Removing non-cured silicone and grease from equipment and flooring
Keeping your equipment and flooring free from non-cured silicone and greases can be time-consuming as it is difficult to remove thoroughly.
Here we look at this problem in more detail and how CHELA’s professional products can help save you time and increase efficiency.
The problem with standard degreasers
If you have ever had difficulty getting rid of uncured silicones, greases and oils it could well be because you are using a bog-standard industry degreaser.
These alkaline based degreasers often have the right chemical technology which leads to poor cleaning standards and potential workplace hazards.
How can CHELA help you remove non-cured silicone?
We are the industry leader in this field and recommend CHELA Di-Aqua.
This will effectively emulsify silicone oils, greases and uncured elastomers as well as remove adhesive tape residues.
It has a specialist cleaning action that also quickly and efficiently removes ordinary oils, greases and soils. CHELA Di-Aqua has been formulated for the environment, using detergents that are biodegradable and phosphate free.
It contains no chlorinated, fluorinated, aromatic or hydrocarbon solvents. This product is both safer and more effective than conventional solvents.
We also stock a wide range of other sealant removal products, such as our handy Sealant Wipes. These come pre-wetted to remove sealant, paint and glue and can remove partially cured and uncured sealants. This includes silicone, polyurethane and polysulphides.

How do you remove mould spots from outside tiles or concrete quickly?
Getting rid of mould spots from outdoor tiles or concrete floors is essential to prevent floors becoming slippery and dangerous.
Here we look at this issue and some of the more efficient, time-saving ways to manage the process professionally and effectively.
The problem with mould spots
Mould, mildew, lichen, moss and algae can all grow on outdoor surfaces, causing an unsightly looking mess.
However, on a more serious level they also increase the risk of slips, falls and injury and can even cause long-term damage to the flooring.
Eating into your bottom line
For building contractors, removing these problems can be a time-consuming process. This means more time spent on site and higher labour costs.
Unfortunately, many of the products you find on the market are designed and manufactured for the domestic retail market. These products are based on biotechnology, and can take time to show results.
While these are fine for remove some mildew from an outside patio area, they don’t give busy contractors the results they need fast enough.
This is a rapid acting cleaner that has been designed specifically for heavy-duty use on brick, stone and other exterior surfaces.
It washes off moss, algae, general biomass and all organic growth and can even be used on smooth surfaces.
It’s economical, easy-to-use and fast acting. A professional product for the construction and plumbing industry.

How to use fewer chlorinated products in the food and beverage industry
Chlorine is widely used in the food and beverage industry but comes with a number of significant drawbacks.
Here we look at what these are and investigate some of the smarter alternatives for you here on our website.
Is chlorine overused in the food and beverage industry?
Chlorine compounds are widely used to disinfect equipment and worksurfaces. Although it is a very cost-effective method, it comes with a number of problems.
The bulk of chlorinated products on the market offer limited performance. Not only do they take longer to get the job done, but they also increase the risk of hazards in the workplace, for both the user and the wider environment.
But how do you cut through the grease and grime on an industrial scale in a way that’s both time efficient and cost effective?
How can CHELA help reduce the amount of chlorine in your workplace?
CHELA Code 100 BALANCE is a powerful and highly effective alternative to chlorine and glycol-ether based cleaning products.
This professional grade product has been carefully formulated and contains a blend of non-ionic detergents and emulsifiers designed for maximum performance.

