Identifying polypropylene (PP) plastic involves a few approaches. First, check for recycling symbols; PP is labeled with a number "5" inside the recycling triangle. Secondly, polypropylene has a high melting point compared to other plastics, so a heat test can be indicative; when heated, PP melts and drips but does not emit pungent odors unlike plastics like PVC. It’s somewhat flexible and has a high resistance to chemicals, which can be observed through resistance tests with acids and bases. Additionally, polypropylene floats in water, distinguishing it from many other plastics. For certainty, spectroscopy analysis in a lab can definitively identify PP, but this is not typically accessible for everyday purposes. These methods combined can provide a strong indication of whether a plastic is polypropylene.

For your Hyundai ix35, it's recommended to use SAE 5W-30 or 5W-40 engine oil, which are commonly suggested by Hyundai for most of their vehicles. These grades of oil strike a good balance between performance in cold weather and viscosity at higher temperatures. The 5W-30 grade provides better fuel efficiency and is a bit lighter, making it suitable for daily driving. On the other hand, 5W-40 offers a slightly thicker viscosity at operating temperature, which can provide better protection against wear. It's also important to consider the specific model year and mileage of your ix35, as these factors might influence the best choice. Regular oil changes are crucial for maintaining engine health, so consult your owner’s manual for specific intervals and recommendations. If you drive under severe conditions (extreme temperatures, dusty environments), opt for synthetic oils, which offer superior protection compared to conventional or semi-synthetic oils.

Removing white emulsion paint from carpet requires prompt and careful handling to avoid staining. First, blot up as much paint as possible with a clean, dry cloth, taking care not to spread the paint further. Next, mix a solution of one teaspoon of mild dish detergent with two cups of warm water. Using a clean cloth, apply the solution to the paint stain and blot gently. Do not rub, as this can push the paint deeper into the carpet fibers. Rinse the area by dabbing it with a cloth soaked in clean water, then blot dry with a clean towel. If the stain persists, a specialized carpet cleaner or rubbing alcohol can be dabbed onto the stain, followed by blotting. Always test a small, inconspicuous area first to ensure the cleaner does not damage or discolor the carpet. Repeat these steps until the paint is removed. It's essential to act quickly and be patient, as it may take several attempts to fully remove the paint.
