Solution All-Purpose Cleaner RTU - 32oz

NO MIXING. JUST CLEAN.

Solution RTU is Solution All-Purpose Cleaner pre-diluted at 4:1. The same emulsification-based formula, ready to spray straight from the bottle. Built for the jobs that hit the 4:1 sweet spot: wheels, tires, fender wells, engine bays, undercarriage, and light interior cleaning. When you don't want to mix, this is the bottle to grab.

• Pre-Diluted at 4:1: Same Solution formula, mixed and ready. Skip the math, grab and spray.
• Emulsifying Action: Surfactants and chelating agents loosen grime. Works across coated and uncoated surfaces.
• Need The Concentrate? If you want to dilute Solution at 10:1 for interior cleaning and paint prep, or run it 1:1 for heavy degreasing on caked grease and dried mud, grab the Solution Gallon.
• Not For: Sensitive interior surfaces or high-end interior work. For those, we recommend our Leather & Interior Cleaner to be safe.

How to Use

Method 1: Wheels & Tires

1. Spray Solution RTU directly onto wheel face, barrel, and tire sidewall.
2. Agitate with The Palm Pro for the wheel and The Tire Tamer for the tire.
3. Rinse thoroughly with water. Don't let it dry.

Method 2: Engine Bays, Fender Wells & Undercarriage

1. Spray Solution RTU directly onto the engine bay, fender wells, plastic liners, or accessible undercarriage surfaces. 4:1 is the standard strength for these jobs when surfaces aren't caked with grease or mud.
2. Agitate with The Bristle Boss for engine bays or The Reacher for fender wells and undercarriage.
3. Rinse off completely. Don't let it dry.

Method 3: Light Interior Cleaning

1. Spray Solution RTU directly onto a microfiber towel. Never spray directly onto an interior surface.
2. Wipe down the surface.
3. Buff dry with a second clean microfiber towel.

Detailer Tips

• Don't ever let it dry.
• Always test on fragile or high-end interior surfaces first.
• For heavy degreasing on caked grease, dried mud, or neglected undercarriages, step up to the Solution Gallon at 1:1.
