I recently cleaned an area of offices, and hallway in the executive area of a clients building. It was a Commercial glue down. We used a portable extractor presprayed a traffic lane cleaner (not high high PH maybe 9ish) using a hf sprayer extracted using hot water. We were in a hurry because the staff that were having to babysit were going to end up after 5 o'clock and the faces were long. Anyhow the next morning one of the execs said what are those spots??. irregular roundish spots. He swears they weren't there before. I wasn't sure what he was looking at until it was pointed out. I sent someone up to checked them with a moisture meter and maybe found a little moisture on one of them but not on the rest. They didn't want me to try to do anything with the spots at the moment because they had big meetings and Company coming.
About 2 months later they call me and I set up a day to go back up there. to me the spots looked more visible so I thought maybe there was some soap residue resoiling or maybe wicking. I came through and recleaned it same way as before but slower. lots of rinsing and lots of dry vaccing. I would say no residue to speak of now for sure. When I left I couldn't see the spots but, a few days later they are calling me again. I haven't been back yet but I assume the spots are still there.
They seem to see these spots only in the hallway. I am beginning to wonder if the pattern of the carpet isn't showing darker patches in irregular patterns and for some reason they see it in the hallway.
This thing has got me nervous because I am sure they would have put some overpriced carpet in there exec. area along with all the overpriced furnishings. I don't want to end up with a claim, or an alienated customer that thinks I did something to their carpet. I will do a test to be sure, but I do not believe it is wool, just old fashioned oil loving oliefin.
What would you guys suggest I try first. As far as I know it has only once been cleaned with HWE the one time since it was installed 4-6 years ago. As far as I know it hasn't been brushed, or bonneted. They do have an in house jaitor though that may have done either.
How can spots magically appear after cleaning and then never go away? I can't see wicking being an issue, but I don't know what else can cause something to look different after it is cleaned??
