In one sentence, describe what the following article is about: Birkenstocks are made to last. A clean sole is crucial for retaining a pair of Birkenstocks for many years. This part of the shoe becomes the smelliest the quickest. Each pair of Birkenstocks use the same type of sole, so you can clean them the same way. The easiest way to discolor the footbed of your Birkenstocks is with dirt and grass. Wash the footbed every three weeks with a damp cloth. Let them dry overnight. If you get them muddy, treat them that night with a damp cloth. Don't over saturate the footbed. You can create a great cleaner for the sole's of your Birkenstocks by using baking soda and water. Combine two tablespoons of water with one tablespoon of baking soda. The aftermath should be a paste consistency.  Add more baking soda if it is too watery.  Gently scrub the paste onto the footbed using an old toothbrush. Scrub in a circular motion and wash off with a damp washcloth. Allow your shoes to dry before attempting to clean them further. Always avoid direct sunlight for drying purposes.
Summary: Learn to clean the footbed. Treat the soles regularly. Clean them with a home remedy.

In one sentence, describe what the following article is about: If you suspect that your cat has gone blind or is losing her sight, schedule an appointment with your cat's veterinarian right away. Some types of blindness are reversible if they are treated right away. For example, if your cat is suffering from blindness caused by hypertension, a daily medication may restore her sight and prevent further health problems as well. Make sure that your cat gets regular check-ups with a veterinarian even if she seems healthy. Early diagnosis and treatment of a problem can prevent your cat from going blind. Sometimes a cat will go blind over a period of days, weeks, or months. After the cat has become mostly or totally blind, you may begin to notice some strange behavior. Observe your cat to determine if she might be blind. Some of the behaviors that blind cats display include:  Seeming confused about her surroundings Bumping into furniture and other objects Missing jumps or landings that she used to manage with ease Seeming reluctant to move around or venture outdoors Rubbing or squinting her eyes If your cat's behavior has you suspicious that she might have gone blind, inspect her eyes to see if they look different than usual. Even if your cat is not showing signs of blindness, you should inspect your cat's eyes regularly to check for early symptoms of blindness. Some common symptoms of blindness in cats include:  Eyes don't respond to light, pupils are dilated Eyes look cloudy, inflamed, or discolored
Summary: Schedule an appointment with your cat's veterinarian. Look for signs that your cat has gone blind. Inspect your cat's eyes to check for symptoms of blindness.

In one sentence, describe what the following article is about: 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.
