Right stuff for TB clean?

[CupraUK]

I'm going to clean my TB tomorrow. I could not get hold of isoproplyl alcohol but I got Wynn's Electrical Contact Cleaner, which is an alcohol based spray.

It says on the can:

Cleans and degreases
Leaves no residue
Quick drying
Safe for ECUs

This should be OK shouldn't it?

Should have thought it would be ok, I have some that I use for cleaning electrical bits.

You can't actually buy neat isopropyl anymore, it's a listed substance (can be used to extract THC from weed).

Oh realllllyyyyy. I wondered why the pharmasist looked out of the little room to see who was asking!

How often does the tb need cleaning?

Carb Cleaner is the same stuff (as TB cleaner), Halfords/Motorworld both stock it.

Remember when using this that some of it is going to go into/through the engine so is it worth risking alternative products ???

It should be able to remove grease & general dirt but also be able of dissolving tar/gum that can build up in the pipes - the stuff i have does not say what it has in it though, but it aint just IPA.

BigLad - i do mine before every track night (a quick/light clean, no strip-down), and get stuck right into it twice a year, after doing it i can feel the difference

Ive done mines around 7k ago, i also used the carb cleaner, but i removed the tb, sprayed alotand let the dirt drip of into a sink, follwed by a pecie of paper around the flap edges to remove any trapped dirt!
How often should this be done?

 

[DodgyDave]

I do just about the same, but without removing the TB (just stick some cloth under it while in situ) - twice a year i do that.

Also remember to reset (or recalabrate) the TB when you are done

Theres a sensor just after it, which i herd dosnt like having any spray on it, so thats why i do it! may give a quick shot again soon when the car gets it service done

I don't get a choice! My battery doesn't last the week (alarm drain) so I have to disconnect on a Sunday and reconnect it the next Saturday as I don't use the car through the week.

Not in this british weather! you might as well get one of those wind fans on top of your roof!

 

[CupraUK]

both good ideas. I'll have a look for a solar one when I get paid.

Back on topic. I cleaned the TB up today. Nice and clean and shiny inside now. Not quite sure what the benefit is though, I can't belive the dirt is that restrictive.

Could not do a TBA as I don't have Vagcom, but I'll see if I can ask a favour next time I'm in a crowd of SCNers.

Ive got a solar panel lying around i interested.

by cleaning the tb, it helps it to idle better and stop the flap from sticking when it geta lot of dirt. Its not something you clean, only every time a oil change service.

Just read something online that makes some sense. There's a 1-2mm gap in the tb blades at idle (I hoped that was normal after holding mine up and being able to see through it!).

I guess any amount of crap in that gap is going to restrict the tiny flow of air at idle, then the ECU is going to have to compensate.
