Chemspec Furniture Blocks should be used to prevent furniture stain marks when cleaning under large sideboards or pianos etc. These blocks are made of high density styrofoam and are stronger than the usual white version.
I cant see how it is possible to do the job properly without these blocks. They are much tougher than the white blocks. The great thing is some of my customers save them up for me once they have been used and they are tough enough to use again!

A product to save you problems with dye transfer from wooden furniture etc. I prefer these high density blocks, as the cheaper ones tend to crumble.
