I am looking for a cleaning supplier that is zero waste. We currently use 4L, 10L to refill our 1L bottles. Our goal is to become zero waste ourselves by not having to buy plastic containers every time we need a refill. Our current product supplier will not agree to allowing us to refill our larger containers. Perhaps it is time for find a new cleaning supplier. If anyone knows of one preferably in Canada or the United states, that would be great.
