If a clean car is what you're after, look no further than this to-do list from Home and Garden Television. Clean up spills quickly, before they have a chance to soak in and set.
When vacuum cleaning, use the duster-brush attachment to get in all the nooks and crannies of the dashboard, center console and door panels. If you don't have an attachment, use a paintbrush to dislodge the dust.
Use the crevice tool to reach between seats and the console to dislodge food crumbs and other hidden goodies. Remember to move the seats to their extreme front and back positions.
Don't forget to vacuum the seams on seats, where dirt accumulates and breaks down the material.
For upholstery, use a mild solution (a couple drops per gallon) of dishwashing detergent and water to clean seats. Dip a clean towel into the solution and rub gently. For leather upholstery, a leather cleaner is recommended, although the homemade cleaner can be used. After cleaning leather, rub in a conditioner. Use the treatment every six months.
If you have tinted windows, it's better to use an alcohol-based cleaner than an ammonia-based glass cleaner because the ammonia can break down the tint.
A good way to get streak-free windows is to use a micro-fiber towel.
Don't forget to clean the rearview mirrors and side windows.
