Once you use the brick, you must wax the car using a standard wax- I prefer carnuba based wax myself. Then the car will shine and water will bead until the wax wears off. I normally wax my cars each season. If you would like to read about some more of my personal car care tips- well here they are.
1. Never, ever go through an automatic car wash.
2. Use only cool, low pressure water for wetting and rinsing. When I lived in hard water parts of the country, I plumbed a soft water line in my garage for washing the car. That really helps avoid water spots.
3. Use clean terry cloths for washing and polishing and a clean chasmois (spelling check) for drying. Never leave the car wet- especially in the sun. That is like putting you car's finish under a million little magnifying glasses. Remember what a magnifying glass can do to a bug?
4. I use car wash soap which is good stuff and minimizes spotting and streaking. Maybe it helps the wax last longer too, but I do not know that for sure.
5. Be sure to wipe clean all doors, door openings, undersides of trunk lid and hood.
6. Keep bugs cleaned off the front of the car. The sooner they are cleaned off, the easier they come off. I try to wash my car immediately after a long trip- just like taking good care of a horse.
7. Always clean the wheels- I use a brush to get in between the spokes. Brake dust left unchecked can harm the wheel finish. Seriously dirty wheels can even cause an imbalance.
8. I wipe down the engine with a damp cloth every time I wash the car. A little effort often- saves time over the long run.
9. Clean the windows and wipe them dry with a newspaper. The ink in the paper polishes the glass. But don't do this to the rearview mirrors. The mirror glass is too soft. Treat the mirrors like prescription glasses. I use RainX or wax on the mirrors, side glass and rear glass. Then the water rolls off the glass in the rain and improves visibility. I hate driving a rental car in the rain. The water sheets on the mirrors and side glass and makes it hard to see.
10. A tip that I have not yet tried so I cannot say if it is good or bad: You know how after a your car is a few years old- the wipers leave a shiny zone on the windshield? Well, according to collegue who used to work in Wiper development, he says that cleaning your windshield with Brasso will eliminate this shiny zone and wiper chatter. I have yet to try this- I don't think it can hurt. If someone does try it, let us know how it works out.
