Q: Sodium lauryl sulfate (SLS) can be found in some commercial toothpastes and mouthwashes. SLS is often used as a cheap filler to help toothpaste thicken and foam up. But this additive has been shown to increase the likelihood of developing canker sores in your mouth. Read the labels on toothpastes and mouthwashes to make sure they are free of SLS before you use them or search online for brands that specifically do not contain SLS. You can also follow good oral hygiene by choosing a soft bristle toothbrush to clean your teeth. Try to brush your teeth twice a day and after every meal. This will reduce the presence of bacteria and food particles that may cause canker sores to develop. Using a soft bristle brush will also prevent irritation in your mouth. Irritating your mouth with hard brushes can lead to the development of canker sores. Floss once each day to prevent food particles from staying in your mouth. These food particles can lead to oral health issues, including canker sores.  Get in the habit of flossing before bed as well so your mouth is clean and free of bacteria or food particles. Flossing more than once daily can be harmful to your gums. If you have braces or a retainer, make sure it is not rubbing or scratching the inside of your mouth. Poorly fitting dental equipment can lead to the development of canker sores. Talk to your dentist if you feel your dental equipment is irritating your mouth. If you have braces that are rubbing against your mouth and causing sores, try using dental wax to cover sharp edges.
A: Use toothpaste that does not contain sodium lauryl sulfate. Brush with a soft bristle brush. Floss once daily. Make sure your dental equipment fits properly.

Q: Books should be lined up vertically on a shelf, rather than stacked or set horizontally. Improper storage such as stacking can cause the binding to break down, resulting in the dissolution of the book’s structure. Books should be placed alongside similarly-sized books to prevent bowing. Placing large books alongside smaller books could, over time, encourage the top of the cover to sag outward, resulting in a curved, irregular appearance. If you have a wide array of sizes and shapes, group them according to size as much as possible, using thin metal bookends to corral each size. Spacing books loosely will allow them to lean, resulting in weak binding and warped covers. Books should fit snugly against each other, but should not be packed in tightly, as this, too, could damage the binding. Ideally, books should be spaced in such a way that they all stand upright, with enough wiggle room to allow a small finger to wedge between them.
A: Place books upright. Group according to size. Space books carefully.

Q: The back of your toilet seat is usually connected to the toilet with two long screws that run through the porcelain at the back of the bowl. The screws are secured by two nuts underneath. In the front of the cover, look for a small groove that is designed to help you pry up the cover. Then, use a small screwdriver to pry up both the seat and the cover. In cheap toilets, the screws are made of plastic. Most toilets, however, use steel screws, and more expensive models may even use brass or stainless steel. Be especially careful with plastic screws! If the seat is loose, then it may wobble back and forth, in and out of alignment with the rim of the toilet bowl. Straighten out the seat so that it rests evenly atop the bowl. Consider sitting down to test it out for comfort. Turn the screwdriver clockwise to tighten. Remember: "righty tighty, lefty loosey." There's usually a nut with a wing attached to prevent the nut from turning. If there isn't,  hold the nut with a rag while you tighten the bolt. Decide which screwdriver is the best fit. Make sure that the screwdriver head is big enough to fit into the notches of the bolt head. If the screwdriver is too small, then the bolt will not turn. The friction from the slipping screwdriver will quickly wear down the bolt and make it unusable. If the bolt keeps turning without tightening up, clamp the nut underneath with a small pair of pliers. Clamp onto the end of the nut, and hold it steady as you screw the bolt. Once you have twisted the bolt several times, the wing on the nut should prevent it from turning anymore. To loosen the nut, spray it with WD 40 and wait 5 minutes. When the bolt feels tight, give it one more quarter rotation so it's extra secure. Once the seat does not wobble back and forth, push down the lid. It should click closed.
A: Find the screws and pry up the cover. Center the toilet seat on the toilet. Tighten the bolt. Apply tension. Keep screwing until the seat is tight.

Q: This is a great idea if you need to easily fill many lotion bottles at once, and there are many different types of professional filling machines available. Search online for “Manual lotion filler for sale” to review different options. Select a machine that works for your needs and fits your budget. Most manual fillers feature a main fill tank, filling tip, and hand lever. The main tank is often located at the top of the machine. Take off the lid, and pour your lotion inside.  You can use a spatula to help you scoop the lotion if you are having trouble. Every machine is slightly different, so read your instructions to ensure you are filling the tank correctly. The filling tip is the thin metal tube where lotion is dispensed. Lotion can drip from the filling tip if you leave the hand lever in the down position for just a second or 2. To avoid this, simply place a bowl underneath the metal tip. Then, any extra drips will fall into the bowl and you can easily wash them away. This way, lotion does not wind up on your bottles. To pour your lotion into the bottles, hold the lotion bottle up to the filling tip, and place the lotion bottle around the tip. This prevents the lotion from spraying as it comes out. In addition, it ensures you do not miss the tip of your bottle while filling it. Hold the lotion bottle in 1 hand. Then, pull down on the lever with the other hand to release your lotion from the machine. To stop the flow of lotion, move the lever back to the upwards position. The lotion will come out quickly. If you are filling a small bottle, 1 pump of the lever will likely fill your bottle. If your bottle is not completely full after 1 pump, then pull down on the lever again to release more product. Lift up on the handle when you reach the top to stop the lotion from dispensing. After your bottle is full, continue filling all of your bottles.
A:
Purchase a manual filling machine online. Fill the main tank of the machine following your instructions. Place a bowl underneath the filling tip to catch any spills. Position the lotion bottle so the filling tip is slightly inside the opening. Use the pull-down lever to start and stop the flow of lotion. Fill the bottle until you reach the top.
