Description
The Detail King Stainless Steel Tank Sprayer (3 Gallon) uses pressurized air to quickly and efficiently dispense interior cleaners, degreasers, shampoos, wheel cleaners, and other heavily used detailing chemicals. The stainless steel body holds up to 2.5 gallons of product (the rest of the 3-gallon tank is air headspace for pressurization), replacing cheap plastic bottle sprayers and pump-style jugs that crack, leak, and dissolve under solvent loads in a busy shop.

Highlight specs:
- 2.5 gallons max solution input (3-gallon tank with air headspace)
- 125 PSI max pressure with built-in safety relief valve
- One 100 PSI charge typically lasts an entire tank of product
- 15-foot coiled hose for reaching engine bays, wheel wells, and overhead panels
- Adjustable nozzle: stream to mist pattern
- Viton-sealed trigger rated for aggressive chemicals
The stainless body resists acids and alkalines, the Viton-sealed trigger holds against aromatic solvents, and a one-shot 100 PSI charge from an air compressor (or a 12-volt portable tire inflator from the truck) gives you a full tank of consistent spray pressure with no mid-job pumping.

Who this is for:
- Mobile detailers who need one durable sprayer they can charge from a 12V inflator on the truck and carry to every wheel, engine bay, and door jamb on the route
- Shop owners and body shop techs running degreasers, wheel cleaners, or panel-prep solvents that destroy plastic pump sprayers
- Engine bay and wheel specialists who apply caustic or acidic chemistry on every vehicle and need a solvent-resistant body
- Detailers upgrading from leaky plastic pump-style sprayers that need re-pumping every 30 seconds
- High Volume Shops that don’t want to spend time filling bottles daily and squeezing triggers constantly on their most heavily used products
Stainless vs plastic pump sprayer

Plastic pump sprayers (the $10-15 garden-style bottles) are fine for water, glass cleaner, and weak APC dilutions. They fail fast on:
- Strong degreasers (citrus, butyl, or solvent-based): plastic gaskets swell, the trigger sticks open
- Acidic wheel cleaners: the bottle clouds, the pump shaft corrodes
- Tar removers and bug removers: aromatic solvents craze the polyethylene
- Hot environments (truck bed in summer): plastic warps, seals deform
Our pressurized stainless tank handles all of the above without rebuilding the sprayer every few weeks, will save you time daily on refilling along with time savings on spraying, and will reduce finger fatigue for high volume detailers. The trade-off is the upfront price and the need for an air source to pressurize, which is solved by any shop compressor or a $30 portable 12V tire inflator.

Chemistry compatibility

This sprayer is designed for the full range of detailing chemistry, including:
- Car wash soaps and shampoos (concentrated or pre-diluted)
- Degreasers including Citrus Degreaser and butyl-based engine cleaners
- Bug removers including DK Bug Remover
- Glass cleaners including Crisp RTU
- Tar removers and adhesive removers
- Non-acid wheel cleaners and iron removers
- Tire dressings (water-based; for solvent-based dressings, dedicate one tank)
- Interior Cleaners including Extractor Soap, Pink Power, & Magic Cleaner
For interior surface cleaners like Koch-Chemie Pol Star, this sprayer works at the recommended 1:5 dilution for fast coverage on door panels and headliners. For high-foam applications (snow foam, pre-wash foam blankets), the IK e-Foam Pro 2 battery-powered foam cannon is the better tool because it generates dense foam without an external compressor.
Features & Details
- Stainless steel that outlives plastic. The bottle will not rust or crack the way cheap plastic pump sprayers do in body-shop use.
- Adjustable spray pattern. Turn the nozzle from a tight stream to a wide mist and pick the release point that fits the job.
- Truly portable. Once pressurized it goes anywhere, with a 15-foot hose for tight spots; you can even charge it from a 12-volt tire inflator plugged into your vehicle.
- Handles a full range of detailing liquids. Soaps, dressings, citrus degreaser, bug removers, glass cleaners, tar removers, and non-acid wheel cleaners, for engines, wheels, wheel wells, and door jambs.
For Best Results
1. Fill the tank about three-fourths full of product (roughly 2 to 2.5 gallons), leaving the remaining space for air
2. Connect a standard air chuck (same one you use for tire valves) to the inlet and pressurize to a maximum of 125 PSI
3. Pull the trigger to dispense; adjust the nozzle from stream to mist for the application
4. Refresh pressure if needed; one 100 PSI charge typically lasts a full tank of product

Frequently Asked Questions

How do you pressurize this tool?

From an air compressor. The tank charges through a standard tire valve stem, so the same chuck you use to air up your car's tires is what fills this sprayer.
What chemicals can I use in this sprayer?

Any liquid that can be sprayed will work. In practice, most detailers load it with the chemicals they reach for all day: degreasers, bug removers, and all-purpose cleaners.
How much product and air should I put in the container?

Fill the tank 2/3 to 3/4 of the way with your chemical, then charge the remaining space with air. A built-in relief valve opens automatically once the container is full, so the canister can never burst from too much pressure.
Can you put acid or degreaser in this sprayer?

Yes. The stainless steel body and Viton-sealed trigger handle alkaline degreasers and most acidic wheel cleaners (iron removers and mild acidic blends) that crack plastic pump sprayers. For aggressive acids like hydrofluoric or concentrated phosphoric, rinse the tank, hose and sprayer immediately after use for best results - these chemicals will eat away at multiple components so immediate rinsing will help to extend their life. Most detail-grade vehicle chemistry is safe.
What if I don't have a shop air compressor?

A portable 12-volt tire inflator that plugs into your vehicle's accessory socket pressurizes the tank to working pressure. This is how most mobile detailers run it on a route without hauling a full compressor. Small pancake compressors work fine too. One 100 PSI charge lasts a full tank. Some gas stations also have free air for filling tires which can be used for pressurizing your tank sprayer when you stop for gas!
