3M Contour Surface Sanding Sponge, 4.5-in by 5.5-in by 0.2-in

I dug out my old HO train set for the kids to play with. The brass track were oxidized, and I did a little research on what was the best way to clean them off and get them shiny again. One website recommended these 3M sanding sponges so I got one. It's perfect. Cleaned those tracks up perfectly, they look like new and the train is running again. The sponge is soft and easy to hold. My girls helped clean the tracks and were taking turns doing it. All in all I'm very happy with this.

Not much to say except this is exactly what I was expecting. The item can sand directly, but I intend to also use it as a sponge wrapped in my choice of sandpaper. Doing it this way allows me to hand sand and not leave waves because of the odd pressure from my fingers.

3M is a fantastic company and makes high quality products. However, after frequent use the sponge does start to chip apart. Sometimes I'm sanding drywall or wood and the sponge becomes null or eventually the paper around it breaks off. I wish it was like a true sponge and the entire object could be utilized for sanding. Overall, It works great for small projects or finishes. Easy to use and somewhat durable.

These sponges are my absolute favorite to keep on hand for random projects. I have been mostly using them for sanding drywall repairs and trim filler. Great quality and very versatile. I like to make sure I have an extra set handy if I ever need a nice sanding sponge. I don’t know why “sheerness” is a rating for these, it’s a sanding sponge... but anyway, can’t recommend these enough! They stand up to a lot and last a long time!

Previously used drywall sandpaper mesh but tried these and boy do they work well, hold up for a long time and the shape makes it easy to get into corners and tight spaces.

I've used these both to smooth between coats of urethane and to break the gloss on final coats and they work great. Very fast consistent smoothing/dulling plus they last a long time and can even be washed out when they get loaded with dust. Cost a bit more than some other brands but work better and last longer in my experience.

These are awesome used for sanding drywall in closet bedroom roof corners and where wall meets roof. Coukd not do job without them!

I will be buying this again. No complaints, they do what they need to be doing, sanding. They can be rinsed off, dried and used again.

Perfect for corners great fit for hands comfortable

Las esponjas no dicen 3M en ningún lado, todas vienen con los cortes mal hechos y chuecos y todo eso en conjunto le hace desconfiar. Tengo una que compre por separado y siento diferencias hasta en la consistencia de la esponja

Good quality. Really pricey though, hope it reduces significantly in the future

Very helpful

Works great.
