Post by ccs06 on Nov 12, 2008 at 7:47am. Any advice for cleaning ceramic tile with textured grooves in it? The tile also has little pit holes in it to that the dirt just gets in and sticks as well as along the grove lines. This is in a high traffic area so it is dirty nightly. I started cleaning with a scrub brush and then moved to a handled angled brush to get in the crevices better, but it takes forever and it never looks absolutely clean.
In an oven heated to 275 degrees you cook a roast for 28 minutes per pound. Therefore the estimated cooking time for a 4.8 pound roast is 134 minutes or 2.23 hours.
1 Preheat oven to 325Â°, place roast in pan and place on upper oven rack. 2  Cook for 25 minutes per lb for medium or approximately 50 to 60 minutes. 3  Use a meat thermometer to check doneness-should read 140Â° for medium. 4  Remove from oven, cover with foil to keep warm and let rest for 15 minutes before carving. Mix together rest of ingredients and rub over roast. 2  Let set for one half hour. 3  Preheat oven to 325Â°, place roast in pan and place on upper oven rack. 4  Cook for 25 minutes per lb for medium or approximately 50 to 60 minutes. 5  Use a meat thermometer to check doneness-should read 140Â° for medium.
