Problem: Article: This is the most important characteristic as you want a box that can be used as a dog bed that has a high level of sturdiness. You'll also need the box to be large enough to accommodate the size of your dog. If your dog has a tendency to sprawl or move around in its sleep, you may want to choose a box that's on the larger side. If you don't have any suitable boxes at home but still want to make a box bed, you can purchase a box relatively cheaply from a shipping store, the post office, or in some cases, an office supply store. Stress and strain will be put on your box by the simple act of your dog getting into and out of its bed. Over time, this can cause your box to break down or become less structurally sound. To prevent this, apply a durable tape along the edges and sides of the box to reinforce it.  Duct tape works very well for the purposes of reinforcing your dog bed as it is very durable. However, you can also use packing tape or other kinds of tape, though these may not hold up as well to wear and tear. You might also want to tape the flaps at the bottom of your box where the box folds together. This can help strengthen the shape of the box and hold it's shape. Take a pair of scissors or a utility knife and cut a downward pointing U-shaped opening in the box for your dog. For some boxes or dogs, this may only involve you cutting off the top flaps of the box. In other cases, you may have to trim down the sides of the box to make it easier for your dog to enter and exit. You might also want to cut a semi-circular "main entrance" for your dog bed. Take your utility knife and cut a semi-circle in the front of your box. This lowered lip of the box will be easier for your dog to enter, making it the default entrance for your pet. Although this is not necessary, padding can provide comfort and warmth to  your pet. For example, if you're making a bed for an outdoor dog, wood chips can help fight insect infestations while insulating the animal from the cold. Indoor pets may have a special blanket or pillow that they often use that can be put in the box bed for additional comfort. You might also use some leftover padding, rags, old clothing, and more to make your box bed more comfortable for your dog.
Summary: Collect a suitable cardboard box. Reinforce your box. Cut an opening for your dog. Pad your box for comfort.

Problem: Article: Be careful not to bend or dent either slide in the process. Be gentle! If using a cleaning rod, be careful not to jam the rod into the bottom of the slide. If you are rough, you risk denting the crook at the end of the slide.   However, this stage of the cleaning should really be handled by a trained instrument technician, as any sort of scratch or dent in the valve will adversely affect the playability of the horn. Special attention should be given to the rotary valve, water key (or spit valve), and the outer and inner slides.   Most of the oil should be applied by dripping it in through the pipe where the bell section and playing slide meet, though a few drops may be applied to the rotary valve directly.
Summary: Disassemble the trombone by unscrewing the bell portion from the slide and removing the mouthpiece. Remove the outer slide and wipe off any excess grease, oil or moisture from the inner slides with a soft rag. Use a cleaning rod or a “snake” (a flexible rubber coated metal wire with a small brush on both ends), clean out any excess grease, oil or moisture from the insides of the outer and inner slides. Remove the main tuning slide from the bell portion and clean the inside with  a “snake”. Do the same for F attachment tuning slide if your trombone has the F attachment. If absolutely necessary, disassemble the rotary valve for the F attachment, rinse off each piece and wipe off excess oil or grease. Rinse all trombone components with warm water (NOT HOT, see warnings) in a shower or bath. Dry off all components with a soft rag, making sure that no large pockets of water remain in any of the tubing or in the rotary valve. Apply necessary grease to the tuning slides and attach them to the bell portion of the instrument. Reassemble the rotary valve and apply necessary oils. Apply necessary slide grease or oils to the inner slide. Wipe down the entire outside of the trombone using a soft rag.

Problem: Article: Like any surface, it's easiest to wipe up spills as you go. If you wait to wipe up the spill, it can dry on the surface, making it harder to clean. Since Corian countertops are nonporous, the spill won't soak in, making it a breeze to just wipe it up with a clean, damp cloth. Always dry the surface immediately after cleaning. If you don't dry the surface, film will build up over time. If the spill has dried, you can use warm, soapy water to clean it up. Put a bit of dish soap on a rag, then add warm water to make it sudsy. Wipe it over the spill or residue to clean it up, then rinse it with clean warm water. If regular soap and water don't remove the stain, you can use an ammonia-based cleaner. Spray or rub the cleaner in, then wipe it up. Make sure to rinse it with clean water, and don't forget to dry it so you don't leave streaks.  Don't use window cleaners on this type of counter, as these can leave a waxy buildup. Before using any cleaner, read the directions on the bottle. Always test the cleaner first on an out-of-way corner, so you can rest assured it won't create a different problem. Although glass cleaner does have ammonia in it, you should skip it for this purpose. It can leave a film on the countertop. Pick a household cleaner instead. If you don't have an ammonia-based cleaner, you can use another non-abrasive cleaner. It must be non-abrasive because Corian countertops are easily scratched. Spray the cleaner on the counter, and use a clean, wet rag to rub the cleaner in.  You can leave the cleaner on for a minute or two to help remove the stain. Rinse and dry the countertop when you're done. Make sure not to mix different types of cleaners, as that can create toxic fumes.
Summary:
Wipe up spills when they happen. Use warm water and a dishcloth or sponge. Try an ammonia-based cleaner. Pick another non-abrasive cleaner.
