Expert Review and Insights
In my experience, many degreasers talk a good game but fall short on heavily carbonised fat. The Karcher RM 731 is different. It's a genuine workhorse that visibly melts away grime on extraction filters and fryer surrounds. Its ability to work with pressure washers makes deep cleaning far less of a chore and significantly more effective, a huge plus for busy kitchens.

- Real Power: It effortlessly lifts stubborn grease that has built up over time.
- Application Matters: Needs proper dilution and works best with mechanical action.
Case Study: Real Business, Real Results
A popular pizzeria in Glasgow was finding their end-of-day cleaning routine was becoming a real bottleneck. The build-up of oil and burnt-on food residue on their stainless steel pizza prep stations and oven hoods required intensive scrubbing, costing valuable staff hours.
"We switched to the Karcher RM 731, using it in a spray bottle for daily wipe-downs and with a machine for our weekly deep clean. The difference was night and day. The grease just lifts off, and our kitchen has never looked better. It has genuinely simplified our closing process."
Marco Bellini – Head Chef, Glasg-dough Pizzeria
The pizzeria successfully cut its nightly cleaning time for key equipment by over 25%, allowing staff to finish earlier and reducing overall labour costs.
Installation and Maintenance Guide
Setting It Up
- Always consult the label for correct dilution ratios depending on the soil level and application method.
- Wear appropriate PPE, including gloves and eye protection, when handling the concentrate.
- Before full application, test on a small, inconspicuous area to ensure surface compatibility.
- For best results with a pressure washer, use a detergent nozzle or setting for even distribution.
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 integrity.
- Keep a clear record of your COSHH (Control of Substances Hazardous to Health) data sheets.
- Do not mix with other cleaning chemicals to avoid dangerous reactions and ineffectiveness.
Frequently Asked Questions
Q: Can I use this on aluminium surfaces?
A: It's not recommended. This formula is optimised for robust surfaces like stainless steel and ceramics. Always test on a small patch if unsure.
Q: Does this product need to be diluted?
A: Yes, it is a concentrate. The dilution ratio depends on the level of soiling and whether you're using it manually or with a pressure washer. Always check the packaging for guidance.
Q: Is it safe to use on food preparation areas?
A: Yes, but it is crucial that any surface that will come into contact with food is thoroughly rinsed with fresh, clean water after cleaning to remove all chemical residue.
Q: Does the Karcher RM 731 work with cold water?
A: Absolutely. It is formulated to be effective in all temperature ranges, giving you flexibility whether you're using a hot or cold pressure washer, or just cold tap water.
Q: What does the 'asf' (easily separable) feature mean?
A: This means the solution separates from oil and water quickly. It's a key benefit for businesses using an oil separator, as it helps the separator work efficiently and aids in environmental compliance.
Q: Is this product scented?
A: No, this is a functional, professional cleaning solution and does not contain any added perfumes or fragrances, which is often preferred in a food environment.
Q: Is this suitable for mopping floors?
A: Only for very heavy-duty degreasing on suitable floor types like quarry tiles or sealed concrete. For daily, light cleaning, a dedicated floor cleaner would be more appropriate.
Q: What safety precautions are necessary?
A: We always recommend wearing protective gloves and eyewear when handling concentrated cleaning chemicals to prevent skin and eye irritation.

Explore more from KarcherWhy Being 'NTA Free' Is a Big Deal for Your Kitchen
You’ll see 'NTA Free' on the label, but what does that really mean for you? NTA (Nitrilotriacetic acid) is a powerful chemical agent that was once common in detergents. However, concerns have been raised about its environmental impact and potential health effects. A modern, NTA-free formula like the one in the Karcher RM 731 means you're getting a top-tier clean without relying on older, questionable ingredients. Think of it as choosing a high-performance engine that's also more fuel-efficient and has lower emissions. It's simply a smarter, more responsible choice that delivers the power you need while providing better peace of mind for you, your staff, and your environmental obligations.
Who Should Buy This?
