Excellent polishing cloth for glass. Microfiber insures removal of spots & smudges. Highly recommend.SINLAND microfiber polishing cloth (20"x25") along with a Kitchen Mama Silicone Long Spatula Scraper (with a narrow flare, at one end & for scraping jars), together have another practical use:Kitchen Mama's Long Spatula (with flared, but narrow end) is perfect tool, due to flared & straight ends, for cleaning & drying inside a large, wine decanter. Use straight end to carefully stuff a large, paper towel down the decanter's neck (after washing with soap & water & draining excess); then, use flared end (narrow enough to easily insert) to twirl paper towel, getting it to flare & absorb remaining water inside decanter's bowl. By twirling flared end, it will then assist pulling paper towel out of the decanter. Takes patience, but easy & works very well.Long Scraper can then, be used in same way to insert, twirl, & remove a SINLAND microfiber polishing cloth (20"x25") to complete final drying-polishing of decanter's interior. Works very well.{Combination of these 2 "tools" insures a wine decanter will not have unsightly, water spots. Start to finish takes about 10+ minutes. Having care in handling decanter, recommend using disposable latex gloves for tactile grip of decanter.}
