Tiling over OSB with linoleum adhesive residue

I'm working on a bathroom remodel. The bathroom floor previously was linoleum glued directly to OSB. I have understood that tile over linoleum is not good, so I removed the linoleum the back/bottom of the linoleum, and most of the adhesive. I say most, because it is extremely difficult to get it all off. I plan on using Ditra as an underlayment/uncoupling membrane. I'm worried, however, that the thinset will not adhere to the osb with the glue residue on it. The OSB is in great shape - the house is only about 16 years old. Will a thinset stick? Schluter All Set says its suitable for OSB applications - but not sure about the adhesive. What options do I have? submitted by /u/StatisticianParty326 [link] [comments]
