psi for restaurant tile cleaning

[bahrahm]

how much water pressure do u use when u do restaurant tile cleaning? i did with 1200 psi (sx-12) with 230 F but it worked slow so i increased water pressure up to 1800 psi. it worked awesome. fast and clean well( no damage any grouts).

I usually run 1500-2200 or even a little more. Really helps move things along.

Wow, that's a lot of pressure. What type of heaters keep up with the pressure you guys are running? I want to get into more tile cleaning, but my Little Giant #3 heater only goes up to 600psi. So I've been using cold water @ 1,000-1,200psi. I know the heat will make it go sooo much faster. My TM pump gauge only goes to 1,000, so I use the Mytee WaterHog.

I usually use 1200, crank the heat up to 275 to maintain around 200. The video I just posted was @ 1200 psi, more dwell time no scrubbing of that tile at all.

I normally have mine around 900 to 1000 psi..and about 220 degrees....

as long as your chemical is doing its job..there is no reason to blow the grout out...
