In the world of cellar management, there are two types of landlords: those who hope their lines are clean, and those who know their lines are clean.
The difference isn’t in the effort they put in. It’s in the colour of the fluid they use.
If you are still using cheap, clear line cleaner (often sold as “Economy” or “Maintainer”), you are flying blind. You are soaking your lines for 20 minutes and assuming the bacteria is dead.
To be an “Expert Operator,” you need feedback. You need a chemical that talks to you. You need Purple Line Cleaner.
The “Feedback Loop” Simulator
See the difference between hoping your lines are clean and knowing they are clean.
Purple (pH 12+)
Fresh, caustic, strong. The line is sterile. This is your goal.
Green (pH 9-11)
Eating dirt. Encountered yeast/sugar. Reaction is active. Keep soaking.
Clear/Yellow (pH <9)
Exhausted. Neutralized by filth. The fluid has stopped working.
The Behavioral Economics of Clean
Rory Sutherland teaches us that “Signalling” is crucial. Line cleaning is usually invisible. By using Purple Cleaner, you make hygiene visible. If a regular sees purple fluid in the tap, it signals competence and care. Use the fluid as a marketing tool.
Data is Power.
You rely on visual data (Purple vs Green) to manage your cellar hygiene. Why aren’t you using data to manage your kitchen profitability?
The Science: The "Traffic Light" System
Pipeline Professional (and its top-tier rivals like Proton) uses a specific alkaline indicator dye. This isn't just to make it look pretty; it is a chemical sensor.
Here is how the "Conversation with Chemistry" works:
- Purple (pH 12+): The fluid is fresh, caustic, and strong. The line is clean.
- Green (pH 9-11): The fluid has encountered organic matter (yeast/sugar). The chemical reaction is happening. It is "eating" the dirt.
- Clear/Yellow (pH <9): The fluid is exhausted. It has been neutralized by the amount of filth in your lines.
The "Clear Fluid" Trap: If you use clear cleaner, you pump it in, wait 20 minutes, and flush it out. You have no idea if the fluid was exhausted after 2 minutes. You might have been soaking your lines in ineffective water for 18 minutes.
The "Purple" Advantage: With purple cleaner, you watch the glass at the bar.
- If it comes out Green, you know you need to soak longer or refresh the batch.
- If it comes out Purple, you have visual proof—scientific verification—that the line is sterile.
The Behavioral Economics: The "Psychology of Clean"
Rory Sutherland (Ogilvy) talks about the importance of "signalling." Line cleaning is invisible work. Your customers don't see you doing it.
But when you use Purple Cleaner, the process becomes visible. If a regular sees you pulling a pint of purple fluid through the tap, it signals Competence and Care. It tells them: "This place takes hygiene seriously."
Use the purple fluid as a marketing tool. Let the regulars see the effort.
The Safety Warning (Crucial Upgrade)
Here is the catch. Purple cleaners are not "soap." To achieve that colour-change reaction, they use a high concentration of Sodium Hydroxide (Caustic Soda) and Sodium Hypochlorite.
This fluid is aggressive. It dissolves organic matter. Your eyes are organic matter.
If you are going to switch to the "Pro-Grade" Purple stuff (which you must), you cannot wear your street clothes. You need to upgrade your armor.
1. The Eyes: No Excuses
A splash of clear cleaner stings. A splash of Purple Caustic can cause permanent corneal damage in seconds. You need sealed goggles. Not glasses. Goggles.
- The Expert Choice: Bolle Pilot Goggles. They are vented (so they don't fog in the cellar) but sealed against drips.

2. The Hands: The "Marigold" Myth
Do not use yellow kitchen gloves. They are too short, and caustic soda can degrade cheap rubber over time. You need Chemical Gauntlets (EN374 rated). They must cover your wrist and forearm so that when you lift the line cleaning bottle, drips don't run down your arm.

The Protocol
- Flush with Water: Push the beer out with water first.
- The Purple Push: Connect your Pressurized Cleaning Bottle filled with purple fluid.
- Watch the Tap: Open the tap. Watch the colour.
- Green? The line was dirty. Close the tap and soak for 20 mins.
- Purple? The line is clean.
- The Rinse: Flush thoroughly with water until the water tastes like water, not swimming pool.
The Verdict
Using clear cleaner is like driving with your eyes closed and hoping you don't crash. Using purple cleaner is driving with GPS. It tells you exactly where you are.
It costs a few pennies more per litre. But the peace of mind—and the guarantee of a perfect pint—is worth ten times that.
