Just got one for £20. Done my watch and some of the Mrs jewellery. Seems to work very well.

Injectors are next!

Any recommendations on the best solvent to use for this?

All the ones I've ever seen for cleaning household stuff have been nowhere near powerful enough for proper cleaning - it'll be interesting to see what this one works like. The one we used at work was a couple of watts output, worked well. The household one I bought apparently had 0.25W output, which explained why it would clean a ring just but didn't touch a spark plug.

There's an article in one of the motorbike magazines (practical motorbikes?) about using small ultrasonic cleaners.
They clean a carb. but it takes a couple of cycles and they use carb. cleaner.

Any good for injectors?

Did anyone buy one of these

Only me I guess

Was it any good before I buy one
