Bought to clean my files should do the trick

Good brush with a nice handle that feels secure in the hand. The bristles are a good hardness for cleaning my 3d printer. Only thing is that the bristles aren't especially well secured and several pieces fell off the first time I used it. I'm hoping there were just some stray bristle pieces from manufacturing, but those could contaminate what you're cleaning, or end up in your finger if you're not careful and don't notice them falling off. But I guess we'll see how long it lasts without losing more. Either way, I suggest brushing something to knock off the excess bristles before using it on something more sensitive.

Cleaning

i would prefer a smaller brush with the bristles much closer together... wouldnt need to be nearly this big.

Excellent for cleaning hydronic furnace heat exchanger.

great little brush, using it to clean pruning saw

While the brush is well made, it is not copper like description states. Brass and gold are gold in color not copper. I will assume it is not actually gold.
