My experience with bore cleaning

[Oldbloke]

Cyanide is great for leaching gold and copper.

Being a natural product Im sure it has plenty of safe uses.

[Oldbloke]

Just slightly off the topic.

If you just fire a couple of shots out of a rifle a month, how often do you clean?

[SCJ429]

I clean my rifle every time I take them out.

I found the MSDS sheet for Boretech Cu+. No Cyanide thank goodness.

Working in chemistry (research) area with MDSD's aplenty you would think i would look into what cleaning solvents contain what....

Cyanide (<5%) in KG12 - this made my immediately bin the stuff. Having used it sparingly in the past (without any gloves!!) - bugger me.

I think i may look to use disposable gloves from now on when cleaning rifles.

The level of cyanide in the KG12 could pose a problem with long term use - you would think the packing would alert you to use PPE of some sort.

Will stick to the Boretech gear from now on.

Every time I use them mate, for my centrefires anyway.

at the end of the season, around 6-8 months, maybe 20 shots unless l think it really needs it

Sooo... just thought i would regurgitate this thread. Normally for just cleaning carbon/soot out of my centre fires I just use eds red so I bought some of this carby cleaner from Supercheap Auto last week thought id give it a crack. Turns out the bores weren't as clean as I thought. Yesterday I spent 3 hours cleaning 2 and today I'm spent about another 2 hours cleaning out another. Plenty of carbon crap material is still coming out so give this stuff ago. Seems better than eds red can't speak much about other carbon cleaners.

Use sweets for copper once a year.

P.S. I clean my rifles almost every time i use them so am assuming they were cleaned after last use.

[SCJ429]

Carby cleaner is very effective on carbon. Good for cleaning throttle bodies too.

[Sergeant Hartman]

There is a foaming one... i find 2 patches is max it ever needs

[Stix]

Yep...interesting...

I bought same brand brake cleaner for same purpose.

I briefly tried to find out what the active ingredients are in carby & brake cleaner, but couldnt find anything.

Asking a few people in shops, it was suggested that brake cleaner would be better for baked on carbon, but the suggestion didnt come with any scientific backing....its just based on assuming brakes would get hotter than a carby.

I even asked a manufacturor & no one could tell me the active ingredients so i dont know which one is better for baked on carbon.

This SCA brake cleaner is no good for painted surfaces & rubber parts...so obviously cant do timber stocks any good...so being paranoid i walk out the room to spray the patch...lol

Is the carby cleaner also bad for paint & rubber OldBloke...?

Stix, both toluene and acetone disolve various plastics. So be carefull with plastic stocks and magazine followers. I suspect same with paint and rubbers. I think acetone is ok with timber.

Regarding safety. Acetone us at the low end of toxicity scale. Pls understand not all carcinogenics are equal. . Everytime you fill up with petrol you are breathing at least some benzene.

We use very small quantities. Just ensure pleny of ventilation. Eg open a couple of windows or doors when in use.

Cant speak about the other substances.

EDIT My mistake. benzene and toluene are carcinogens. Have edited the above.

[Sergeant Hartman]

Most petrochemicals are toxic or carcinogenic.

If you want ingredients, look at the MSDS of these things not the label on the bottle/can. Only food has standards that require all ingredients to be listed on the label, other things like this might or might not have all ingredients listed on the label.

Have have a look at the MSDS from nulon, for a similar product. Click on msds button.

Whats your point mate.

[Am88]

I was at one of the ranges here on the weekend playing around, and a bloke beside me set up his monster, I have no idea on classes for target shooting but this thing looked one of those rail guns but he had it on a rear bag and front adjustable stand thingo, I felt inadequate with my measley 1 1/4" barrel when he had this thing that looked like half a length of 2" solid bar threaded to an action!

Anyways first thing he did was clean it, with turps, a bronze brush and patches. Could smell it was turps a mile away, I'm quite certain there would come a time he uses copper remover as i did see a bottle of sweets in his range box.

[Stix]

Maybe he's using that to float out the carbon AM88...
Maybe White spirits or Shellite...?
They are used a fair bit for a final clean to remove all solvent as they apparently dont leave a residue.

Anyway, interestingly, there are NO active ingredients listed on the same branded can of brake cleaner--aside ftom stating its a hydrocarbon propellant.

That might mean its cancer in a can...

Would be interesting to see which removes baked on carbon more effectively.

[Sergeant Hartman]

Stix i have a can of nulon air intake cleaner foaming but they don't make that anymore. Try nulon upper engine cleaner.

Usually run 2 patches and 3rd one is clean. Even boretech copper eliminator cleans the carbon reasonably well

[Stix]

Thanks Ziad, but im not buying more stuff...its not as though i have nothing to clean the carbon with.

Just thought it might be an interesting experiment

[Sergeant Hartman]

Just buy it anyway, and send it to me... hehe

[Am88]

Possibly Stix, I didn't sticky beak too much into his box, I was too busy being embarressed by my severe lack of barrel thickness

[Oldbloke]

Here is the SCA brake cleaner.

Every few years I go to a local commercial printing place and grab 4 or 5 L of 100% Isopropyl ( they pour out from 20L drums, paid $8L last time from memory).

doesnt damage ya car paint or plastic, I was using it to remove sticker gum as I was competing on a montly basis over the last few years.

Its what they use to clean large scale presses and also a lense cleaner. Fantastic on carbon too.

Helmars 7500 is by far the best non toxic dedicated carbon remover Ive used and it even removes copper just not as quick as Boretech. Locally made and cheap too.

Bill - I’ve read some great comments from you, I’ve read some average and outright disagreeable comments - but PLEASE explain who the fug competes in sticker gum removal?
Is it like a race to get the stickers off or what??

[sungazer]

I think he means that when he competes they place a sticker on his gun to show that it has been inspected, weighed ect and passes. Isopropyl is ok on some adhesives but if you really want a top shelf remover try Xylene

[Bill]

TassieTiger Ive been racing Honda civics for the last 8 years, window banners, numbers on doors, event sponsor sticker all leave some sort of gum and Isopropyl is great for cleaning things.

I also mix it with dry ice to create a liquid slurry that freezes and allows soundening to be removed from under the carpet in a car and the boot area, I removed close to 15kg of weight out of a civic

[Bill]

its a fantastic cleaning product, just expensive when you buy from a pharmacy

It was jest...mere jest. I’ve got the same decals placed on my race bikes at circuits and strip.

On another note - watched a civic and late model fort gt mustang at Baskerville last year...was the most entertaining thing I’ve watched for a while. Civic got him but then got a penalty - it didn’t lose a metre on back straight to the v8...penalty was for going round outside of Stang onto grass in last lap. Great stuff.

[pomemax]

DD Eucalyptus works just as good on sticker adheasive the base of the adhesive is Krayton rubber mixed with some small amount of natural rubber and Toluene few different chemical added for shef life and stuff like that .
When i was working at the factory that makes the adhesive they had a BULK DD to remove it from people if they got covered in adheasive and it works on steel too.

[flutch]

@bill

Civics aye? What's the view like from the back of the grid?
