ultrasonic cleaner

[Random13]

Hi Guys,

What is ultrasonic cleaner and what solvent should you use in it ?

I am considering buying one to clean my injectors but not sure if the same result can be achieved by simply leaving my injectors in the injector cleaning solution for 1 hour or so.

many thanks

[Random13]

and also my calipers

Not sure if it will do a good job of the injectors. you can get different cleaning agents, depending on the material/metal type.

I tried using a cheap one and didn't have much success.....but I've seen other people on line have better results I've heard people using vinegar .....and coke, but I'd stick with the proper stuff.

Not done injectors but for carbs I use a carb cleaning solution supplied fro Ultrasonic cleaners Ebay is you friend

I also sometime Use Penetration fluid but with great care as the fluid tent to heat up and over do it and you have a fire

Don't use highly inflammable cleaners like conventional carb brake cleaners they could easily catch fire

Don't use unattended

Mine is a6 litre commercial unit makes a great tool for carbs and brake callipers!

For ultrasonic degreasing use trichloroethylene

Injectors can't be cleaned at home, they need a professional setup to do it as they must be correctly activated and lubricated for them to be cleaned internally. There are a few places that offer the service around, so I'd just Google them and see what you come up with.

There is no need to be stripping and cleaning injectors.

What is the recommended service for M/C injectors. I've never had an Fi bike before so havn't a clue. I've had injectors from boats and cars serviced...there's a great little garage that specialises in them in one of the local villages...at least it was there last time I used it, you never know nowadays

Had an 18 year old car with injectors that had never been touched and it ran perfectly well.

Injectors, on any vehicle, won't usually need cleaning unless the vehicle has been sat unused for years. Fuel can turn into a varnish-like coating inside the injector over time but an engine that is run reasonably frequently will seldom need attention to the injectors.

well I have always felt a difference when I have cleaned my injectors.

I don't open and close them etc .
I just soak them in petrol or wd 40 for 1/2 hours.

and then give it a quick brush .

That is all.

Regarding the ultrasonic, I shall buy one

https://www.maplin.co.uk/p/jpl-ultra-7000-ultrasonic-cleaner-075-litre-a46hq

the one above, is it any good for my application ? it is less than a liter, can I fit caliper in it ?

it is not anything dangerous or hazardous , is it ?

can I just use water and if not sufficient then use vinegar ?

[Vincent]

That's pretty small.....I'd go bigger, and/or look for a used industrial one. Or do one side, then the other

yes rather get new and small . can keep rotating it .

One question, I won't be shocked or my skin won't come off if I stick a finger in, would it ?

considering it is 2-3 mins for each cycle then a caliper could take 10 mins to clean depending on how big it is .

what solvent would you use apart from water?

[Vincent]

As far as I'm aware, the cleaner is safe - you probably won't want to drink it but it won't burn you or anything. It took a hell of a lot longer than 10 mins to do a carb in the one I had and when done, I had to brush off all the crud it had loosened. I'd degrease with gunk or similar and a brush first.

Injectors do in fact need maintenance if they are to work as intended. Problems include failing to open, failing to close (leaking), poor spray pattern and unbalanced flow across the set and none of this is good for your fuelling. A machine such as made by ASNU is used to check the flow and spray pattern, then run a cleaning process followed by another flow & pattern test to compare with the first. The people I have known to have it done have all reported improved idle and low running.

It's not an expensive thing to get done, probably £50-100 a set. If you're feeling too thrifty then you could rig up a PP9 battery to hold the injector open (don't use 12v or you'll cook the injector coil)and flush it through with copious amounts of injector cleaner or toluene etc, but you'll only have your arse-seat dyno to judge how successful you were. My mate rigged up a battery and pump to cycle cleaning fluid through his injectors in turn whilst they were in the ultrasonic bath, but he had to fiddle about to stop any parts touching the tank.

I have an ultrasonic cleaner, rather like one of these.

I've used it most successfully on carbs, particularly some 25 year old Bing carbs off an old airhead. Anyway, clean the thick gunk off first with a proper degreaser and then use the cleaner to get off what's left. I use water and a splash of floor cleaner to act as a surfactant. Maybe 10 to 20 minutes, then change the water and repeat.

Here's some useful info.....

I have had good luck using them to clean Carbs, Diesel injectors, nuts, bolts etc.

I do 2 or three runs for carbs, and thats with washing up liquid and kitchen cleaner in hot water.

[Random13]

I bought one of below

It doesn't do much . you can clean gold and jewellery with it but that it about it .

It couldn't clean the caliper or caliper pistons. It did however take some of the rust off (minimal ).
I used vinegar on its own. paraffin. water ,wd40 run it almost 30 minutes no results.

I have seen it in forums people swearing by them but didn't certainly work for me.
I don't think there is a significant difference between mine and something which costs £100 which is a more of home professional cleaner so no point going up

had anyone been able to take rusts like below off with them ?

I have seen some videos on rust electrocis which seems to do magic , has anyone tried below ? I don't want to waste money on getting the materials if it doesn't work

They don't remove rust do they? Just grime and dirt as far as I'm aware. You need a shotblaster for rust.
You deffo need the right cleaning fluid, esp for alloy - probably not much use sticking household detergents in there.
