Where can I get the green striped pads? I want to build up a nice inventory of different pads and solutions.

Scrubmeister.com Excellent supply.com are a couple of good places to look around

Or jondon. Or any local janitorial supplies retailer.

Direct Mop Sales has them at $14. and some change if you want to try 1 first before you buy a case. But all those other places have them too.
