soapy scrubber on a pole ,followed up with a clean scrim draped over the same scrubber . i did one con like this the other week and it made light work of what could have easily been a nightmare, as the lady had immac soft furniture and nice mats in there. 3 of us each with a 4 foot pole, did the job in about 15 minutes that included moving tall glass ornaments as we moved slowly in a circle ,the dance of the big spiders !
