article: If your muffler is not welded in place, it will be secured using muffler clamps.  Spray a rust penetrator like WD40 onto the fastening hardware to break through some of the rust and grime that may have seized the nuts in place.  You may need to spray the bolts and let them sit a few times before they are able to be loosened. You can purchase rust penetrator at most auto parts or large retail stores. Once the fasteners have been thoroughly soaked in rust penetrator, use a wrench to remove the nuts holding the exhaust clamp in place.  Make sure to use a socket or wrench of the correct size, as exhaust fasteners are prone to stripping or breaking.  If you intend to reuse the muffler clamp, you may want to spray it with more rust penetrator as you work it loose. You can purchase replacement muffler clamps at most auto parts stores if they are too rusty to be reused. Because the muffler and the piping have been held together with the exhaust clamp for so long, they may not come apart easily once the clamp is removed.  Spray some rust penetrator where the two pipes meet and try to work them away from one another until they slide completely apart.  If the pipes are rusted together, you may have to cut the pipes apart. If your muffler was welded in place, you will have to cut the pipes apart. The muffler will have metal prongs sticking out of the top that slide into rubber eyelets below the body of the car.  You may have to push the prongs through the rubber with a bit of force to get past the initial ridge.  The rubber will prevent the muffler from rattling inside the cabin of the vehicle once the muffler is completely installed. There should still be enough play in the rubber mounts to allow you to move the muffler around as you connect it to the exhaust pipe. Spray exhaust sealant on the pipe coming from the exhaust and the pipe it will connect to on the muffler.  This will help establish a seal between the pipes and prevent any exhaust from leaking at the joint.  Refer to the instructions on the exhaust sealant to know how long to let it cure. You can purchase exhaust sealant at your local auto parts store. Slide the pipe from the muffler over the existing exhaust pipe.  The muffler should rest directly below the rubber eyelets its mounted to, so the eyelet should hang straight up and down when the pipes are joined properly.  If the two pipes feel loose or can be wiggled, you will need an adaptor to match the correct size.  Most exhaust piping comes in two or two-and-a-half-inch diameters. You will not be able to seal the wrong size pipe onto another pipe, but adaptors for most diameters can be purchased at hardware or auto parts stores. With the piping seated properly, slide a muffler clamp over the area where the muffler pipe overlaps the other.  Use a hand or socket wrench to tighten the clamp until it is not possible to move the pipes back and forth at all.  You may want to use a half inch drive wrench to tighten the clamps to make sure you have enough leverage to tighten it sufficiently. Be sure you tighten the clamp where the piping overlaps, otherwise you may not create a solid seal.

Mix the dry ingredients together. Cover the spices with salmon. Weigh down the salmon. Leave at room temperature for six hours. Refrigerate the fish for one to three days. Remove the salmon from the container. Serve with mustard dill sauce."
article: Gravlax, also called gravad lax, is a traditional Nordic dish which uses salt and sugar to cure the salmon. Various herbs are used to give flavor to the salmon, typically white pepper and dill, and the salmon is eaten raw after the curing process is finished.  Note: because the salmon is never cooked, keeping preparation surfaces and tools especially clean throughout the process is highly recommended. Use high-quality salmon if possible, acquired from a trustworthy source. Using farm-raised salmon is recommended, due to a lower chance of health issues. Although the chance of parasites is not high to begin with, you can reduce the risk further by freezing the salmon first, then defrosting it. Use a pair of tweezers or a small knife and fork to remove the scales and bones of the fish. Leave the dark skin beneath the scales attached to the rest of the salmon. These cuts allow the spice mixture to soak into the salmon, giving it more flavor and better preservation. Chop up one bunch of dill, or about 8 tbsp (120 mL), and crush 1 tsp (5 mL) white peppercorns. Mix these into 3¼ oz (85 g) sugar and 4 oz (120 g) salt. Experienced gravlax chefs will vary the ratios of these ingredients to suit their tastes, but the large quantities of sugar and salt are important so the salmon is properly cured. Heap the spice mix onto the salmon fillets, turning the salmon to make sure it is exposed to the mixture on all sides. Place the salmon in a glass or stainless steel container, touching the salmon fillets together on the pink flesh side, rather than the dark skin side. Cover completely with plastic wrap, then press the fish down with any heavy object, such as a brick. During this time, the salt and sugar should melt into the salmon, adding a stronger flavor. If you are not comfortable preparing raw food, you may wish to move the fish directly to the refrigerator instead, reducing the risk of bacterial growth. Move the salmon to the refrigerator, keeping the weight on top of it. The longer you keep it there, the stronger the flavor will be, and the drier the fish will get. Try testing it every 24 hours to see if you enjoy the flavor. Once the salmon has achieved the flavor and texture you prefer, take it out of the container. Scrape off all the spices, and discard any liquid that has been created. This common pairing with gravlax can be found at scandinavian food stores. Alternatively, you can make it yourself using the ingredients for the "sauce" listed beneath the gravlax recipe. Mix the mustards, sugar, and vinegar together first, then pour the oil slowly into the mix while stirring. Once it has reached a mayonnaise consistency, stir in the chopped dill and season with white pepper and salt to taste. Rye crackers or rye bread are another common food served together with gravlax.

article:
Because calcium carbonate scaling is white and flakey, it is easy to remove with a pumice stone. You can purchase pumice stones from your local pool maintenance store or online.  Pumice stone is safe to use on hard surfaces such as tile and concrete. It can be used on both concrete and plaster pools. Do not use pumice stone on vinyl or fiberglass pools. Use a nylon brush if your tiles are glass, ceramic or porcelain. A nylon brush will not scratch these tiles. As an alternative, you can use a 3M blue or white nylon scrub pad. Releasers, such as the Ocean Care Calcium Releaser, will soften the calcium for removal. The Ocean Care Calcium Releaser is acid-free, biodegradable, and non-toxic, making it safe to use without having to drain your pool completely. Scrub the tiles until deposits, mildew, and build-up are gone. If using a pumice stone, make sure both the tile and the stone are wet at all times while cleaning. This will prevent any scratching. You may wear latex gloves to protect your hands while cleaning, but it is not necessary.
