💎 Innovative Products 8040 Diamond Grip Terminal Cleaner Set - 3 Piece Review

They're great for cleaning ports, simple tools for a simple task. There's really no other way to clear the terminal. I will definitely buy a similar product to clean the barrel connectors.

I have used this tool several times to clean corrosion from a supposedly bad sensor and relay contacts. Works great for this purpose, pays for itself after the first suspect sensor saved by cleaning. It is highly recommended to clean the nibs with a non-aggressive detergent to prevent clogging (just like sandpaper with paint, the nibs can clog from the dirt it scrapes off the pins).

This is an excellent product for removing oxidation from electrical plug-in terminals. The small size fit into my washing machine's stranded motor port and brought it back to life. The ends only twist from the side to insert into the socket when needed to remove oxidation. All 3 sizes are usable. Usually use for pin terminals, just push and pull to remove oxidation. It is a necessary tool for repair work.

I've been looking for a tool like this for a long time. I work a lot with cars. If you've ever had to deal with rusted blade or bullet connectors, this tool will make cleaning a lot easier. Nice little purse to keep organized in my power tool box. The surfaces are coated with high-quality diamond dust and offer perfect abrasiveness. I also assume that the surfaces will last a long time. This item replaced an old steel nail file, sanding board and 220 grit sandpaper in my kit.
