective sleeve for the valve chamber adds another layer of durability where the sprayer takes the most stress.

The design details are dialed in for real-world professional use. It has an ergonomic pump and handle for comfortable pressurizing, a wide, stable base so it won't tip while you work, and a safety lock to prevent accidental discharge. Tool-free disassembly makes cleaning and maintenance quick, no tools to hunt down between jobs, and interchangeable colored caps let you identify which chemical is in which sprayer at a glance while providing handy storage for extra nozzles. It's also designed to accept other types of nozzles and accessories for added versatility. With a 1.5-liter (50 oz) usable / 1.9-liter (64 oz) total capacity and a light net weight of just 0.56 kg (1.23 lbs), it balances working volume with easy handling.

Installation & Setup
This is a ready-to-use handheld sprayer, no installation required, just simple preparation before each use.

• Filling: Unscrew the cap and add your solution through the wide filling opening, using the translucent tank's level markings to measure and dilute accurately.
• Chemical check: Confirm your product against IK's Chemical Product Table before filling to ensure compatibility.
• Nozzle selection: Fit either the adjustable conical nozzle (for an adjustable stream-to-cone pattern) or the fan nozzle (for a wider spray), depending on the application. Additional nozzles and accessories can be fitted for other tasks.
• Pressurize: Pump to build pressure; the safety valve caps pressure at 2.5 bar (36 PSI). Engage the safety lock when not spraying.
• Depressurize: Use the manual depressurization option to safely release pressure before opening the tank.

Care & Maintenance
Following IK's care guidance keeps the sprayer safe, reliable, and long-lasting:

• After every use: Depressurize the sprayer and clean it with water.
• Test the safety valve: Periodically trigger the mechanism to confirm it releases pressure smoothly.
• Dispose of residue properly: Collect and dispose of leftover solution according to applicable legislation and regulations.
• Clear a clogged nozzle: Clean it with water only — never use metallic objects, which can damage the nozzle.
• Clean the tank regularly: Rinse with clean water after each use and use a specific detergent if needed to remove stubborn residue. Removing chemical residue prevents unwanted reactions and protects operator health.
• Clean the handle filter: If the filter in the handle clogs, remove it and clean it with water.
• Storage: Store the sprayer under cover, away from freezing temperatures and extreme heat (between 5°C and 30°C / 41°F and 86°F).
• Lubricate the seals: To prolong seal life, regularly apply grease to the sprayer's moving parts.
• Inspect and replace components: Check nozzles, filters, and hoses; replace any worn or damaged parts with original IK spare parts to ensure safe, reliable service.

Warranty
IK sprayers are backed by a manufacturer's warranty against defects in materials and workmanship under normal use.

• Typically covered: Manufacturing defects in materials and workmanship under normal, intended use.

Terms to Know

• Compression sprayer: A handheld sprayer you manually pump to build air pressure in the tank, which then propels the liquid out through the nozzle.
• 360° spraying system: An internal pickup design that keeps drawing solution and spraying no matter how the sprayer is oriented — including upside down.
• Usable vs. total capacity: Usable (1.5 L / 50 oz) is how much solution you can actually spray; total (1.9 L / 64 oz) is the full tank volume, with the extra space left for air/pressure.
• Safety valve/depressurization: A valve that limits tank pressure to a safe maximum (36 PSI here) and lets you manually release pressure before opening the tank.
• Adjustable conical nozzle: A nozzle you can twist to vary the spray from a focused stream to a cone mist.
• Fan nozzle: A nozzle that produces a flat, wide fan-shaped spray pattern for covering broad areas.
• Chemical compatibility chart: IK's reference table showing which chemical types the sprayer's materials safely handle — check your product against it before filling.
• FPM/Viton-type seals: Chemical-resistant seal material used in professional sprayers to withstand aggressive cleaning chemicals (confirm seal type for your unit if chemical resistance is critical).
• Safety lock: A lock that prevents the trigger from discharging accidentally.
