You could try some Archoil Ar6400d as a cheap start point to see if that improves running

Doesn't it depend on how old , what mileage and what the op thinks is wrong with the injectors . If he just thinks it's a bit "rough" then isn't the cost of removal ,sending away for cleaning ,refitting a little excessive to start with ?

a spill test will give a better idea of whats wrong wighty , if they are spilling off a lot then a refurb is the only cure , if they are not spilling off then cleaning fluid cant not but help but again it doesn't do as thorough a job as the refurb will do

a lot of the time , the tiny spring in the spill return is either weak or broken and that release the pressure on the nozzle so you get less spray and obvs poorer performance from your car as combustion isn't as clean

I suggested this in another thread a little while ago, someone on here ripped me a new ar***ole, saying that injector cleaner is "snake oil" and is a waste of time :rolleyes:

Whoever that was probably meant to impart that small amounts of organic chemicals added to your tank, won't fix broken or worn injectors.

buy some stanadyne from dieselpartsdirect.co.uk , add to fuel as directed and go for an italian tune up, do that a few times will clean all the fuel line plus injectors
