I have a pair of 1 1/2" SUs which I am dismantling to rebuild as spares. The shafts have almost no play so it is a matter of cleaning and putting a new kit in them.

What is best to clean them? Something I can leave them in overnight or for a few days would be preferable if available.

Hello John,

I once used the dishwasher to clean a pair SU’s. I did it while my wife was out at the hairdressers. (I knew I had several hours to myself.)
When she came back she was none the wiser. She did, however, notice the cleaned up carbs in the garage.

“They look nice and clean” she said.
“Errr… Yes, “ I replied, “I  cleaned them with Gunk and a toothbrush.”

She then said “You should have put them in the dishwasher. It would have been a lot quicker.”


It does work well, especially if you have them all in pieces. (Put the smaller pieces in a wire basket.) And DON’T use a dishwasher tablet. I believe that they can attack the aluminium.

Saying that I must have used some sort of detergent, but not sure what.
I would not recommend using Gunk though. You might have Gunk smelling plates for weeks to come.

Charlie.

If you know anyone with an ultrasonic bath that works a treat, paraffin and a stiff toothbrush is the poor mans way of cleaning up.

I'm with Stuart on the use of ultrasonic cleaner baths  here are some additives:-

Failing that I have great results with the aerosol stuff

PS  Wear safety goggles when using.  I ended up in hospital after splashing the stuff in my eyes.  An hour of having my eyes washed out with some neutralising solution.

Dose the STP aerosol spray clean up all ali parts Pete ???

Roy

In my experience, It certainly does a good cleaning job of fuel and oil staining.

Be careful not to spray it on paintwork as I suspect there could be tears

Cellulose thinners works really well and gets rid of the brown staining from the petrol residues - if you use gunwash thinners, its not expensive

Thank you all. I'm going to buy an ultrasonic cleaner, I expect with two TR2s and a TR6 (plus another car if I can find the right Mk1Sprite) there will be more of this type of cleaning in the future.

Its quite surprising just how much dirt comes off of carbs, here’s my 20l after four or five sets of ( very dirty) old motorcycle carbs !

Dishwashers are fine. Thinners is good too.

Did a sump in the disshwasher prior to painting it but not sure I got away with it. Did a Boris & bluffed it out!  Should have done a second cycle with it empty afterwards!

I used detergent concentrate in warm water. The cleaner had an 8 minute timer limit but after five or so cycles the carbies were clean, not shiny.

As they had been in a shed for over 50 years and covered in layers of grime I'm pretty happy with it.

I'll buy one of the carbie concentrates and do them again.

I now need new shafts and a carbie kit.

Unfortunately, these businesses don't deliver to Australia, and I can't find a distributor down here.
