That's just the nature of acrylic solid surface. Acrylic (or polyester) resins are basically solid plastic and not scratch resistant (or heat resistant). Dark colors show the scratches a lot more than light surfaces because the acrylic matrix always shows as white when scratched. Glossy surfaces show the scratches a lot more than matte surfaces as well. Now, those scratches can be professionally buffed out when they get too bad, unlike laminate countertops that when scratched are ruined. But this isnt' something you'll want to spring for every year as it's in the $300 range for an average counter. Even then, deep scratches will remain.

Use cutting boards and trivets and try not to slide things across your counters. Pick the cups up and put them down, etc.

Yes,we have been using cutting boards. Used them when we had laminate,granite, and now with LG.You don't dare to slide anything across it. A bag of ice cubes left a mark after it had been moved slightly. And here i thought I was getting something fairly maintainance-free. Not so! Our counter guy will redo them for about $90 here in Western WY. Plus I'm short so I think I see scratches more easily!

How do I get the stains out of my sink. Someone told me I could use bleach. If so how much do I use. I am sure it probably should not be used full strength.
