I cant recall seeing this subject before on a forum and one of todays jobs where i had no access to anything more than luke warm water made me wonder if there is an optimal temperature for pre spray?
In a majority of my jobs i use solutions micro splitters and when available apply it mixed with hot water at approx 60 degrees, this will obviously be considerably cooler when it hits the carpet but will heat benefit micro splitters performance when used as a prespray, if so what is the optimal temperature??
The job today was on a lightly soiled polyprop so cleaned up with ease regardless, so no problem in this case but any info on this subject would be appreciated.

Thanks Paul

Hot water dose make a big difference to any pre-spray.

Its a bit like washing your hands, much better results with hot water.

Hi guys

Remember the sections of the 'cleaning pie'

Reduce one section (in this case heat) and increase the others to compensate

Paul has made a good point regarding heat-loss between sprayer and carpet.

This is particularly the case with micro-splitters and other pre-treatments that are misted onto the carpet. The fine droplets can store very little kinetic energy and this is mostly lost in transit.

If anyone has any doubt, fill a sprayer with very hot water, set it to a fine mist and let someone spray you from a distance of 3 or 4 feet.

Good Idea John in this weather.

I have carried out tests with a laser guided remote thermometer, and yes, temperature drop between source and target is dramatic.

But even lukewarm is better than plain cold (think of the aforementioned hand washing)

So are you saying in the case of pre spray the hotter the better?

I've always mixed pre-spray with hottest water possible, except heat sensitive presprays (usually enzyme types).

Paul,

The hotter the better, subject to the heat tolerance of the chemical employed.

The point I was making is that if the temperature is not available, then the difference made will be much smaller than might be expected, especially when mist-spraying.

You could always heat it in your portable and spray it through your wand

You could always heat it in your portable and spray it through your wand

Then drain the portable, and flush out the solution line?

No!  The way to use the portable to supply the pre-spray is via one of the dedicated sprayers such as the Hydroforce (provided the pump can supply the required pressure). This is particularly applicable if you use water-only rinsing.

The exception is when using Ultimate Master, wich is designed to be used in this manner as pre-spray and extraction agent.
