Never use Motor oil on a BB gun. It will eventually ruin the seals and O-Rings.
If its a BB Gun, Then Yes.
Put a drop of Pellgun oil in the barrel. Also put a few drops in your BB container and work them around, Do not over oil and only use Crosman Pellgun oil, never use regular oil.
I have no idea what DG window cleaner is. But simple Windex window cleaner should be no problem, with cleaning the outside of the BB gun. Actually there are BB gun cleaning kits made by Crosman, RWs and Gamo. But you will have to find them online. A few things you should not use, are any type of regular firearm cleaning agents. They are too strong and will ruin the seals on a BB gun. I never use regular oil's either. I only use Crosman pellgun oil or RWS oil. Several sporting good stores carry them
You don't magnetize the BB's. The Magnet is inside the BB gun. The gun has to be taken apart and the magnet that holds the BB's replaced. Not all designs use this method of holding BB in place.
A BB gun is a gun which shoots BB-size pellets, typically with the use of compressed air, or a compressed spring.
I suggest Crosman Pellgun oil or RWS pellet gun oil.
In order to be used the Caliber must be .175 or it will jam or damage the gun. BB stands for "Ball Bearing". Never use a BB in a Pellet only gun.
It may cause problems with jamming. It is not recommended.
I use a Daisy Red Ryder BB Gun.
In mst cases, no, it is not- but it will depend on where your garden is located, and what you are doing with the BB gun.
The drozd is rated at 541 FPS. there is not much that you can do to improve it because it's a BB gun and the Co2 will only push the BB so fast. With a pellet gun you can select a lighter pellet to make it faster or a heaver pellet to make it hit harder. BB's all weigh about the same so you don't have much choice. However you can put your BB's in a can and drop a few drops of Crosman pellgun oil in with them and roll them around in the oil to coat the BB's with oil. Also put a few drops of oil down the barrel this will make the BB's fire faster down the barrel. DO NOT SOAK the BB's it will gum up the gun with too much oil
These rifles don't require much maintenance, Wipe it down with a mildly oiled cleaning cloth. Use Crosman pellgun oil or RWS air gun oil to oil the joints and moving parts. Don't over oil it. Put a drop or two of oil down the barrel every 500 bb's
