Wingman Posted February 10, 2017 Report Share Posted February 10, 2017 As the topic says really whats the best way to clean the choke threads inside the barrel? I thought about a bronze brush but read somewhere that this is bad as the bristles sometimes get stuck in the threads. After years of shooting I realised I dont know what the best approach is. I only usually remove the chokes every now again but one of mine seems a little "gritty" when tightening. Thanks all Quote Link to comment Share on other sites More sharing options...
TIGHTCHOKE Posted February 10, 2017 Report Share Posted February 10, 2017 An old toothbrush is perfect. Quote Link to comment Share on other sites More sharing options...
wymberley Posted February 10, 2017 Report Share Posted February 10, 2017 A new one is better as is a nylon bore brush. Quote Link to comment Share on other sites More sharing options...
TIGHTCHOKE Posted February 10, 2017 Report Share Posted February 10, 2017 Why would a new one be better, after the first use it will be covered in oil and carbon. New one for my teeth, old one for the gun! Quote Link to comment Share on other sites More sharing options...

New one for my teeth, old one for the gun! Probably because just as a new PB brush cleans better than an old worn one. But there again, i use Steradent.

Exudate Posted February 10, 2017 Report Share Posted February 10, 2017 I spray a new toothbrush (you can get them for less than £1 each in supermarkets) with Napier gun cleaner and give them a good scrubbing, followed by a wipe with kitchen-roll. Only needs to to be done about once a year, if that (I find). I then put a generous smear of gun-grease on the choke threads before putting them back in.

steve_b_wales Posted February 10, 2017 Report Share Posted February 10, 2017 After cleaning the threads with a soft bronze brush, I smear a small amount of Copper Slip grease on the barrel/choke thread. Quote Link to comment Share on other sites More sharing options...

Wingman Posted February 10, 2017 Author Report Share Posted February 10, 2017 Just tried a toothbrush with a few drops of youngs 303. Bit of crud came out but the choke is still a little gritty but only when its nearly at the end of its travel (ie, nearly fully tightened and in). Wont worry about it for now, it seems ok and now their in they can stay there for a while! Quote Link to comment Share on other sites More sharing options...

Okay, remove the choke, stand barrel choke downwards in a jam jar, pour in oil to above the height of the choke pockets, leave to soak. It would appear that it may be the inner part of the pocket that has something gritty in it rather than the threads.

Old farrier Posted February 10, 2017 Report Share Posted February 10, 2017 One normally gets a thread cleaner on the other end of the choke key It's in the gun case next to the spare chokes chamber brush and cleaning kit Appreciate some old school makers find multiple choke options a bit modern however we're in the 20th century so personally Would suggest a strongly worded letter to your gun maker if it's not there Allegedly some of the continental makers also do them All the best Of Quote Link to comment Share on other sites More sharing options...
subsonicnat Posted February 10, 2017 Report Share Posted February 10, 2017 (edited) A lot of the crud is in the choke key slots,So cleaning BEFORE removing the chokes is of benefit. That way you not turning the grit when removing them. External chokes probably do not have so much of a problem.

Hamster Posted February 10, 2017 Report Share Posted February 10, 2017 Oily rag twisted around an old toothbrush just tight enough to feel a bit of resistance as you twist it in a few inches and repeat with the clean part of oily rag.

figgy Posted February 10, 2017 Report Share Posted February 10, 2017 Carbon solvent on old toothbrush and leave to soak scrub again, clean out the gunk with a cloth and then grease up the threads. Quote Link to comment Share on other sites More sharing options...
Wingman Posted February 10, 2017 Author Report Share Posted February 10, 2017 Thanks All will try these options, no thread cleaner on the key by the way, its a Perazzi with knurled extended chokes I am using my teague taper key to tighten them as i dont have the original. It seems that its mainly one oft the chokes I have tried the others and they seem easier to tighten, I have dropped it into a jar of acetone to see if it cleans out the threads.

Best option here saw the end off and do without 😂 Seriously though it could have a little damage to the thread Check another tube in the gun and if no problem check the thread they build to a very tight tolerance All the best Of Quote Link to comment Share on other sites More sharing options...

bakerboy Posted February 10, 2017 Report Share Posted February 10, 2017 I periodically soak my chokes in paraffin overnight. I use a toothbrush and dip that in a bit of paraffin to clean the thread in the barrel, ensuring the tread is wiped clean before applying the usual grease and oils that we all use.

One of your chokes may have been dropped and no longer be perfectly round, also don't forget that cleaning the thread on the choke is only half of the job!

figgy Posted February 10, 2017 Report Share Posted February 10, 2017 I don't clean my chokes until when I back them off they start to feel grainy like sand in the threads. Then time to remove de coke and regrease, I grease all of the choke that goes in the gun and a smear on the inside of the muzzles not just the thread. No chance of rust or binding.

I think I have been to sparing with the grease, normally only put a tiny amount on the threads... Quote Link to comment Share on other sites More sharing options...
johnnytheboy Posted February 10, 2017 Report Share Posted February 10, 2017 Brake cleaner aerosol blasts out all the grime, I used my bronze brush for this all the time with no issues the threads aren't deep enough for things to get trapped in them so it's all good!
