SOLUTION ALL-PURPOSE CLEANER

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.

1 Gallon

ONE CLEANER. EVERY SURFACE.

Solution is a heavy-duty all-purpose cleaner that lifts road film, tire residue, and interior grime through emulsification. It loosens dirt rather than burning it like your standard degreaser. Dilute it down for interior work, run it mid-strength for wheels and engine bays, or full strength for heavy degreasing. One bottle, every job.

• Emulsifying Formula: Surfactants and chelating agents loosen dirt at the molecular level.

• Fully Dilutable: Mix to match the job. 10:1 for light interior cleaning and paint prep. 4:1 for wheels, tires, rubber, fender wells, and most engine bay or undercarriage work. 1:1 only when 4:1 isn’t enough. Heavy degreasing on caked grease, dried mud, or undercarriages that haven’t seen soap in years.

• Multi-Surface Coverage: Cleans leather, vinyl, plastics, tires, wheels, undercarriage, engines, and paint.

• Concentrate Format: One gallon mixes down into a lot of bottles. Built for shop use and serious DIY.

• 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: INTERIOR CLEANING (10:1)

1. Dilute 1 part Solution with 10 parts water in a Shine Supply 32oz spray bottle.

2. Spray Solution directly onto a microfiber towel or The Bristle Boss. Never spray directly onto an interior surface.

3. Wipe or agitate the surface.

4. Wipe clean with a fresh microfiber towel. Don’t let it dry.

METHOD 2: PAINT PREP (10:1)

1. Dilute 1 part Solution with 10 parts water in a Shine Supply 32oz spray bottle.

2. Pre-rinse the panel with water.

3. Spray Solution directly onto the panel.

4. Agitate if needed, then rinse off completely. Don’t let it dry.

METHOD 3: WHEELS, TIRES & RUBBER (4:1)

1. Dilute 1 part Solution with 4 parts water.

2. Spray directly onto wheels, tires, rubber floor mats, or fender wells.

3. Agitate with The Palm Pro for the wheel and The Tire Tamer for the tire.

4. Rinse thoroughly with water. Don’t let it dry.

METHOD 4: ENGINE BAYS & UNDERCARRIAGE (4:1)

1. Dilute 1 part Solution with 4 parts water. This is the standard strength for most engine bay and undercarriage cleaning when surfaces aren’t caked with grease or mud.

2. Spray directly onto the engine bay or undercarriage.

3. Agitate with The Bristle Boss for engine bay work or The Reacher for undercarriage.

4. Rinse thoroughly with water. Don’t let it dry.

METHOD 5: HEAVY DEGREASING (1:1)

1. Dilute 1 part Solution with 1 part water. Reserve this strength for the heaviest jobs. Caked engine grease, dried mud knockdown, neglected undercarriages, or anything 4:1 won’t touch.

2. Spray onto the affected area.

3. Agitate with The Bristle Boss or The Reacher.

4. Rinse thoroughly. Don’t let it dry. It’s critical at this strength.

DETAILER TIPS

• Start at the weakest dilution that gets the job done. Most engine and undercarriage work is a 4:1 job, not a 1:1 job.

• Don’t ever let it dry.

• Always test on fragile or high-end interior surfaces first.

• Grab three Shine Supply 32oz bottles and pre-dilute one at 10:1, one at 4:1, and one at 1:1. Use colored tape to label and differentiate them.
