could this damage disk?

I have been using isopropyl alcohol with a blue microfibre cloth (like one for cleaning sunglasses)... been using it periodically for a couple of months.

was using it today and then noticed when i switch to paper towel to clean the containers and spray with iso alcohol that some faint blue ink was ending up where my thumb was... so obviously the blue microfibre cloth is starting to leach the ink slightly... i am not using this cloth anymore but wanted to know if this could have done anything to the dvd's? from what i can see it hasnt left any blue tint on the disks... yet it was ending up on my thumb...

Possibly. I use 99% isopropyl to remove Sharpie ink from DVDs, so it is a fair solvent for some dyes. I suspect the small amount of blue dye that your cloth picked up wouldn't hurt anything and probably never soaked into the disc. But I would use a white microfiber cloth or just a soft white paper towel from now on. Isopropyl itself doesn't seem to damage the polycarbonate layers of the disc, but that doesn't seem to be what you are asking.

so is there any point in rewiping them using some soft paper towel... best thing i have is soft toilet paper.
