Are they dirty jackets or normal jackets ??

[OliveOil]

Dears,


Have been cleaning 300 J4 .30 jackets today.

I use some kind of "RCA clean" that concists in 3 successive bathes of acetone, 20 minutes exposure per bath with 3 shakings during each of the 20 minutes long bath.

I am very much surprised to see such an amount of dirt in bathes 1 and 2, knowing that any lubricant remaining on/in the jackets have been dissolved by the acetone. So that's some kind of a solid remaining here.

Does this appear usual to you or do I have some kind of a dirty batch ?

Thank you.
Olive.

Buy Hines Precision Jackets from Bart Sauter. They are clean when you get them....In a bag with desiccant.

Thanks.
If I remember well, he does not export jackets. I am in France.

Years ago, I had one lot like those. But I neither trust or expect they'll be perfectly clean. I clean them and know they are.

A rinse in campfire stove fuel or alcohol stove fuel, followed by a acetone rinse, does a nice job.

Good shootin' -Al

Tumbling in a tumbler isn't a good way to clean jackets?
