Prochem – Coffee & Tannin Spotter

Prochem Coffee & Tannin Spotter is an advanced, ready-to-use acidic chemical treatment specially formulated to break down and eliminate stubborn brown or yellow spots caused by spilled beverages and organic matter. Unlike all-purpose spotters, it utilizes a combination of acidic cleaning agents, strong reducing agents, and surfactants to neutralize the alkaline nature of set tannins, coffee beans, and plant extracts, chemically altering the stain structure so it can be completely rinsed away.

Key Technical Specifications

• Form & Color: Clear, completely colorless liquid.
• Acidity Range: Highly acidic, running an RTU pH of 3.5 to 4.5 to reverse browning and neutralize residues.
• Scent Profile: Distinctive sulfurous aroma due to its reducing agents.
• Chemical Group: Concentrated acid-detergent blend with built-in reducing agents.
• Dilution Rule: Ready to Use (RTU); never dilute with water before spraying.
• Primary Target Surfaces: Formulated specifically for synthetic fiber carpets (nylon, polyester) and water-cleanable upholstery.

Target Stain Profiles

This specialist formula works exceptionally well on “browning” or organic spills, including:

• Tannin Spots: Brewed coffee, black tea, red or white wine, cola, beer, and dark fruit juices.
• Organic Discoloration: Water-marking rings, houseplant soil overflow, and aged berry juice.
• Alkaline & Bodily Fluids: Set-in urine spots, vomit, alkaline cleaning residues, and minor ink or dye bleeds.

Step-by-Step Professional Application Guide

1. Dye & Fabric Pre-Test: Apply a drop to a hidden patch of carpet to ensure the acid will not pull the base dye or shrink the backing.
2. Extraction Prep: Blot up fresh wet spills with a towel. Vacuum dry crust or loose soils first.
3. Zoned Spray Application: Spray directly onto the fibers. Avoid over-saturating the carpet backing.
4. Dwell Phase: Allow 2 to 5 minutes of dwell time so the reducers can break down the tannin molecules.
5. Rinse and Extract: Thoroughly extract the spot using clean water or a neutralizing rinse agent. Repeat for deep, old stains.

Safety and Logistics In Canada

• Personal Protection: Wear chemical-resistant gloves and safety glasses during application. Avoid breathing down the sulfur spray mist; always keep the room well-ventilated.
