article: Some manufacturers recommend closing the air controls during cleaning. Others recommend leaving them open. And some manufacturers prescribe (and proscribe) the use of particular cleaning products. Consult your manual to discern the best way to proceed. Turn the water on. As the tub fills, add cup (118 milliliters) of mild dish soap and 4 cups (1 liter) of bleach if your tub is really gross. If your tub only needs a mild cleaning, add just 2 cups (1/2 liter) of bleach. If the water from your tub's faucet does not reach at least 140 Fahrenheit (60 Celsius), you'll need to boil some water on the stovetop until it reaches the appropriate temperature, then transfer it to the tub. Turn the jets on for 20 minutes. At the end of the 20 minutes, empty the tub by pulling the drain out of the bottom. Turn the water on. This time, though, you need only fill it with lukewarm water (even cool water should work just fine). Don't add soap or bleach. Turn the jets on for another 20 minutes. By this time, all bleach residue should be thoroughly drained. Just to be sure, though, wipe the inside of the tub down with a towel. This will prevent skin irritation should any bleach residue remain.

article: It's tougher to figure out square roots of numbers that are not whole. But it's possible. Let's say you want to find the square root of 20. You know that 16 is a perfect square with a square root of 4 (4X4=16). Similarly, 25 has a square root of 5 (5X5=25), so the square root of 20 must fall in between 4 and 5. You could guess that 20's square root is 4.5. Now, simply square 4.5 to check your guess. That means you multiply it by itself: 4.5X4.5. See if the answer is above or below 20. If the guess seems off, simply try another guess (maybe 4.6 or 4.4) and refine your guess until you hit 20. For example, 4.5X4.5 = 20.25, so logically you should try a smaller number, probably 4.4. 4.4X4.4 = 19.36. Thus, the square root of 20 must lie in between 4.5 and 4.4. How about 4.445X4.445. That's 19.758. It's closer. If you keep trying different numbers using this process, you will eventually get to 4.475X4.475 = 20.03. Rounding off, that's 20. This process also starts with you trying to find the closest whole numbers that your number falls in between. Then, divide your number by one of those square root numbers. Take the answer, and find the average of it and the number you divided by (average is just the sum of those two numbers divided by two). Then take the original number and divide it by the average you got. Finally, find the average of that answer with the first average you got. Sound complicated? It can be easiest to follow an example. For example, 10 lies in between the 2 perfect square numbers of 9 (3X3=9) and 16 (4X4=16). The square roots of those numbers are 3 and 4. So, divide 10 by the first number, 3. You will get 3.33. Now, average the 3 and 3.33 by adding them together and dividing them by 2. You will get 3.1667. Now take 10 divided by 3.1667. The answer is 3.1579. Now, average 3.1579 and 3.1667 by adding them together and dividing the sum you get by two. You will get 3.1623. Check your work by multiplying your answer (in this case 3.1623) by itself. Indeed, 3.1623 multiplied by 3.1623 equals 10.001.

Remove existing caulk from your work surface. Clean the surface. Use blue painter's tape to mask off areas and ensure straight lines."
article:
There are two main types of caulk silicone and acrylic latex. Silicone caulk is a completely waterproof and flexible sealant. It will bond with a lot of different kinds of surfaces. Silicone is a good choice if you're caulking outdoors, or wet indoor spots like around shower stalls and bathtubs. It's quite expensive and doesn't do well in high-traffic areas. Silicone caulk is ideal for areas of high moisture that need to remain mildew-free. Silicone caulk can also be useful when you need to adhere surfaces, like fastening countertops to walls or putting a top on a vanity. Silicone caulk is typically only available in three shades clear, white, and almond. Silicone caulk cannot be painted over. Acrylic latex caulk is easier to use and cheaper than silicone. It can be used for a wider range of projects and it comes in a rainbow assortment of colors to match bathtub and sink glazes. Acrylic latex is water-based so it's best used indoors. It is not as durable as silicone caulk and won't last as long. Since acrylic latex is water-based, it is possible to paint over it. Acrylic latex caulk shrinks up more than silicone. It also dries much harder. Unless specifically noted on the packaging, latex caulk isn't suitable for any exterior surfaces. Acrylic latex caulk is not suitable for tiling or areas with direct sunlight. Old caulk must be removed before you add more. Use a utility knife, razor scraper or painter's tool to cut away existing caulk. Use quick, sharp strokes. Keep in mind that metal blades aren't ideal to use around plastic fixtures. Use a tool with a plastic razor blade, which you can get at any home improvement store, to avoid damaging the plastic. For concrete and masonry applications, use a wire brush for removal. Home improvement stores sell caulk remover products that will chemically remove old caulk. Keep in mind that these products will damage plastic surfaces. For silicone caulk, you may just need to rip up enough that you can grab an end with a pair of needlenose pliers. Then, you can pull the caulk out in one long strip. Use a brush or vacuum to remove any remaining debris from the work area. Scour the surface clean with a dry, nonabrasive sponge or pad. Use rubbing alcohol to remove soap scum and body oils from a bathtub or shower stall. Dry the area completely before you begin caulking. Both kinds of caulk need a clean surface, but if you're using silicone, it's imperative that you remove all debris and residue from the surface before you begin. For silicone clean up, soak a rag with mineral spirits (such as turpentine) and wipe the surface down with it. Then use a damp rag to wipe the surface down again. Apply strips of the tape to protect any surface area where caulk shouldn't appear. Put them down vertically on either side of the area you plan to caulk. The painter's tape acts as a guide to ensure your caulk lines are straight and uniform. The end result will look more polished and professional if you use painter's tape.
