Q: If you are a medical professional who will be performing an anorectal exam, then your first step should be to explain to your patient what the exam entails. Then, have the patient sign a consent form if they agree to undergo the procedure. You could explain the procedure by saying something like, "For this exam, I will be inserting a gloved finger into your rectum to check for abnormalities. You may experience some pressure and/or discomfort, but the exam only take a minute or two." Before performing any type of physical exam on a patient / person it's important to wash and sanitize your hands because you don't want to transfer any bacteria, viruses or parasites to them. Using warm water with soap is usually adequate, but you may want to use an alcohol-based sanitizing gel also. Dry your hands thoroughly and then put on a new pair of nitrile or latex-free examination gloves. In the medical field, digital rectal exams (DRE) are typically done by your family doctor, gynecologist, proctologist, or nurse practitioner. Proctology is the branch of medicine that deals with problems of the anus, rectum and colon. Giving and receiving a digital rectal exam can be awkward or embarrassing for people, so acting professional and reassuring the patient / person is important. After explaining the procedure in general, ask the patient / person to remove their bottoms, lay of their side (typically left side down), bend their knees and place their hands near their chest this is essentially the fetal position or on their left side with their knees flexed. Keep them covered with a gown or blanket for privacy and warmth. Place a protective pad under their buttocks as well. DRE can be done with the patient / person standing. Women may be examined as part of the pelvic exam therefore they may be laying back with their feet in stirrups. Men are often examined while they are standing up, unless they are feeling nervous and then laying down may be more comfortable. Laying on their side is often more relaxing and provides better access to the anal canal. To feel more comfortable, it may be best to have a DRE carried out by someone of the same gender. Man on man or woman on woman, a request for a nurse to be present is also an option. It may also help ease anxiety and vulnerability to have a friend or family member present during the exam. Position and drape the patient for warmth as well as privacy. As a courtesy and to prevent the patient / person from being too shocked and uncomfortable, make sure the lubricant is warmed up a little before applying some to your index finger. Even room-temperature gel can feel cool and cause the anal canal to contract, which makes the digital exam more challenging. The goal is to have the anal tissue as relaxed as possible, so inserting a finger doesn't become uncomfortable or painful. Sometimes a rectal examination is carried out using a local anesthetic in order to numb the anal area and reduce discomfort. This is particularly true if the examiner has large fingers and the examinee has an especially tight anal sphincter. Electric gel warmers are inexpensive and can be purchased at medical supply stores. Alternatively, most gels and lubricants can be warmed in a microwave for 20-30 seconds. Once your finger and the anus is lubricated with warm gel, part the patient's / person's buttocks and slowly insert your index finger. It's best to ask the patient / person to take a deep breath during the insertion of the finger in order to relax them and prevent them from contracting their anal sphincter. To facilitate the insertion of the finger, slowly rotate or twist your hand at your wrist in a back and forth motion. Right before inserting your finger, quickly assess the anus for any abnormalities, such as hemorrhoids (swollen blood vessels), warts, rashes or fissures (tissue tears). After your finger is fully the rectum, assess the anal tone (strength) by asking the patient / person to bear down and try to squeeze your finger. Once inside the rectum, use your index finger to feel for any abnormalities, such as unusual bumps, hard spots, soft spots or fissures. Rotate your finger clockwise then counterclockwise to feel the entire internal circumference of the rectum. You can also palpate the prostate gland (in males) through the wall of the rectum. Feel anteriorly (towards the front) for the prostate, which has two lobes with a cleft between them. A healthy prostate gland is smooth to the touch and not painful upon probing. If pressing on the prostate gland hurts, it may be a sign of benign growth, infection or cancer. It's normal to feel like urinating when the prostate gland is pressed / probed from the anal canal. Once you're finished with your assessment, slowly remove your index finger and examine the glove for the presence of any blood and/or mucus. Then clean off any lubricant around the anus and remove and dispose of your gloves, and wash your hands. Allow the patient to wipe themselves off in privacy with some soft tissue paper and let them know they can get dressed. To remove your soiled glove, take your index finger of your other hand (which should be clean), place it under the cuff of the soiled glove, then pull down towards your fingers and peel it off. The exam itself shouldn't cause bleeding, so if you see blood on your glove that could be a signs of hemorrhoids or another internal problems. After the procedure, check to see how the patient is feeling, especially if he was nervous before the procedure began. Also, keep in mind that going from a laying to standing position can make some people feel faint, so encourage the patient to do this slowly and observe them for a few minutes.
A: Explain the procedure and make sure consent is provided. Sanitize your hands and wear gloves. Reassure the patient / person and tell them to lay on their side. Apply warm lubricant to your index finger. Insert your finger into the anal canal gently. Feel for any abnormalities. Remove your finger and clean the area when finished.

Q: Look for a specialized whitewall tire cleaner in the automotive section of a department store or hardware store. Regular cleaners like Comet can work well to remove dirt and discoloration on the tires, but they can dry out the tires in the process, leading to early wear. Cleaning products containing alcohol or chlorine bleach should be avoided for the same reason. For the best results, opt for all-natural whitewall tire cleaners (e.g. Simple Green). Use an SOS pad for regular cleaning of whitewall tires. Use a hose to wet the tires. Wet the SOS pad as well. If your chosen tire cleaning product is in spray form, spray it directly onto wet tires. If it is a liquid, mix the product in a bucket with water (as per the directions on the label). Soak your SOS pad in the mixture. Put a generous effort into cleaning your whitewall tires thoroughly. The effectiveness of the cleaning is just as contingent on the duration and intensity of the scrubbing as it is to the products used. If the work is too intense to tackle on your own, enlist the help of a friend or family member. Rinse your tires every few minutes while you wash them to see how clean they are getting. Reapply your cleaning product and continue until you are satisfied with the results after rinsing. After you have scrubbed your tires clean, use the hose to rinse them off thoroughly.
A:
Use a specialized cleaner. Wet the tires and cleaning pad. Apply the cleaning product. Scrub tires thoroughly. Rinse off your tires.
