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.
Step 1. Preheat your oven to 325 degrees Fahrenheit for a pot roast from the round; 425 degrees for a pot roast from the chuck; and 350 degrees for a pot roast from the rib. The weight and type of roast determines the cooking time; you should cook a roast until its internal temperature is between 135 and 150 degrees F.enerally, the final internal temperature, according to the U.S. Department of Agriculture, for a medium-rare pot roast should be around 145 degrees F after 15 to 20 minutes of standing time. The final internal temperature for a medium-done pot roast should be around 160 degrees after 15 to 20 minutes' standing time.
