bought a t/c renegade, and cleaned it after shooting it by using the pre-moistened patches made by t/c and ran through 4 and they came out clean. I then put a dry patch down and then an oiled one.

is this ok or am I missing little nooks and crannies in there which may rust.

I know people who dunk them in hot soapy water, is that necessary and can I take out the breechblock to clean it

^^^This^^^

Only way to go! I've got the same rifle in .54 cal

After I do the hot soapy water, I then treat my barrel with T/C Bore Butter.

Your method is okay for a field cleaning. For a thorough cleaning, take the barrel off, remove the nipple and submerse the breech end in HOT soapy water. Put a wet patch on the jag and run it in and out of the barrel and it will pump the solution in and out through the nipple hole and wash out the flash channel in the breech plug in the process. Run some HOT clean water through the barrel, run a couple dry patches through the bore and let dry for a bit. Run an oily patch down the bore, wipe the outside down with an you favorite rust preventative and reassemble.
The breech plug is removable but not necessary or recommended. It's very tight and the reason you see barrels all scratched up. Seen more than a few with pipe wrench marks.

so what I did isn't enough

Good for a field cleaning, but doesn't get the breech plug face or flash channel.

this! I've had mine since 77, still looks new!!!!!!!

I do what tmitch does as well. Mine is still without any significant rust since the 80s. And I agree with him that you are fine for field cleaning or on a hunt, but you need to do the full cleaning before too long. I used to not use the oil after cleanin, but am now a believer that this is the best way to protect the bore.

Also, when you go to shoot the next time, you still have oil in the bore and you need to clean that out before you shoot. Windex on a patch works or alcohol. Run a couple of wet patches down followed by a couple of dry patches. Then pop off a few caps and swab the barrel with a dry patch, then load up.

Same here!
I use a plastic coffee can with warm water and dishwashing soap.
This method makes it an easy job for hooked breech guns.
Now my flinters with pinned barrels, I use a device that looks like a c-clamp with a hose and o-ring that fits over the touch hole.
I'd stay away from petroleum based oils in the barrel unless you clean all the oil out, as it will foul powder.

It's also not a bad idea to remove the lock while you clean. Lots of crud works its way behind the lock.

Did the hot water suction thing in the sink. Must have gotten it pretty clean as only a tiny bit of black charcoal came out the nipple.

Thanks for the help guys

You have to take out the nipple to do it. The nipple is too small a hole to do it right.

I use a plastic bucket. How can you do it in the sink? The barrel needs to be vertical when you're swabbing the water in and out.

I had the breech under the hot water in the sink and it sucked water and pushed it out just fine. Was about a 45 degree angle

If you didnt pull the nipple, give a good clean and rinse, you may end up with rust down the road. Leaving the nipple in may not give it a good flush, plus you are not flushing out the threads.

I use one bucket to clean, one with clean water to rinse. An easy way to get the water out is run a couple of patches thru, then pour rubbing alcohol down the barrel, dry patches and then oil the crap out of the barrel.

I have a 54 Renegade that I have owned since '89 and the bore is spotless. If you are not absolutely certain that you got all of the BP residue out, you didnt and thing will rust.

The nipple gets removed and cleaned separately like I do for my inline nipple and breechplug

Take it out. You'll get a better flow when swabbing the soapy water, and clear water.

when i hunted with a side lock i glued up a barrel length section of 4in plastic pipe so could fill it with really hot soapy water and let soak. i made a wooden stand to hold it vertical.

I clean them in the sink all the time. Put the plug in, fill it up halfway with hot water, shoot some dish soap down the bore, and have at it. If it's really dirty, I change the water a couple of times. After it's clean, I use alcohol in the bore, let it dry thoroughly, then oil it. No rust yet.

I find it easier in a plastic bucket holding it almost vertical. My sink is stainless, and the barrel would scratch it pretty good if I did it in the sink.

Get some Ballistol.

You can use it staight or diluted to clean the barrel and then swab the bore really good with it straight to prevent rust.

If you do the bucket thing, swab the bore good with a well-soaked straight Ballistol patch or bore swab. Even if you failed to get all the water out, Ballistol will mix witn the water and still protect the bore.

You can even put it on your boo-boos, although in the U.S. it's not approved for that.

Hot soapy water and Palmolive on a bore with 4 shots fired last night. Not sure why I even ran a 4th patch the 3rd was spotless.

I love Ballistol, that stuff really gets the bore clean. I used to think it was a hoax until I tried it. Dont know if I could use it straight tho, that stuff friggin stinks! But it sure works great on BP.

When I was shooting a flinter, I had had constant trouble with light, powdery rust in the bore, despite all the "conditioning" voodoo I was doing. Ballistol put an end to all that.
