Chemical Guys Boars Hair Detailing Brush - Gentle Scratch-Free Cleaning for Wheels, Grilles, Emblems, and Interior Surfaces - Versatile Multi-Purpose Auto Detailing Brush for Deep Cleaning - Acc_S90

Great brush set. I had to remove a stain from an interior seat and it worked excellent. I was so impressed. I’m gonna buy the outside ones. Also chemical guys has some really good stuff.

As much as I am not always trying to buy the name brand of things, I have to absolutely admit that these brushes can withstand a lot of abuse and different types of cleaners. Give them a good rinse after each use and they will last a very long time. Also, with the advancement of all purpose cleaners like the red MAD Acid, you only need to use the brush to agitate the dirt instead of thinking you need to scrub.

These brushes are perfect. The hairs don't shed or fray and they really do boost your efficiency when cleaning. They allow you to clean all the hard to reach places that often get overlooked. Perfect for cleaning cup holders, door panel pockets, door jambs, engine bay, emblems, badges, vents, etc. You don't realize how useful a cheap little brush is until you use one. It says these are for exterior but obviously they work great on interiors too. I can't see why you'd ever need a separate set of these brushes specifically for interior work. The bristles are about as soft as a paintbrush and are nowhere near stiff enough to scratch any interior surfaces. If it's safe for paint then it's safe for plastic, upholstery, metal, leather, etc. I guess the idea is that if you use it on your exterior first then switch to the interior you might have trapped some dirt/grit that you don't want in your interior but all you have to do is clean the brush which takes 10 seconds. If you wanted to you could just designate the large brush for exterior work and reserve the 2 smaller ones for interior.

These brushes aren't bad. Although I don't like long-bristle brushes, these reach into areas that you'd otherwise be leaving alone while detailing. Something to note, the picture is inaccurate - the Goat Boar's brush no longer features a metal ferrule to hold the brush assembly together, rather it's black plastic. In my experience they hold up better. The metal version would get loose the first time the wood became saturated. I still have a couple, and a couple of the newer-styles - and I've gone through about 5 of these brushes in total. It is my go-to brush for lug nut holes, intricate wheels, dashboards, interior stuff, but only if they do not require heavy scrubbing. The bristles are boars hair, and semi-fine. They are flexible and have handled LOTS of chemical abuse - wheel acids, APC's, degreasers, and of course - soapy water. I try to keep a good stock on hand. I do not hesitate to use this on paint, either - it's especially good (see below, it's important) as a wax removal brush. I frequently detail vehicles that have previously been detailed at a dealership/cheap detail house. They generally leave buffer material and/or wax/polish in between body panels and lenses, and this is what I choose first to remove it! If it doesn't work dry, then I use some soapy water during the wash process. Excellent for cleaning around headlights/lenses, and the grille areas where a wash mitt doesn't get to. Something you should do, is buy some Temflex from home depot - it's a self vulcanizing rubber tape, generally used in the electrician industry. It stretches out a considerable amount, and I use this to wrap the bottom of the brush, over the bristles by about 1/2" or so. This allows you, depending on tension, to 'tighten' the bristles into a slightly smaller, yet considerably tighter - and more useful brush. Of all the brushes out there, this is my favorite.

Another great product from Chemical Guys. Super source for car care products.

These interior brushes are absolutely fantastic and 1 of 19 purchases that I made from the Chemical Guys line. I saw complaints that people had, but thought I’d take a chance and glad I did. Sturdy handle, sturdy bristles, gets in nooks and crannies you didn’t think you could clean, you might not need all three brushes but even one of these is worth the price. I’m a fanatic when it comes to keeping my vehicle clean inside and out, I don’t want to see dirt and debris and when I use these inside, I noticed they work very well not only in little crevices, but in the vents, in the nooks and crannies of the underside of the seats. I couldn’t get a vacuum down along the side of tte front seats to clear debris or lint off, but I was able to stick these down there easily and swipe the area clean. Highly recommended, I also purchased the exterior ones and expect them to do just as great a job.

I've been using these types of brushes for years usually horse hair but that's not acceptable today. Then I found these they work better than the old brushes. Very glad with them.

These brushes are good for getting dust out of small spaces. I also find them super useful when I put soap on them and use them on an exterior, almost honeycomb like, detail on the rear end of my car. It's impossible to get the dirt out of this area with just a rag or mitt, but these brushes get it done.
