That's a good question. When an average chip comes out after 1 minute and is still wet, it looks great! Totally clean and nice saturation. But then the water dries and you can see they've faded as well. The oil brings them right back and they stay looking really healthy. So, in this case, perhaps it does.Okay, but you mention only color. Do you think the fading and the dryness go hand in hand? Maybe they do with TSP, I’m not sure. But I’ve cleaned chips with oxi that have faded (a fading never to be restored by oil) but not all dried out.
You leave a chip in there for 10 minutes and it's no dryer than than the 1 minute chip; but it's colors are messed up. Not even oil can bring it back correctly.
