what psi

[Larry B]

What psi are you running to clean tile?

At what temp?


Thanks

1200psi for man-made, 600-800psi for stone. As much heat as you can get for man-made, 180-200ish for stone. If you can't get much heat, add some dwell or mix your chems a little hotter.

You have to be careful with both PSI and heat.


Too much of either will crack grout.


Better to let time and agitation do most of the work.



IMO

800-1000 at 240 degrees atm

I haven't heard of heat cracking grout unless maybe you're cleaning in the arctic circle. Too much psi can blow out grout. I regularly clean @ 1800psi and haven't blown out grout in 3.5 years. That doesn't mean I advocate cleaning at that psi, but I know what I'm dealing with so it doesn't bother me a bit. Some commercial kitchens I'll go up to 2500psi, but really, I don't recommend you guys do that.
