He told me this when we were building our house. I've taken his advice and my kitchen floor is as shiny today as it was the day we had it put in 13 years ago. You can guess which one is the cheapest. Don't assume any company is going to give you the cheapest without asking. But, then I had all this shredded paper to get rid of.
Shredded papers are excellent to use as a packing material when moving.
I have also used shredded paper for filling the bottom of gift baskets, used it to soak up spills in the garage and mulch for around plants. Don't use your shredded sensitive documents in gift baskets and for mulching don't use plastic window envelopes, no colored paper or colored ink. The cost is very low. Before you reach for that stain pre-treater try soaking the item in cold water. Recently my toddler son took a terrible fall and was bleeding profusely from his mouth.
