Konex 45 Inch (115cm) Premium Flexible Medium-Stiff Natural Bristle Radiator, Coil and Vent Brush with Wood Handle

I use this to clean the tubing to my turtle tank filters. Its nice and sturdy to reach all the way to the middle and it is easy to remove. Scrapes the sides of the tubing and removes the funk with ease.

It is long enough to reach, bend to fit what’s needed & slender enough to fit into tight spaces with stiff bristles. Used it to reach & clean dust laden heat exchanger under my frig. If you need soft bristles, keep looking.

I bought this to use to clean a tall, 36", bottle with long narrow neck. It was flexible enough to bend the end but still sturdy enough to scrub the inside without bending from the pressure. Worked very well.

Came coiled up in a bag. Hard to straighten out. Seems to work well.

1st use and all the bristles fell out. Until then it was great.

Super stiff which makes it hard to bend and use.

This is such a great tool. I’m finally able to clean out under the washer, dryer and refrigerator. There were dog treats, m&Ms, and enough lint and dog hair under the appliances to create a fully functional golem capable of defending my home from zombies. Seriously, this thing is great. It’s sturdy enough to retain its shape when getting cobwebs, and flexible enough to fit under appliances it into the small spaces on either side. I’m glad I got this and will be using it frequently.

I got this so I can clean in between my washer and dryer. Works great.
