Concentrated Cleaner Solution 1L General Purpose Cleaning Fluid Degreaser Dirt Remover 5% Concentrate

To be honest, I assume this does the job as it is quite obviously a detergent of some sort and it’s designed to work with ultrasonic cleaners.So far, I have only used it to clean spectacles, but it did that and dried off without leaving grease, smearing etc behind.I suppose I could have used washing up liquid but I couldn’t tell if it might foam too much.This is good enough for me.

I used this to clean a small gearbox which had heavy grease in it. I heated it up, and it worked well diluted about 1:10.

Excellent product and very good value for money

Beats soapy water hands down

It does not remove carbon so it's not for me but I will use for other applications.

Not that good on really dirty fired rifle casesBut acceptable after an hour in the ultra sonic bath
