Using the ASI 1000 Circular Countertop Waste Chute is easy. First, find a countertop opening with a 5 - 3/4 - inch diameter. Apply a silicone sealant around the opening and then place the chute in it, making sure it's securely in place. Once it's properly sealed, position a waste receptacle directly under the chute to catch the trash. When using it, just drop your paper waste into the chute. As for maintenance, regularly clean the chute with a mild stainless - steel cleaner to keep its No. 4 satin finish looking good. Avoid using abrasive materials that could scratch the surface. Also, check the silicone sealant periodically. If it shows signs of wear or damage, replace it to ensure the chute stays firmly installed.
