Cleaning a carburetor in an ultrasonic cleaner what household solution to use
Permalink  
 

I'm going to be using my first ultrasonic cleaner soon but I need some help on common cleaning solutions to use found around the house, its a 30L so it takes a lot of solution especially if I buy it pre mixed instead of a concentrated solution, I've been reading up what to use and the MSDS (manufacturer safety data sheets) of all the soaps I got in the kitchen and a bottle of car wash I have but they contain chemicals that are not good with carburetors, I don't have a pH meter so I'm not sure about how much dish soap I could use if it has an alkaline base or caustic base, I know not to use a Lye base (NaOH) or know as sodium hydroxide and there are many more not to use bases but some of the chemicals in America like Pine Sol or Dawn dish soap are not available here in Australia, in my kitchen I have Morning Fresh I guess it could be used I can do a test with a sheet of aluminum foil to see if it eats it away. I have also read to first use a can of degreaser on the caby and wait till it dries then use it in the ultrasonic cleaner with dish soap is this a good way to do it? One last chemical I read about that's safe on carbys is D-Limonene a natural solvent made from citrus fruits but it might not be safe with plastics.

Has anyone found the manufacturing safety data sheet for the Bowden's Own Orange Agent Cleaner: www.supercheapauto.com.au/p/bowdens-own-bowdens-own-orange-agent-cleaner-770ml/588683.html it says its pH neutral and is citrus based that doesnt leave a white residue on engine parts and is safe on alloys

It looks like you are on your own here in new TTR250 territory Shaun!  So please let us know how you get on!

All I can see is that I have tried a variety of different cleaning solutions in my ultrasonic cleaner and none of them did a decent job on the TTR carbs. Sorry to be negative cry

I used Morning Fresh dish soap in my first test and the carby I tested it with was a PZ30 its a Chinese copy for their china bikes but Morning Fresh didn't eat the aluminum so I tried it on the carby I had in the TTR250 it is a copy too of the original and it went well too so I tried it with the original TTR250 carby and it went good too, nothing of the 3 carbies were eaten or made black....but I tried it on a lawn mower carby and it went a bit black but I cant remember at the moment if I used Morning Fresh or what someone else said to try Spray n Wipe so if you use either Morning Fresh or Spray n Wipe use a test piece to see if it gets blackened.

I have a 30 liter ultrasonic cleaner and because of the amount of water and cleaning solution I think dish soap is cheapest, one day I will try store bought concentrated solution but for now the UC is doing a nice job of removing grease and possible blocked airways but it wont come up like a brand new looking carby.

I read dish soap only needs to be a squirt or two not a whole bottle, they say less is more it has something to do with the waves of ultrasonic making its way through the water,

I also found out before using it not to mix metals in the one tank so when you do pilot and main jets and anything copper you can put them in a glass jar with the same water and cleaning solution in the jar and put it in the UC tank with the carby body but don't let the water/solution from the tank flow over into the glass jar, also as I remember never put gaskets in the UC or it will destroy them I'm talking about the paper and fiber ones but I think rubber is safe but it depends on the cleaning solution.

Some of the parts I put in had rubber and plastic while using the dish soap and they were fine no damage happened, also heat is used with the UC its a big part of it working correctly if you have a 30 liter tank put hot water in from the tap or you will be waiting a couple of hours for the unit to heat it up and only heat the solution to 60 degrees because when the ultrasonic waves are turned on it will go up about 5 degrees.

I washed my carbys for 30 minutes each its the most the inbuilt timer goes to and then it shuts off.

I tried an aluminum engine cover with lots of gunk and it was a bit meh to see the final result with dish soap, it cleaned it but it didn't look any better

I'm hoping a concentrated solution made for aluminum will make it look better.
