Why the need for such heat as steam. Ive only been cleaning tile and grout for a short time, but am getting plenty of referrals and great results on floors from Ceramic, Limestone, Travertine and Porcelaine. I am only using a plain hardly hot water rinse as the prespray and agitation does all the work of softening the grease and grime. Any stubborn build up of grease in the grout that hasnt been removed first time, is easily removed with just a second spray and agitation.
The other thing to bear in mind, is that the biggest asset in cleaning tile and grout is pressure, but the more absorbant the stone the less pressure you use
i.e. 1200 - 1500 psi for Ceramic etc but down to 800 psi for Limestone and Clay. Any higher for the latter can force the water right through the stone.
With that in mind the hotter the rinse the more absorbant it becomes, so surely, if using a really hot rinse it would be neccesary to reduce pressure.
Since pressure is a vital ingrediant, that would be defeating the object, even thought it could be argued that the extra temps would compensate for the lesser pressure - I cant see the point of changing the process when pressure will do the job in the first place. Or perhaps I am completely wrong?
