Carlisle Foodservice 4000102 Sparta Spectrum Bottle Brush 16'' (1 Each)

Actually use this to clean under the hood of my cars and truck. Does a great job cleaning the engine bay and seems to hold up to the abuse. Bristles are much softer than your everyday toilet brush.

This  Carlisle Brush Bottle Large 16" (13-0841) Category: Scrubbers  is the best size brush to fit down inside an old-fashioned, standard-size, one quart Thermos or Stanley vacuum bottle. The handle is long enough that you can use it to scrub the bottom. Pour in some salt first, if you need a little more abrasion. I do hate that I had to spend $20 on it with the shipping, which is the only reason I don't give it five stars. No Super Saver shipping, but it's a good brush. It did keep me from having to buy a new Thermos, hahaha. Now I have the brush for the next time my Thermos gets cruddy with tea stains and needs a good scrubbing.

Still the best!! Hard to beat.....Joe

I purchased this brush because it was long enough to clean milk bottles. Unfortunately, the brisles are too wide/stiff to fit into the inch and a half mouth opening. What good is a brush that can only be used to clean bottles that I can also fit my hand inside? Shipping costs were almost more than the brush!
