WD40 or Silicone Oil?

Post by Mark

Oh yah, the grease works great whether it is silicone base or just simple gun grease and, as you note the detonator will stay cleaner as the grease seems to help combustion of the phosphorus or something like that. The grease helps combat friction and lessens the stress on the O-rings as they don't have to drag across the inner walls of the cartridge dry. Grease might help the 5mm O-rings on the Ingram and the Tanaka 5mm cartridges too and they might not tear as much as the dry ones do.

You really cannot beat the MGC series 70 .45's as you can see in my video, the MGC Combat Commander (HW) works great and it actually feels like a .22 when i fire it. The more that i fire these HW modelguns the more that i enjoy them over the ABS models. Collecting cartridges seems to be my hobby lately as i am seemingly just collecting them now and not as many modelguns as i used to collect. A person could if they wanted, could just collect modelgun cartridges and have several variants in their collections.

Are we talking about thick grease? Not just silicone oil?

Post by Claymore

Yeah rizzo its grease out of a tube so thick stuff not spray can, tried the spray and not very good for the piston.

I got my grease from maplin about £2.99 a tube i have not been able to find tubs of it unfortunaly.

It seems to work great and is not as dirty as using oil which is great as the gun will function a lot better.

The grease for airsoft cogs etc would be fine i think.

if i use wd 40 once on a stock jg md, what will happen to the barrel, hop-up and hi cap mag internals? please reply cause im a new airsofter and i kinda used wd 40 cause i thought it would clean well until i saw this forum. please reply

Hello maximoto, welcome to the forum

As far as cap-firing modelguns are concerned, WD40 is usually best avoided. Plastics and Rubber can deteriorate if it is used. Opinion is that the propellant and other chemicals mixed in WD40 do the damage eventually.
Purpose made Silicone Gun Oil is claimed to clean, lubricate and repel moisture from all types of guns, plastic, zinc alloy, steel etc.

For general cleaning of barrels, you only need a very small drop of Silicone Oil (the thicker type sold in Dropper bottles) applied to a patch and pushed through the barrel with the cleaning rod.
Make sure your hop-up rubber is backed right off or the rod may damage it.
Magazines will either be plastic or metal, either way the Hi Caps have a spring and tensioning mechanism inside. Too much oil can clog everything up, so only use Aerosol Silicone Oil very sparingly and not too often.

WD40 can be used on Detonator Pins and in Chambers to create extra smoke when firing PFC cap firing modelguns but this cannot be achieved with Airsoft type guns.

I hope this helps you some

I ask in this old thread just for the sake of it. I know from my own experiance that WD40 WILL destroy your model gun. However at the moment I dont have accsess to silicone spray.

However I have a can of Lithium grease spray. You guys think that could work or will it have the same effect as WD40?

Thanks!

How thick does the Lithium grease become once it's been sprayed onto a surface? I've used lithium grease straight from a tin or tube for "heavy duty" jobs but not on small intricate parts as found in modelguns.

Silicone grease works well when lubricating cartridge 0 rings. Silicone oil is great for lubricating plastics and 0 rings. 
Gun oil would be well suited to lubricate, clean and protect metal surfaces and parts but like all lubricants use it sparingly.

Thank you for this important thread.

I have posted this on another thread about a MGC HW model, but it sure does belong here:

Tomio from SHOEI in Japan told me what the extra instruction sheet is saying:

Please note

Use MGC Teflik for maintenance...
Teflon blended lubricating spray

Many of our products use plastics such as ABS and polycarbonate.
If you apply metal oil to these materials, it will not only melt or crack the surface, but it will also attack the inside deeply and may even cause it to fall apart.

Be sure to use MGC Teflic for maintenance. With TEFLIC, you can use it with confidence without such troubles.

Machine oil cannot be used.

Never use oil for metals, including motor oil, sewing machine oil, spray-type lubricants such as CRC (rust remover/lubricating spray sold in Japan), and rust/stain removers.

Please note that we may not be held responsible for repairs or replacements of malfunctions caused by the use of these oils.



Thank you, Tomio!

We had discussed before that some oils and lubricants may damage the already brittle HW plastic.

Alright! Thanks for clearing that up. Luckily I had a spare can of airsoft silicone spray I can use for now.
But now the question is where do I find some Teflic?

There is a range of Teflon based lubricants about but I can't find references to Teflic anywhere.

I wonder if forum member shazhib can get you some from Japan?

If it was a MGC brand it will most likely no longer be available. But i am quite sure that MGC didn't produce this Teflon spray themselves ...

Found this on Amazon : https://www.amazon.co.uk/GT85-Lubricating-Teflon-Spray-400/dp/B0185ILBRO/ref=sr_1_5?crid=23I4K9ZK9KXH0&keywords=teflon+spray&qid=1700839678&sprefix=teflo%2Caps%2C113&sr=8-5

Good find might work! I am just getting a little worried, all of the pictures show using the spray on metall objects where most modelguns are plastic ..

Hi

I heard a reason WD is bad for plastic is actually it contains bit of a Thinner kind ingredient which destroy plastic in a period of time.

My suggestion is, do not apply oil, grease, silicon or whatever to plastic or zinc parts. Maybe little of silicon to clean a surface, but not much. Use machine oil (not spray, but old school bottle type) onto a steel parts (mags, ejectors, extractors). But again, never apply excessively, just wipe a surface to have a thin layer.

Sorry just to make sure I understand correctly.
So what you are saying is mostly use just water while cleaning? And use small use of silicone for surface and for steel parts use machine oil?

Yes, that is how I maintain my collection.
After I fired with the caps, I usually just soak the parts and rounds into warm water (running water for a barrel), that is good enough to get rid of any residual chemicals from firing.
And just apply machine oil a bit on to the steel made parts.

Those chemicals used for the real firearms seems too strong to maintain a condition.

Alright! Great thank you so much for clearing that up for me!
