I have so many cleaning fluids and every one is meant to be the best on the market!!!!! well I decided to do a simple test.
I put a bullet into different pot for each of the cleaning fluids, Then added the fluids as labelled. In the 1st pic the fluid was left for 5mins...
The 2nd pic is 11/2hrs later. The big pot is Forest Bore Foam after 20mins.... I forgot to do that one from the start.
As you can see the wipe out & accelerator starts removing copper almost instantly.
The Forest Bore Foam is almost as quick.
The rest shows no signs of removing copper.
the eco gun oil is a dark green fluid and there was no change in colour.
I repeat this is a simple test and therefore not scientific.
