For thick buildup on porcelain surfaces, you'll need to use something a little more heavy-duty. Use a product like Comet or Ajax that comes in powdered form. The small particles will be able to penetrate deeper into stains that have set up on the surface of the tub to remove them. Powdered cleansers contain chemicals known as surfactants which have mild abrasive properties. This makes them much more effective for addressing hardened, stuck-on residue. Apply abrasive cleansers sparingly. For most jobs, a single canister be enough for a single thorough cleaning. Alternately, tough stains like rust and hard water residue can be treated with a mixture of hydrogen peroxide and cream of tartar. Blend the two ingredients together until they're about the same consistency as cake frosting and spread them directly over the stains. After 10 minutes, buff the stains with a nylon brush or pumice stone until they're erased completely. Homemade concoctions like hydrogen peroxide and cream of tartar will be preferable for those who are wary of the health and environmental effects of chemical cleaning products. Hydrogen peroxide will also help treat age-related discoloration and lighten the finish of the tub. A moderate dusting should be enough to deal with most messes. The powder won't stick to the surface of the porcelain on its own, but when combined with a liquid it will form a paste that can be spread directly over stains. Be sure to cover the bottom of the tub, where accumulated mold can become a slipping hazard. Spray purified or ordinary tap water onto the cleaning powder. With the addition of moisture, the powder will take on a thick, foamy consistency. Rub this paste into the stains and give it about half an hour to take effect. You can also wet a clean sponge or washcloth and use it to rub in the cleaner until it thickens. Another option is to wet the tub before you apply the cleanser. Spray the tub with the shower head or fill a cup with water and pour it around the inside of the tub. Be careful not to add an excessive amount of water. The cleaner won't be as effective if it's too thin. Since porcelain has a hard, durable finish, you can scrub it safely with an abrasive implement without worrying about scratching it up. For best results, equip a pumice stone or stiff-bristled scrubbing brush. Work on the stains until they're completely erased, then rinse the tub with clean water and let it dry before using it again. If you don't own a dedicated scrubbing brush, you can use the rough green side of a kitchen sponge. Never use steel wool or any similar material to scour a porcelain tub. Even though porcelain is scratch-resistant, this can be enough to cause permanent damage to the finish.

If there are any pets, children, or others in the area where the glass broke, move them out of the area. Close any doors leading to the area where the cut glass is located, and block any open entrances. If there are any children or animals near the glass, get them out of the area where the broken glass is. Make sure to check children and pets for cuts and scratches. Broken glass is sharp and will cut through your skin. To clean up broken glass, make sure you're wearing rubber gloves. Always wear shoes when you're near broken glass. Never kneel on areas where broken glass is located. Glass could cut your knee. If you don't have gloves, pick up glass using tongs or forceps. Never try to pick up glass with your bare hands. Carefully put each piece of glass into a empty coffee tin, or a plastic container thick enough so that the glass doesn't cut through. If you don't have anything that glass won't cut through, such as a plastic bag, wrap the pieces of glass into thick layers of newspaper, then put the wrapped glass into a plastic bag. The newspaper needs to be thick enough so that the glass doesn't cut through it, reaching the plastic bag. Once you've picked up the individual shards, you'll need to sweep or vacuum the smaller pieces from the floor. If you don't have any larger pieces, this might be your first step in cleaning up broken glass. Be sure and shake your broom well into a paper bag to release any smaller pieces of glass that might linger. Some experts recommend not using a broom, as tiny shards of glass can linger in the bristles of the broom. Consider trying one of the broom-less methods below to clean up your glass if you are wary of using a broom. Be aware that sweeping doesn't remove the small, sharp fragments of glass from most floors. Sweeping can offer the illusion that the glass is gone, when sharp fragments still remain. Continue to keep pets and children out of the area until additional steps are taken to clean the broken glass off the floor. Sucking up pieces of glass with a vacuum cleaner may seem tempting, but it may ruin your machine. In addition, if any glass fragments remain in the vacuum hose, they may fall back out when the vacuum is turned off. If the broken glass comes from a broken CFL or other mercury-containing lightbulb, then vacuuming might spread mercury-containing powder or mercury vapor. If you do use a vacuum, cover the hose with a stocking or sock. The air sucking in will collect the glass fragments, and then you can carefully dispose of the glass-covered cloth. If you've broken glass onto a carpeted surface, you won't be able to use the methods above. Once you've cleared the area of larger glass fragments, use a small scrubbing brush to agitate the carpet fibers. This will result in glass pieces rising to the surface of the carpet. When you're finished scrubbing the area well, use duct tape to lift any remaining glass pieces. You should carefully dispose of the duct tape in a double-wrapped plastic or paper bag.

If you expect to have to bring Gardenias in over winter because you live in a cold climate, do yourself a favor by planting them in lighter container materials. You may otherwise find it too difficult to try to bring the heavy pots in for the winter. Light materials include plastic (you can put the ugly plastic pot inside a more attractive pot). You could also put your pot on a pot trolley to make heavier pots easier to move. In zones 6 and cooler it's important to bring Gardenias outside only in warmer temperatures. The rest of the time they will need to be in heated spaces indoors. Zone 6 temperatures can drop down to -10 degrees Fahrenheit (-23.3 degrees Celsius). A general purpose fertilizer given over six weekly intervals is ideal. Reduce watering over winter but do not allow the plant to dry out completely.

Set an 8in (20cm) nonstick skillet on the stove and put 1 tablespoon (14.8ml) (14 g) of unsalted butter into it. Turn the burner to medium-high and tilt the pan a little so the butter coats the skillet as it melts. You could also use a seasoned carbon steel pan. Bring your serving plate over to the skillet. Slowly tilt the skillet up and over the plate so the rolled omelette lands on the plate seam-side down. Serve the omelette while it's hot. You could garnish it with more fresh herbs if you like.
