Jumbo Cross-Cut Grid Sponge 3-Pack | All-Purpose, Durable, Extra Absorbent Sponge for Cleaning | Large, Easy-Grip Car Cleaning Sponge | Soft, Scratch-Free Multi-Use Sponge

I use these with onr and they perform very well.

These are large and thick, and I like the cut outs on the side for grip. They work well for large flat exterior car surfaces, but are not small or flexible enough to go in between railings, cracks and corners, etc. That said, I would buy them again. They speed up the exterior cleaning process considerably. They also hold a lot of water.Be aware however that all sponges require some "wear-in" time, during which they will slowly become more flexible, and useful.

Worked good for a while then started to fall apart. Some of the individual squares fell off when scrubing with the sponge, one of the sponges ripped in half pretty quick. They do a decent job if you are using them gently

One of the sponges was deformed but useable they all were cut such that the edges are uneven and a lot of excess material was hanging off and had to be trimmed. The material is good and they work as intended.

I use these with ONR to wash my car. It helps with a nice quick wash. I like the fact that they are bright green so that the dirt shows up clearly.They work the same way as the more common fuzzy mitt we get from the auto parts store. The fuzzy mitt has the advantage of being able to toss it in the wash after it's used.
