Hi all.....

I recently read where Dawn Power Disolver works well for cleaning engines. The article was in Model Airplane magazine where it was
mentioned......the problem is.......the article ran in the last months issue, so I don't know how to go about using it. Can anyone help ?
I would like to know the procedure for doing this.

Thanks in advance

What is on or in the engine are you trying to clean? Like is it the crap on the outside or the crap on the inside? Are you taking the engine apart? Let me know and I'll see about helping you.

Thanks for the help in advance.....its the glow fuel crud on the outside. I was all ready to use trans fluid in the crock pot, but then I
heard about this. Any ideas on the easiest way to do this ????

Thanks

Btw, it's antifreeze, the old green toxic stuff (ethelyene glycol (sp)) you want in a crockpot to clean engines, not transmission fluid. The tranny fluid makes a great after run oil though.

yeah, the antifreeze stuff works well. I tested it on my tower 46. I put it in and cooked it on and off for a while and it worked really well. You don't actually NEED a crockpot, it acts as a catalyst. I left a Super tiger 75 in antifreeze for a couple of months, and that worked really well, could just rub off the baked on stuff. You can pick up a small crock pot for less than $10. One other thing, I would make sure that you clean out the antifreeze out of the engine. What I do is wipe off as much stuff as I can, then rinse off the rest with isopropyl alcohol (here comes the flamage), wait for it to dry, put drops of after run engine oil in it (I use marvel mystery oil) all over. I mean every where. All the open spots. Then I gas it up on a test stand and go for it. So far, its worked well for me.

Thanks for all the replys.......and yes.....I did mean anti-freeze (the green stuff) and not tranny fluid.......(could you tell I was in a hurry
when I posted this. I guess I am still alittle confused........so.......if I put the antifreeze in a crock pot on low and cook overnight, do I
put a cap on the carb to keep the antifreeze from getting IN the engine, or is it ok if it does ????? Like I said I also heard about the Dawn stuff to use....just don't know how to use it. Seems to me I wouldn't want that stuff inside the motor !!!!!!

Any more thoughts would greatly help.....I'm sick of looking at this dirty thing.....lol

I just did my TT PRO 46 overnight in a crockpot with Prestone. The engine was completely disassembled, since the rear bearing needed to be replaced anyway. I soaked the Crank case, muffler, crankshaft, and head. The rest (piston, liner, carb) I left out.

Came out looking fantastic. A light brushing with a cheap toothbrush to remove the remaining goo, rinsed with warm water, dried it, wiped internals with a little 3 in 1 oil until I get to reassemble it this weekend.

Can't see any reason to use any other method anymore.

I just soak the whole engine, generally, I remove the head and back cover, maybe even the front if it has it. I would probably go ahead and take the rest of the engine apaart, however I can never get the piston off. But yeah, if your just trying to get the outside, if you've got a little nerve, you could even take some lava abrasive soap and a tooth brush and go at it. I do that on the crap on the mufflers.

The PROPER way to do the crockpot cleaning is:

Disassemble the engine as far as you can. MINIMUM is removing the head, backplate AND CARB. Put all these parts, MINUS ANY GASKETS, O-RINGS, ETC, in the crockpot and have them covered with the anti-freeze. (The antifreeze can damage some types of gaskets and o-ring materials)

Put the crockpot on low and let "cook" overnite.
DO NOT USE THE CROCKPOT FOR FOOD AGAIN (the antifreeze gets into the pores of the crockpot and will poison any food cooked in it) AND DO THIS OUTSIDE !!! The fumes from the antifreeze will make you sick.

After "cooking" I thoroughly wash all the parts with dish soap and water and rinse well. I then put them in a 200 degree oven for about 20 - 30 minutes to completely dry them.

After removal from the oven (and after the parts have cooled off) lubricate WELL with after run oil, air tool oil, Marvel Mystery Oil and re-assemble the engine.

Take engine and run it on a test stand.
