Monday''s Ask the Experts question from a cleaning professional on theInternational Custodial Advisors Network(ICAN)"Ask the Experts"page:We have a newly constructed facility — opened August 1. The custodial agreement reads "The dry foam cleaning method shall be used when it will thoroughly remove all streaks, stains, and spots.
