Large quantities of mud and animal waste that are not directly incrusted into the surface are efficiently cleaned with higher water flow levels, even at pressure rates of 170-190 bar. ` Pressure should be used more when dirt is dried and incrusted. Tests have shown that for loose mud and animal waste, an increase of 60% in water flow at same pressure levels reduced cleaning time by 69%. This in turn reduces the total consumption of water and electricity - thus reducing the cost of cleaning.

Temperature levels of up to 55 C may be used especially on metallic surfaces to add a certain degreasing effect. Use of temperature may allow a reduction in water flow and pressure.

Soaking with detergents will reduce overall cleaning time by softening dried mud and animal waste.

Specific accessories such as rotary lances will reduce cleaning time by cutting through layers of dried dirt.

Chewing gum cleaning is a very intensive task.

Although often best solved with steam cleaners, brass brushes and detergent, chewing gum may also be removed by the use of very hot water (80-90C), a detergent + the use of a special accessory such as Powerscrub floor cleaner or Powerspeed rotary lance to increase the cleaning effect. To efficiently clean chewing gum, minimum pressure and flows of 200 bar and 1000 l/h are recommended.

Protein rich dirt tends to be very loose dirt in large quantities (blood, fish scales and parts, small particles of meat…).
The dirt is rarely ingrained into the surface and therefore does not usually need particularly high pressure levels to be cleaned.
The large quantity of loose waste is best removed therefore with high levels of water flow. Hot water to a certain level will increase the cleaning effect of the surface.

Maximum temperature for cleaning of protein rich waste is 56-60 C. Above this temperature, the cleaning effect will be inversed and the waste will re-cook and stick to surfaces.

Food industry standard alcaline detergents wil increase the overall cleaning result and will also better prepare surfaces for disinfection.

Cleaning of oil and grease from metallic surfaces is an application that requires the use of hot water and/or detergent in order to reduce cleaning time. Even at high performance levels such as 250 bar and 1000 l/h, cold water cleaning is very ineffective.
Cleaning efficiency at 180 bar and 800 l/h is more than 4 times more efficient with 60 C water than with cold water.
The only way to increase efficiency for this application when using cold water is to also use a strong alcaline detergent.

If required to use cold water without detergent, then the most efficient performance level is 200-250 bar and 1000 l/h. Lower pressure levels with higher water flows are still less efficient.

There is almost no efficiency increase when increasing temperature from 60 C to 90 C. The decrease in cleaning time (labour costs etc) will not sufficient to compensate for the increase in fuel consumption and costs.

60 C water temperature, minimum 180 bar and 800 l/h + an alcaline detergent is the optimal cleaning method offering the highest efficiency and quickest cleaning method.

Cleaning of graffiti requires special accessories in order to correctly accomplish the task.

Cleaning may be done with cold water and in association with a WET SOFTBLASTING type equipment. This method adds a low agressive bicarbonate and silicium based powder to the water flow. It is sufficiently abrasive to remove graffiti yet will not damage surfaces such as stone, glass etc.

The powder is a salt and therefore a test area should be made. Stone surfaces should be flushed and rinsed following cleaning. The powder itself is soluble and harmless.

Dried concrete stains require higher levels of pressure at medium to high water flow rates to blast away the tough dirt from stone or metallic surfaces.
Cleaning time will be reduced as overall performance and power increases but will not be affected by water temperature.
Privilege cold water cleaners with pressures in excess of 200 bar and flow in excess of 1000 l/h for the toughest tasks in order to get them done quickly and efficiently.

Acidic detergents may improve cleaning efficiency especially on metallic surfaces.

Rotary jet lances will reduce cleaning time by increasing the impact of the water jet against the tough concrete dirt.

Light dirt and sand can be easily cleaned from all surfaces even with relatively low performances. Whereas higher pressure levels may damage surfaces - cutting into areas between paving stones for example - higher water flow levels are ideal for flushing away the very loose dirt.

Cold water cleaning tends to be just as efficient as hot water cleaning. There is no significant increase in cleaning efficiency at higher temperatures.

Specific accessories such as Powerscrub floor cleaners or rotary jet lances will increase cleaning efficiency by increasing the surface area. The Powerspeed rotary lance can reduce cleaning time by up to 30%. A Ø500mm floorcleaner accessory can reduce cleaning time by up to 75% compared to a normal lance and nozzle attachment.

The most effective method for cleaning oil and grease from vehicle bodywork is to use a combination of hot water at 60 C, a detergent such as an alcaline shampoo at average pressure and water flow levels. By using detergent and warm water, pressure does not need to exceed 180 bar for a water flow of max 800 l/h. Lower pressure and flow levels will also protect the bodywork surfaces from damage. Note that a temperature of 60 C without detergent is 20% less effective than with 60C with detergent.

If detergent should not be used, similar cleaning effect can be obtained at same pressure levels by heating the water up to 90 C.

In the absence of hot water, the cleaning effect will come essentially from an increase in the water flow. 180 bar and 1700 l/h with cold water offers similar cleaning efficiency as 180 bar, 800 l/h with 90 C.

