Years ago I started using the name brand "Magic Eraser" and paid about $6-7 for a box of four.
Later, I discovered the cheap version at the dollar tree, 2 for $1. I was flyin high.
HERE is a post I did with a quick before/after of my kitchen sink using this and another productAll along, I'm thinking, gosh, what IS this material? This magic material? After some simple google work, I found my answer.
They are made of melamine foam. Same stuff that has been used as insulation in pipes, ductwork, and sound proofing material. Sounds appealing huh.
So no more paying a whole dollar for 2. No no, ladies and gents, I give you $8.90 for 30 melamine foam pads. THIRTY. I go through one to two a week. ( I should probably start cutting them in half to make them go further ) It's via ebay and it's a reputable seller, in the USA. Click HERE to go there.
I may be giving you new information or I may be the last to know this !
If you havent used these yet, here's a convincing list:
