It always removes gum completely. The only thing that can happen that the gum leaves prints on the surface. This print is caused by a reaction between the acids in the gum and the stone (most of the time comcrete). For sure gum is easier to remove in cold areas, the colder the better! Heat (enough) is in first the most imortant thing the pressure speeds up the operation.

Problem is that if the water gets out of the nozzle you will get a steam cone in stead of a nice and sharp spray line on to the surface. In this case heat will do no good because you can not "cut" the gums of the surface you have to cook them of this takes a long time.

In that c
 
In that case it is better to adjust temperature in such a way that you are just on boiling point so no steam but still water fraction comes out of the nozzle. <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:eek:ffice:eek:ffice" /><o:p></o:p>
If you can't adjust it to steam at all you need smaller nozzle sizes.<o:p></o:p>

So heat is the most important thing just under boiling point after this pressure.

I remember the baked on gum at the DMV in Vegas, just like the baked on gum here in Texas.

We tried heat as hot as 315 degrees and it did not clean the gum faster than 250 degrees or 200 degrees.

It seemed like the best results were from 180 to 250 degrees water, hotter did not do better and colder just took longer.

Sorry, I can't give you details on that. It is only sold including a license for the US or part of the US. We are currently looking at the US market to get more insight on chewing gum polution at communities, what they do about it and what the price rates are in the US.

Next to that we look at strong partners who are capable to develop the market in the US for pavementcleaning and chewing gum removal. Are youre cities free of gum?

I don't think any U.S. cities are "free of gum".
 
I wonder if anyone here in the US has bought one of those surface cleaning /gum removal machines, look like they do a good job.

If over boiling you have to use the correct nozzle, and be well over it too, to max its effectiveness