Graffiti; how do you remove it without damaging the building?
There are few things more that are more irritating than having to remove graffiti from your walls, but it’s even worse when your best efforts end up doing more damage in the long run.
Here we look at this problem and show you how to approach graffiti removal in a way that preserves your façade’s long-term integrity.
How much does graffiti removal cost?
Just in London alone, scrubbing graffiti off walls is estimated to cost well over £100 million each year.
Although some might see it as art, this is an awful lot of tax money that could be spent elsewhere.
To make matters worse, this figure only accounts for the cost of removal. It doesn’t consider the cost of long-term structural damage that graffiti can cause.
The problem with graffiti removal
The biggest problem many councils and institutions have is that most anti-graffiti removers are not water permeable.
Non-water permeable surface coatings do not allow the underlying surface to breathe, which over time causes damp and structural building issues.
How can CHELA help with graffiti removal?
We make EliteGuard G1, a unique high-performance protection system designed especially for porous and polished surfaces which are subject to graffiti attack.
It also works just as well against weathering, UV degradation and general soiling.
It reacts chemically to become part of the surface, giving it permanent protection whilst allowing the underlying surface to breathe.
EliteGuard G1 is a solvent-borne treatment that gives hydrophobic and lipophobic properties that are extremely easy to clean and maintain. Even on the most challenging surfaces.

Railway dust; removing the industrial fallout from exterior rolling stock
Railway dust, also known as brake dust or industrial fallout, is an ongoing issue for anyone concerned with the smooth maintenance of railways and rolling stock.
Here we discuss these fine metal particulates and how CHELA helps rail operators manage this persistent menace.
What is brake dust?
When a train’s brake pad rubs against the rotor, and the wheels against the rails, fine particles are produced, known as metal particulates. This process creates the railway dust that causes iron stain.
How is it produced?
All vehicles produce their own variant. However, the vast, industrial nature of railways and the safety considerations of transporting huge numbers of people each year, makes the efficient management of brake dust an on-going problem across the railway industry.
What problems can it cause?
The problem is much more than cosmetic. If left untreated, the fine particles will build up over time corroding copper solder joins and electric circuits. Furthermore, the build-up can trap moisture. This will increase the effects of corrosion and can lead to a general deterioration of rolling stock.
Is break dust dangerous for humans?
There are health issues surrounding the inhalation of break dust, and many reports that it can lead to terminal illnesses such as cancer. As such, we strongly recommend a structured and on-going programme of maintenance to ensure the removal of iron stain from all rolling stock.
How can CHELA help with iron stain removal?
CHELA supplies a number of leading rail companies with its specialist iron stain cleaning solution Eurowash ISR SheenPlus.
The product has been especially designed to remove ingrained iron stain either manually or with the use of automatic ash equipment.
It has been carefully tested and assessed by ESG Scientifics, the UK’s leading provider of testing, inspection and compliance services. We are pleased to say that it consistently outperforms other industry-standard acid products.
As well as dealing thoroughly and effectively with the issue of brake dust and iron stain, Eurowash ISR SheenPlus has also been designed to leave a high gloss sheen on all rolling stock.
This repels soiling and ensures high presentation levels, whilst also reducing cleaning times.
We have designed the product to the highest specification, making it safe to use across all rolling stock exteriors.

