Diesel Exhaust Residue

[Jim Jacobson]

Bought a 4740 last spring w/a front mount snow blower. It was my first diesel. There is a pretty significant build up of exhaust gas residue all over the back of the blower - and elsewhere.

Removed the blower the other day and thought I'd remove the residue with the power washer - no luck. Tried degreaser - no luck. Chem-12 (a very strong solvent) - no luck. Ended up using Chem 12 with a rag and it comes off okay, but it's impossible to get around the nuts/bolts and in tight corners. What works?

What do you use? Ideally, I'd like something to spray on and wash off with the power washer w/out elbow grease, but that may not be feasible. Any ideas?

Wildfire. If you want to built an upright stack "kit" for everyone, or just for me, such as you built for yourself - I'll buy one.

I use a mix of Windex and Spray 9. Soak it down, let it sit for 5 minutes and then hit it with the pressure washer. Might have to do it twice to get it all off.

Spray 9 is a product I am not familiar with. Assume it's available at the market or Home Depot/Lowe's. Yes/No?

I think Spray 9 is more or less 409. If you get all the black off there put a good coat of wax on it. That might make it easier to clean next time.

Its available at a lot of industrial supply stores and also at Walmart here in Canada. Something else that works real good is WD40. Same thing, spray it on, let it sit for awhile then hit it with the pressure washer.

Spray 9 has been around here at least since the 70's. Could be it's not widely distributed in the more Western time zones.

I have good luck with was called Castrol Super Clean. I think it's now called Purple Power and not sure if it is associated with Castrol now. It's pretty much a purple Spray Nine and I get it at KMart.

My grandad was getting set up to rep for a pressure washer manufacturer back in the mid-60's before thay became so commonplace. I remember him saying that if you really want to get something clean, you need to take a brush or rag to it. He said it didn't matter if you had enough pressure to blow the paint off, there would be a film left behind. Fast forward 50 years and guess what. To get the diesel black off my tractor it takes the purple stuff and a scrub brush.

I use simple green myself I figure if it works on mining equipment then it should work on everything,, just MHO

I use 409 and it seems to work well. My power washer wouldn't take it off either.

Try using WD-40 with one of their fog-nozzle spray cans. Followed by any good grease-cutting cleaner. And maybe followed by pressure washing. Sometimes mine after setting a while will hose right off.
