We installed Cyril Oak through out our house a little over a year ago. Im having a terrible time keeping it clean. Dirt gets in the grain pattern which makes it look way darker than when it was new. The only way I’ve have found to clean it is scrubbing with a bleach product. I ordered some of the floor cleaner that Cortec recommended and that cleaned the floor but not the grain pattern. I’ve talked to my housekeeper about changing her pads more oven. I think they were just pushing around dirt. Im so frustrated and disappointed in these floors. They looked beautiful while they were new and after spending 4 hours on my hands and knees scrubbing them. Has anyone else had this issue? And if so what solution have you come up with? I called the Flooring retailer who also did the installation and they recommended trying the diluted bleach cleaner. UGH!

Those look to be a mechanical 'roller' pattern. They are interfering with the pattern (photo). Go ahead and use sticky notes to tag each plank that has this pattern. Then go back and analyze whether or not it is the same PATTERNED plank. In theory it should be a random occurrence found on different planks. That would indicate it is a manufacturing issue. If it happens ONLY on one specific type of plank, then it *might be part of the pattern.

If you put manila in the search bar - you should get posts with that word. It doesn't always work but here's one with several photos of different installations. It looks really nice. https://www.houzz.com/discussions/5145335/manila-oak-cortec-photos-needed#n=31

No to top right sample....too dark and appears to have grey tones that do not compliment your existing cabinets. I think either of the other 2 samples look good.
