Query: Damages metal and loses soap suds

I just switched sponges about 4 days ago to this sponge. I have noticed a HUGE difference, and I don't like what I've noticed. First, this sponge requires more soap than my previous sponge. I don't know why, but I have to add soap more frequently to keep it soapy. Also, I've noticed that the scrubber side damages my pots, pans, and appliances. I use to be able to lightly scrub on my trash can and toaster with the abrasive side of my old sponge, and it never damaged the surface. Now I have incidentally damaged those and the bottoms of my pots and pans as I scrub food. I haven't added more pressure, but for some reason this sponge is stripping away at the metal when my old one didn't. Time to switch back!
