Scotch pads??

they probably would scratch acrylic and im not sure how big of deal it is i have heard to be careful because alot of household cleaning pads have chemicals on them so bacteria cant grow dont know if it would harm anything or not but imo fish tank cleaning sponges are cheap enough
I've never used them, and never would. Their are too many cheap alternatives. In my opinion its not worth scratching an acrylic tank over a few bucks 
Glass...Si
Acrylic...No
I use scraps from cutting the 6X9 pads that I use in both canister and HOB.
I took a 2" wide plastic putty knife, attached it to a broken fishing rod(tie wraps) and that is my glass scraper. About once a month, I use a file to put a good edge back on it.
What really makes it work is the small bend I put in the end of the putty knife. About a 15-25deg. bend. Hot water and a vise made the bend.
I attach the pad, folded over the end, and held by another tie wrap.
Hmmm, seem to use allot of tie wraps.

used them on glass when they are wet, and also used the green ones in diy filters, not sure about the other brands, but the green scotch brand are ok and no additives.
Well, I have been using them on my small glass tanks for some time with no problems, but I haven't tried them on my Acryllic tank yet for fear of scratching it....hense the post here 
Thanks for your input guys.

There are also the blue "no scratch" scotch pads. Those might work on acrylic. But to be safe, test in an inconspicuous spot (back or bottom) and see what happens. It eels like the blue obes are the same consistency as the pads they sell for acrylic tanks. But like I said, its better to test a small spot first, just in case.
green NO!, red NO!, light blue maybe!? they are color graded but i would not use them any how i use the red and green ones to etch aluminum they will destroy you acrylic and over time will wreck glass too.
i agree with the red no, nut the green are fine as long as they are wet, even the sos pads won't scratch when they are wet, i restore a lot of old cars and have done a lot of old tanks and i use the metal sos pads and as long as you keep water on them they do great on glass, just gotta be careful because of the soap they have on them.
