Hey
It is removeable technically but in realitiy no.. Its cut in exact pieces to cover the entire floor like large tiles. they are very heavy/awkward and it took me 2 days to lug them down and set them up. So I dont want to remove them. If I do remove them..... it will be to burn them

No I have mopped them with water etc.. and scrubbed and scrubbed... so I am thinkint that hosing them down wont work much better.

I was thinking maybe a floor cleaning machine or something? but that is a lot of money to rent..I was hoping someone would have a "magical" cleaner that is industrial and works or something.. also thinking of using an angle grinder with brush attachment or something along those lines...
Anyways its a pain..I spend thousands on my gym.. its great except the floor looks like something from a barn,,too much dirt staying in the pores of the matts... I want it to look fresh and clean.....there has to be a way. I am sure members will have some more ideas. I apprecaite the idea of hosing....
thx
Jim
