4 SCRATCH BRUSH SET : Brass Steel Nylon Fiberglass Watch Repair Rust Clean Tool (40)

I bought this set as an addition to my Coin cleaning kit. They comprise; Red is Fiberglass, Blue is Nylon, Yellow is Brass, Black is Steel. The fiberglass is for stubborn grot (dirt) on the coin, but is not strong enough to damage the coins surface. The Nylon I use with water to clean the coins. The brass and steel will be used on coins that are dirty but have no value, like modern day currency. They are high quality and cheap and function as they should, Happy.

They are used for cleaning some old coins I dug up when I used to go metal detecting

The media could not be loaded. Fab cleaning pens. Easy to hold which helps for detailed work especially on electronic components and connectors.

A handy set if only I can remember where I put them

Cleaning dirty contacts on pcb’s

I got these for something other than their design idea, I use them for cleaning the handmade coils in my vape, the nylon brushes work very well on cleaning the light caramelised eliquid from the coils while the Steel brushes easily tackle the more heavily baked on crud, I can imagine they would do an equally good job on circuit boards which is what they’re actually for.

These are nowhere near as good as the similar tools I used to use years ago, but they were quite inexpensive and got the job done.

Was looking at these for a while for some electronics restoration, my friend suggested them and I'm so glad he did, just make sure to wear gloves when using the fibreglass one
