Review on Sudz Budz Premium Jumbo Foam Grid Sponges 2pcs | Cross-Cut Car Wash Sponge 🧽 | Multi-Use, Easy Grip, Scratch-Free | Durable, Soft, Absorbent | Car Cleaning Sponge for All Surfaces by Jeff Addison

I like the size of the sponge and the price, basically two in one. However, I'm an auto parts enthusiast and have only had trouble using this with ONR. I soaked in two different sand proof buckets for 30 minutes, just to be on the safe side I used double the dilution rate for the ONR. I used a maximum of two passes, one for each side. This sponge just pulled everything through every flat plate on my truck. I used to have 8-9 out of 10 colors, now I desperately need a fix. I am very picky about the products I will use on my own truck as well as customers' vehicles and I would not use this again on mine. This might be fine for something like a boat or motorcycle, and it might also work with a high-slide automatic foam or shampoo, but it won't work with a no-rinse conditioner. I can post photos of the scratches if they show up on camera.
