bersionr 0 Report post Posted May 24, 2009 Hi , Anyone experience having these brown sand-like particles on the floor next the wooden wall skirtings? After each wipe, about less than an hour, they form again. Any idea what it is? I bought my new condo 2 yrs ag, this is the 1st time i encounter this. pls help~ ber Share this post Link to post Share on other sites
