Case Study: Real Business, Real Results

A busy automotive service centre in Coventry was struggling to maintain a clean and  safe workshop floor. Years of oil, grease, and  coolant spills had left stubborn, slippery stains that standard cleaners couldn't shift, posing a real safety hazard for their mechanics.

"We'd almost given up on getting the floor back to its original state. We switched to the Karcher HX439 for our floor scrubber, and  the difference after the first pass was astonishing. It cut through grime we thought was a permanent feature of the workshop!"

David Chen – Workshop Manager

The centre saw a noticeable improvement in floor safety and  appearance, reducing their daily cleaning time by over 30%.

Installation and  Maintenance Guide

Setting It Up

  • Always consult the packaging for recommended dilution ratios for your specific task.
  • Wear appropriate PPE, such as gloves and  eye protection, when handling the concentrate.
  • Before cleaning an entire area, test the diluted solution on a small, inconspicuous patch of flooring.
  • Add the solution to your scrubber dryer's clean water tank or your mop bucket—never mix with other chemicals.

Keeping It Going

  • Store the container in a cool, dry place away from direct sunlight and  frost.
  • Ensure the cap is tightly sealed after each use to maintain the product's effectiveness.
  • Keep the Safety Data Sheet (SDS) accessible for your staff's reference.
  • Order your next container when you have around 25% left to avoid running out during a busy service.

Buying Guide: Choosing the Right Cleaning Chemical

Not sure which chemical is the right fit for your floors? Here are a few tips to help you choose the perfect cleaning solution for your business.

Match to Your Floor Type

Check that the chemical is safe for your specific flooring, whether it's vinyl, concrete, tile, or safety flooring, to avoid any damage.

Concentrate vs. Ready-to-Use

Concentrates like this one offer better long-term value but require accurate dilution. Ready-to-use is convenient but often costs more per clean.

Check the Eco-Credentials

Look for features like 'NTA-free' or biodegradable formulas if environmental impact is a key concern for your business.

Consider the Soil Level

Be realistic about your needs. A light-duty cleaner won't work in a garage, and  a heavy-duty degreaser is overkill for an office corridor.

Always Read the SDS

The Safety Data Sheet is essential. It provides crucial information on safe handling, storage, and  what to do in an emergency.

Think About Fragrance

A fresh scent is great for front-of-house areas, but a neutral or low-odour cleaner might be better for kitchens and  sensitive environments.

How ASF Technology Makes Disposal Greener

Ever wondered what 'Rapidly separates oil/water (asf)' actually means for your business? Think of an oil separator in your drainage system like a bouncer at a club, designed to keep oil and  water apart. This Karcher cleaner acts as a brilliant helper for that bouncer. When the dirty water from your floor scrubber enters the separator, the 'asf' technology encourages all the tiny oil and  grease particles to clump together quickly and  float to the top. This makes it incredibly easy for the separator to skim the oil off, preventing it from entering the main sewer system. It means easier compliance with water authority regulations and  a more responsible, eco-friendly cleaning process.

Who Should Buy This?

  • Logistics & Distribution Centres: Effortlessly removes forklift tyre marks and  daily grime from vast concrete or epoxy floors.
  • Industrial Workshops & Garages: The perfect commercial floor deep cleaning solution for cutting through stubborn oil, grease, and  fluid spills.
  • Large Commercial Kitchens: Keeps kitchen floors safe and  hygienic by dissolving built-up grease on non-slip safety flooring.
  • Supermarkets & Retail Outlets: Maintains a pristine, welcoming environment for customers by tackling high footfall scuffs and  stains.