TNT: addressing the degradation of fleet paints and materials caused by detergents
Part of the Fisher Darville Group of companies, Chela Ltd was established in 1988 and is a UK manufacturer of innovative specialised industrial cleaning chemicals and technical solutions. Serving the UK, Europe and the rest of the world, Chela Ltd specialises in industrial cleaning solutions for all mass transport industries such as bus, rail, tram and coach.
A primary objective of Chela Ltd is to manufacture specialised high performance detergents using safer raw materials. Chela Ltd manufacturing operations are executed in-line with strict ISO 9001/14001 guidelines.
Chela Ltd provides industry approved product ranges, and was awarded the Green Apple award in 2014 for engineering and manufacturing.
This case study focuses on the challenge faced by Paul Crowley (FCILT MCIPS, Procurement Manager of TNT), who was concerned that the use of a large number of vehicle cleaning detergents on TNT sites and fleets would cause degradation of the paint and materials of the fleet as well as environmental damage. There was also a number of complaints from drivers about the cleanliness of the fleet. Furthermore, Mr Crowley planned to rationalise the number of contractors cleaning the fleet.
Thanks to Chela Ltd, the number of interior and exterior cleaning solutions used on TNT owned vehicles was reduced from 22 down to 1: dramatically reducing the risk of environmental damage, saving time and costs.
In 2015, Paul Crowley of TNT contacted Chela Ltd to discuss the type of vehicle cleaning detergents that the TNT contractors were using to clean TNT owned vehicles. TNT employed a large number of contract vehicle cleaning contractors across the UK to clean their fleet, and they in turn used a large number of vehicle cleaning detergents of unknown quality and performance. Mr Crowley was concerned that the use of vehicle cleaning detergents on TNT sites and fleets could cause degradation of the paint and materials of the fleet and cause environmental damage. Having dealt with Chela whilst working for Alstom Transport UK Ltd, Mr Crowley knew that Chela’s technical ability support would be invaluable.
TNT Express is an international courier delivery services company founded in Australia in 1946. The firm, who has headquarters in Hoofddorp, Netherlands, has fully owned operations in 61 countries and delivers documents, parcels and pieces of freight to over 200 countries.
The starting point was an evaluation by Chela of the SDS (safety data sheet) of all the existing vehicle cleaning detergents. It soon became apparent that a number did not comply with legislation and also contained materials that had been classified as hazardous to health and the environment.
An inspection of the material safety data sheets of the 22 cleaning chemicals in-use revealed that 14 out of 22 products did not fit in the recommended pH range:
Testing and inspection specialist ESG (Environmental Scientifics Group) recommend a pH range of 6-10 to avoid potential environmental issues and to ensure best practise in relation to corrosion.
3M Vinyl Manufacturer Instructions – Maintenance and Cleaning: The cleaner must be wet, non-abrasive, without strong solvents, and have a pH value between 3 and 11 (neither strongly acidic nor strongly alkaline) (ref. 3M product Bulletin IJ180/180C, Release UKH, Effective June 2010)
Moreover, the Product Ingredients Analysis revealed that the products in use contained dangerous and non-biodegradable Raw Materials:
Nitrilo Triacetate Acid “NTA”: possible cancer causing properties
It was also revealed upon inspection that not all hazards were properly listed on the material data sheets.
A closer look at the substrate compatibility further illustrates the need to revise the current mix of products-in-use:
As seen above, the products in-use prove to be harmful to both the vehicles and the environment, causing damage to many areas of the vehicle due to the highly alkaline and highly acidic nature of the chemicals.
Unlike the UK Rail Industry where all chemicals used are monitored and independently tested, the UK Fleet Industry does not have specific guidelines in relation to best practice chemical manufacture, and no independent testing house to provide analysis in relation to potential for corrosion. As a result, highly hazardous and corrosive raw materials are in use providing the potential for health, environmental and substrate compatibility issues.
After extensive use of Eurowash 1000 Plus, the TNT fleet showed considerable improvement in cleanliness and the drivers commented on the levels of gloss, one of whom shot the picture on the right.
It performed exceptionally well: TNT approved the product for use on their vehicles, and all their contractors had to comply. The number of contractors was reduced from 20 to 2 approved contractors, the number of products used reduced from 22 to 1.
TNT are now using Chela’s FleetClean Plus through the automatic wash.
Chela automatic wash products, FleetClean Plus and more now Kirton approved:
Kirton provide water treatment and filtration systems, ranging from seawater desalination to fully installed MBR systems. The systems are used in automatic vehicle wash systems.
Chela Ltd put forward an alternative product to TNT: Eurowash 1000 Plus.
Eurowash 1000 Plus is a foaming, caustic-free transport cleaner to remove traffic film from trains, cars, lorries, vans, buses, coaches as well as street furniture. It uses biodegradable surfactants and modern complexing agents (NTA and EDTA free), and has a high dilution rate, making it ecological and economical to use.
This product, used in the rail industry, has extensive materials compatibility testing and is classified as a low hazard. Eurowash 1000 Plus was specifically designed to provide the highest levels of presentation whilst eradicating the potential for long term substrate compatibility issues and potential negative impacts on the environment. Eurowash 1000 Plus holds an independent analysis certificate (4-Rail Services) and does not contain any of the following raw materials: NTA, phosphates, caustic.
