Ed Huntress wrote: What do you think of this "stuff" for cleaning the grunge out of a two-stroke expansion chamber? Castor oil is great for bearing life, but kinda messy in the exhaust... thanks for any suggestions. I doubt if it would do much, Bill. This is straight lye, with goop in it to keep it from sliding off of surfaces. It will saponify fats and oils, and it will attack some polymers and proteins (like the ones in your body cells), but it won't touch carbon. If the problem is partially-burned castor oil with some carbon mixed in, it might work. But, chemically, it's no different from "heavy duty" version of Easy-Off oven cleaner. You might try that first. It's less hassle for small projects. I've never had much luck finding a chemical way to get carbon out of an engine. There supposedly is some treatment but I can't remember what it is, nor have I tried it. When I did it, I used scrapers. Ugh. Consider the nature of the deposit - thermally polymerised vegetable oil + carbon. If it was a drying oil (e.g. boiled linseed oil) + carbon black it would be a paint so for easy decoking, use paint stripper. Obviously don't use an alkali (caustic) stripper on aluminium parts, but dichloromethane (methylene chloride) based ones are safe on all metals found in an engine. Wash off any residue with methylated spirits (or if you used an alkali stripper just with water). CAUTION: It will attack seals, gaskets and of course paint! The only notable problem is that plastic toothbrushes don't last long in contact with dichloromethane based strippers, which is a pity as they are ideal for cleaning ring grooves, round valve seats etc. Tried the oven cleaner already, not so great. Sandblast would be interesting, but the shape of the pipe makes it impossible to really get inside with a normal nozzle. I'm actually desperate enough to be thinking of making a high velocity water jet with sand entrainment to try and scrape the gunk off "around the corner" of the chamber. Right now, I can get a reasonable cleanout only if I'm willing to spend hours fussing with it, and getting pretty grubby in the process. Must be a better way... bill Yeah, well, good luck. If you find something that works, let us know. I don't have to de-coke old British engine cylinder heads anymore, but it may be useful for something. d8-) -- Ed Huntress "Extrude-hone" comes to mind, forcing an abrasive paste/slury through the inaccessible passages. Perhaps that will spark some DIY ideas... I've seen a marine engineer (big ships!) burn out the carbon from a bronze exhaust system off a launch with a Stuart Turner two stroke engine - remove the exhaust from the boat, remove all the lagging, pour a cup full of petrol down it and shake well, build a bonfire round the whole exhaust and as soon as the flames coming out the far end died away, hook up a vacuum cleaner on blow! The result was an absolute inferno out of the manifold end and a dull red glow from the pipe. Apparently the trick is to rake the bonfire away from the exhaust once you have the glow and restrict the air supply as well if that doesn't control it as you DON'T want a BRIGHT red glow ;-) It actually took something like fifteen minutes to get the glow most of the way down the exhaust, at which point the engineer commented that it was now done, and he'd just let the bonfire burn out and it would be ready to reinstall the next day and it was also annealed as a side benefit! I've never had the need or desire to try it myself . . . . YMMV! -- Ian Malcolm. London, ENGLAND.

I get nothing but 'deer in the headlights' looks when I ask about 'naptha' at the same darned stores where I used to buy gallons of the stuff for ~$7.00 *then ~$9.00 then ~ $14.95. Even the Pro paint store clerks now act like they never sold the stuff! *What the heck? Try Wal-Mart. Last year I got a gallon there.

I didn't look too deeply, but what I found is that the basic law cuts VOC-containing liquid container size down to a maximum of one quart, to avoid commercial use. I guess it sounded like a good idea to them at the time. But in the L.A. area it is against the law to sell gasoline powered lawn mowers.

Did you take a good look at the contents? Yes. This one is 75% - 80% trisodium phosphate http://www.savogran.com/Information/TSP_MS.pdf It works for brush-type rust-removal, which I use a lot: http://www.metalworking.com/Dropbox/...es/E-CLEAN.TXT I've run into this for years. Few retailers carry it; I don't know exactly how the law reads. My first choice usually is the local Sherwin-Williams store. The last time I bought there it was 100% TSP. But I was in Home Despot the other day and thought to pick some up. I started to buy a box clearly labeled TSP, but in the fine print it said that it was actually Sodium Carbonate. I do not think you can buy detergents in N.Y. with phosphates. You can't buy detergents with them here in NJ, either. Or in Illinois. I tipped my mother-in-law to buy some and to add two tablespoons to her laundry, after she complained that the new detergents weren't getting things as clean as they used to. That's the main reason I run out of it every once in a while. We have a real algae problem in NJ, from runoff, and I'm told that phosphates actually are the bigger problem, over nitrates. Since they've taken it out of most consumer products, the algae problem in the Delaware River supposedly is much lower. As long as TSP is sold in dull-looking boxes in big paint departments, it's unlikely we'll see much problem with its overuse. -- Ed Huntress "When shopping for household chemicals, look for the skull and crossbones." -- Ed Huntress |