If using cold water only and no detergent, the use of a specialised accessory such as a brush can increase relative cleaning efficiency by up to 200%

Medium pressure/flow + detergent + 60 C water temperature = reduction of cleaning time by up to 4 times compared to medium pressure/flow with cold water

Medium pressure/flow + 60 C water temperature = same cleaning effect as medium pressure/flow + detergent + cold water

Medium pressure/flow + 90 C water temperature = same cleaning effect as medium pressure/flow + detergent + 60 C water temperature

Traffic film and pollution is not as stubborn to remove from vehicle bodywork as oil and grease. Reasonable cleaning effect can be obtained by use of medium pressure/water flow and cold water.
However, the most effective method is 60C water at medium pressure and flow and with use of alcaline detergent.This method will be 2 times quicker than using cold water at same pressure and flow levels. It will also be 10-15% quicker than using cold water at 250 bar and 1000 l/h and will also protect the surface to be cleaned.
Increasing temperature from 60 C to 90 C gives a 10-15% increase in cleaning efficiency - but does increase fuel consumption considerably. Depending on cost of labour vs cost of fuel, it may be recommended to remain with 60 C cleaning temperature.

Use of detergent with cold water increases cleaning efficiency by 100% (reduces cleaning time by half potentially)

Use of an accessory such as a brush increases cleaning efficiency on cold water by 50%

At 180 bar and 800 l/h, increasing temperature from cold water to 60 C will decrease cleaning time by approx 40-50%

Increasing pressure and flow from 180 bar, 800 l/h to 250 bar and 1000 l/h will also decrease cleaning time by approx 40% but may risk damaging surfaces

At 180 bar, 800 l/h use of detergent and 60 C water will decrease cleaning time by 2,5 - 3 times compared to same pressure and flow with cold water.

Cleaning of oil and grease from metallic surfaces is an application that requires the use of hot water and/or detergent in order to reduce cleaning time. Even at high performance levels such as 250 bar and 1000 l/h, cold water cleaning is very ineffective.

Cleaning of rim dirt is possible with cold water cleaners but at higher performance levels such as 250 bar, 1000 l/h or 180 bar and 1700 l/h. Lower levels of cold water performance are not efficient and will not obtain a good cleaning result even if cleaning time is increased.

At lower performance levels, hot water is required in order to reach good cleaning efficiency. Increasing temperature from cold water to 60 C will reduce cleaning time by at least 50% even at lower pressure and flow rates. At 180 bar and 800 l/h cleaning efficiency increases by up to 20 times !

Increasing cleaning temperature from 60 C to 90 C increases efficiency by 50% at same pressure and flow rates

Most efficient cleaning method is to use 60 C water + alcaline detergent - even at lower pressure and flow levels

Accessories such as brushes also increase cleaning efficiency considerably.

Protein rich dirt tends to be very loose dirt in large quantities (blood, fish scales and parts, small particles of meat…).
The dirt is rarely ingrained into the surface and therefore does not usually need particularly high pressure levels to be cleaned.
The large quantity of loose waste is best removed therefore with high levels of water flow. Hot water to a certain level will increase the cleaning effect of the surface.

Maximum temperature for cleaning of protein rich waste is 56-60 C. Above this temperature, the cleaning effect will be inversed and the waste will re-cook and stick to surfaces.

Food industry standard alcaline detergents wil increase the overall cleaning result and will also better prepare surfaces for disinfection.

Tests have shown that for loose mud and animal waste, an increase of 60% in water flow at same pressure levels reduced cleaning time by 69%. This in turn reduces the total consumption of water and electricity - thus reducing the cost of cleaning.

Temperature levels of up to 55 C may be used especially on metallic surfaces to add a certain degreasing effect. Use of temperature may allow a reduction in water flow and pressure.

Soaking with detergents will reduce overall cleaning time by softening dried mud and animal waste.

Cleaning of graffiti requires special accessories in order to correctly accomplish the task.

Cleaning may be done with cold water and in association with a WET SOFTBLASTING type equipment. This method adds a low agressive bicarbonate and silicium based powder to the water flow. It is sufficiently abrasive to remove graffiti yet will not damage surfaces such as stone, glass etc.

The powder is a salt and therefore a test area should be made. Stone surfaces should be flushed and rinsed following cleaning. The powder itself is soluble and harmless.

Cleaning of rust requires special accessories in order to correctly accomplish the task.

Cleaning may be done with cold water and in association with a WET SANDBLASTING type equipment. This method adds a QUARTZ SAND to the water flow. It is abrasive enough to remove rust quickly and efficiently from any metal surfaces.

Dried concrete stains require higher levels of pressure at medium to high water flow rates to blast away the tough dirt from stone or metallic surfaces.
Cleaning time will be reduced as overall performance and power increases but will not be affected by water temperature.
Privilege cold water cleaners with pressures in excess of 200 bar and flow in excess of 1000 l/h for the toughest tasks in order to get them done quickly and efficiently.

Acidic detergents may improve cleaning efficiency especially on metallic surfaces.

Rotary jet lances will reduce cleaning time by increasing the impact of the water jet against the tough concrete dirt.
