I have taken several apart for cleaning and was glad I did each time. It was a pain as I had to to cut the spot welds on the bottom spider to get the mesh out. This was on Farmall stuff. Other brands may be different. The one in the photo looks like it simply presses together.
The worst was on a 400 diesel. I had soaked it to clean it and finally decided to take it apart. I couldn't believe how much crud was in the upper third of the filter mesh. No amount of soaking would have cleaned it as there is no way to get any rinsing action up in there. It took some very strong solvents and mechanical scrubbing to get that one cleaned up.
The other bad offenders are tractors that have spent earlier days in the cotton fields and the filter is plugged with cotton lint. On those I have taken the mesh out, soaked it in mineral spirits and then set them on fire. The lint burns away cool enough to not hurt the mesh. There is no way to scrub or dissolve cotton lint off of the filtering mesh.
Sometimes it's better to buy new mesh and replace the old stuff. There was something about the one on the 400D but can't remember why I went to all the trouble on that one to save the original screens.
I believe that soaking the entire assembly may loosen a lot of crud but not get it rinsed out and actually make it easier for the engine to ingest that garbage once it's running again.
Another problem that I have found in this region is that if the tractor sat for any time with the tube between the carb and the filter off is that dirt dauber wasps will get in there and build nests in the top on the clean side. There is no way to get all the dirt knocked off and washed out other than complete tear down and washing.
