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 Roast for 1 hour in the preheated oven. 2  Turn the oven off and leave the roast inside. 3  Do not open the door. 4  Leave it in there for 3 hours. 30 to 40 minutes before serving, turn the oven back on at 375 degrees F (190 degrees C) to reheat the roast. 5  The internal temperature should be at least 145 degrees F (62 degrees C).