Gunner "As physicists now know, there is some nonzero probability that any object will, through quantum effects, tunnel from the workbench in your shop to Floyds Knobs, Indiana (unless your shop is already in Indiana, in which case the object will tunnel to Trotters, North Dakota). The smaller mass of the object, the higher the probability. Therefore, disassembled parts, particularly small ones, of machines disappear much faster than assembled machines."

Hmm, the trio is Experian, Equifax, and TransUnion. I thought TRS was in there somewhere. Nah. Nothing legit about them. Just a chip off the old acorn, wot? Suckage. Perhaps it's time for everyone who uses Amazon to have a word with them about their colleagues. Turns out Amazon is not the only infected outlet. I read one story about how TRS got transaction information from Walmart, too. http://www.complaintsboard.com/compl...es-c10962.html I guess it is safe to assume that TRS can do a man-in-the-middle attack on *any* transaction, even writing a check *in the store*. I sure am glad there is a video camera at each intersection to catch crime. --Winston |

Castor oil is great for bearing life, but kinda messy in the exhaust... thanks for any suggestions. I doubt if it would do much, Bill. This is straight lye, with goop in it to keep it from sliding off of surfaces. It will saponify fats and oils, and it will attack some polymers and proteins (like the ones in your body cells), but it won't touch carbon. If the problem is partially-burned castor oil with some carbon mixed in, it might work. But, chemically, it's no different from "heavy duty" version of Easy-Off oven cleaner. You might try that first. It's less hassle for small projects. I've never had much luck finding a chemical way to get carbon out of an engine. There supposedly is some treatment but I can't remember what it is, nor have I tried it. When I did it, I used scrapers. Ugh. Consider the nature of the deposit - thermally polymerised vegetable oil + carbon. If it was a drying oil (e.g. boiled linseed oil) + carbon black it would be a paint so for easy decoking, use paint stripper. Obviously don't use an alkali (caustic) stripper on aluminium parts, but dichloromethane (methylene chloride) based ones are safe on all metals found in an engine. Wash off any residue with methylated spirits (or if you used an alkali stripper just with water). CAUTION: It will attack seals, gaskets and of course paint! Had not considered paint stripper, no Al. here, so worth a try. The only notable problem is that plastic toothbrushes don't last long in contact with dichloromethane based strippers, which is a pity as they are ideal for cleaning ring grooves, round valve seats etc. Tried the oven cleaner already, not so great. Sandblast would be interesting, but the shape of the pipe makes it impossible to really get inside with a normal nozzle. I'm actually desperate enough to be thinking of making a high velocity water jet with sand entrainment to try and scrape the gunk off "around the corner" of the chamber. Right now, I can get a reasonable cleanout only if I'm willing to spend hours fussing with it, and getting pretty grubby in the process. Must be a better way... bill Yeah, well, good luck. If you find something that works, let us know. I don't have to de-coke old British engine cylinder heads anymore, but it may be useful for something. d8-) -- Ed Huntress "Extrude-hone" comes to mind, forcing an abrasive paste/slury through the inaccessible passages. Perhaps that will spark some DIY ideas... I've seen a marine engineer (big ships!) burn out the carbon from a bronze exhaust system off a launch with a Stuart Turner two stroke engine - remove the exhaust from the boat, remove all the lagging, pour a cup full of petrol down it and shake well, build a bonfire round the whole exhaust and as soon as the flames coming out the far end died away, hook up a vacuum cleaner on blow! The result was an absolute inferno out of the manifold end and a dull red glow from the pipe. Apparently the trick is to rake the bonfire away from the exhaust once you have the glow and restrict the air supply as well if that doesn't control it as you DON'T want a BRIGHT red glow ;-) It actually took something like fifteen minutes to get the glow most of the way down the exhaust, at which point the engineer commented that it was now done, and he'd just let the bonfire burn out and it would be ready to reinstall the next day and it was also annealed as a side benefit! I've never had the need or desire to try it myself . . . . YMMV! Good thing it was a bronze part...I once tried gas welding a new header onto a steel expansion chamber, and managed to diffuse enough of the carbon inside the pipe 'into' the steel, that it just snapped off, so darned brittle! -bill |
