So this one really got the best of me today. Yall give me some of your guru expert advice on how to have gotten better results for this one. So this was my process. Prevac, follow with hydroforce sprayer 4:1 using citrazolv all and high ph harvard chem prespray 12-13ph. Dwell then rinsed at 400 psi to get top layer broken up so it could penatrate. Spray again heavier. Hit with oreck bumped up to 700 psi. Follow in 2 more times of pre spray with more citrazolv all added at 800 psi. Used nearly 3/4 of a 5 quarter hydroforce sprayer of solution 
. 220-230 degrees at wand. What a bust lol. Keep in mind this one had never been cleaned in probably 20 years. To add to it parking lot is across the street. Building is 100 years old and conrete subfloor underneath is pretty bad uneven and I'm sure has no moisture barrier. 3 hours down the drain for 80 bucks. So glad it's like 2 mins from my house or I would have been pissed lol. The charge was original 100 which is my local minimum but I wasn't happy with results so I gave a discount.
