Preamer 6pcs Brass Tube Pipe Cleaners Brush Set , Multi-Functional Bottle Brushes Long Brass Cleaning Wire Brushes for Cleaning Rust Set for Drill/Hand Descaling Rust Removal , 0.3"-1"

The purpose in which I bought the this product is to have a strong brush in which to clean glass beakers from Grime that forms over prolonged usage and it works splendidly while still maintaining flexibility.

Restoring an old machine, rusted seized pulley. I cut the hoop end off this brush and ran it in my drill. This was a tight fit and I ran it hard. It didn't fall apart. The twisted wire shaft didnt unwind. No wires fell out as many other brands I see complaints. If you run it in a drill like this, just be sure to run in the direction that would tighten the twist instead of direction that would unwind the twisted wire handle. These are tough, not flimsy and i'm leaving this review as i'm here to buy more. Good product in a sea of crap lately.

I live in an area of SW FLORIDA where 100% of the City Water has a high count of Limestone mineral in the water (our city well draw from a wonderful supply of limestone aquifers). Down side kidney stones and Lyme calcification build up on toilets. The water jets that provide the swirl of water for flushing get blocked and labored flushing is common. Lyme reduction liquids help but not enough. I looked high and low for the proper plumbers tool to scrub out this build up. No such luck. Literally I was considering replacing one of our toilets and this thought from (let’s say heaven) inspired me to make a Amazon search for small brass wire cleaning tools Sure enough, what I needed was plentiful. Wire Carburetor Cleaning brushes in all the right diameters. These items work wonderfully for just that purpose. Only wear some thick long gloves and dip the cleaning bristles in (for example CLR solution). You also need a pair of safety glasses. The process sure beats the cost of a plumber making a house call.

I have thing that is tube shaped which gets a pretty heavy carbon and lead buildup and requires regular cleaning. Due to the cerakote on the outside of the tube I can run it through the ultrasonic with chemicals like I do the stainless baffles, so instead I run it with just hot water to help loosen the buildup then use the largest brush and CLP to get in there and get it properly clean. The largest brush is perfectly sized for it. I also use the 2 smaller ones to get in the spots on the baffles where the toothbrush style brass brush can't get. I haven't had these long enough to say how they will hold up over time but the 2 times I've used them so far they've held up fine with the bristles staying in position as opposed to some others I've used where they bend in all different directions after first use.

Made well. They clean well, just an excellent product. I would recommend Preamer Brass Wire Bottle Brushes

They did ok but the center wires were too stiff and thick. On the smaller diameter brushes, the brass barely stuck out past the center wire.

If your are cleaning guns or suppressors, these are great brushes. The different sizes make carbon buildup easier to remove. They have lasts better than my brushes.

Brass is the perfect soft metal for removing hard water mineral stains from toilet bowl holes. I pour vinegar in the bowl and then use these brushes for cleaning the water jet holes. Perfect. Does not scratch the porcelain. Thank you.
