[i:42d024ba9a]I just rescued a Allis crawler model M. The hose to the carb. was off so I thought I better check the air cleaner. The top looks like it has straw or something that looks like straw in it, the bottom has a rough steel wool in it. My question is can or should this be cleaned and how would you do it?[/i:42d024ba9a]

Yes, it needs to be periodically cleaned, a very commonly overlooked maintenance item.
Look at the canister, if it will come part, take it apart, dismantle it and clean the elements.
Some are difficult to separate.
If it's not in too bad condition, it can be soaked in diesel if it's oily, strong detergent (Purple Power) for dirt, and blown out. May take several treatments.
But if it's packed with years of neglect, it will have to come apart by whatever means. Then make the decision to save the mesh or replace it.

Most oil bath air cleaners are designed such that the mesh can be removed. If so, remove and clean or replace. Replacement mesh is available.
Do not neglect to inspect/clean the down tube. I have seen down tubes nearly closed off from accumulated oil soaked dust, and almost no one ever inspects the down tube.

Feguson TE20 tractors have updraught oil bath air cleaners .
The mesh is coarse steel and gets incredibly filthy , no manner of soaking or air blasting will clean them properly .
At the most the mesh will be held in by a perforated plate or bracket that is spot welded in a few places , drill these out and remove the mesh . The spot welds can be replaced by pop rivets or self tapping screws when reassembling .
The mesh itself can be very fragile , unroll it out on a board and clean it by soaking a short section at a time in a shallow bath of kerosene or some such solvent . If it's OK roll up carefully and refit . If it isn't good enough to put back you can substitute it with coarse stainless steel pot scourers , the soapless kind , pack them in loosely , they work just as well as the rolled mesh .
My 1952 Fergie had apple leaves , grass and enough grit to sand a table down inside its filter , all left after a week's soak in old petrol , I'm glad I pulled it apart .
Pictured here is the underside of the filter mesh and the retaining plate .

Not "should" but "must" be cleaned! No amount of soaking or magic will get the crud embedded in the middle and top of the
filtering element.
Charles in Australia is right. The mesh needs to be pulled out and cleaned or replaced. Some have screen mesh plates. You can buy
the mesh from YT's marketplace. The wire mesh plates can be cleaned in a parts washer. I've had some plugged with cotton lint and
have successfully burned the cotton lint off without hurting the mesh.

I cleaned one with full strength purple power. Put a 2" rubber stopper in the inlet, stood it upside down in a bucket and filled it up. Let it soak a couple days then flushed it out with hot water.

I soak mine in gas for a couple days - the mesh appears clean and allows air to pass through without issue. If the mesh has become so compacted with dirt that it can't be cleaned I'd be surprised that the engine even runs. That can be case if you are using "steel wool" and not an air cleaner mesh.
The mesh in the oil bath air cleaners I've seen is much heavier than any steel wool I've come across. If it has been destroyed through neglect it needs to be replaced buy a real replacement part.
