Washing - continued After parking the car under a shade, apply water liberally on the tyres. After that, use a good cleaning agent of your choice - I prefer car shampoo - and use a mild brush to brush down the tyre to clean all the mud deposited. If you are really particular, you can even jack up and clean the stones which have got lodged in the grooves. Brush down vigorously and follow it up by again water washing the tyres - use plenty of water and make sure that there is no soapy residue left. When you are done with tyres, start clean your alloys\wheel caps. Dip a rag in the foam and wipe down the alloys\wheel caps throughly and then wash them thoroughly with water. After thoroughly cleaning with water, wipe down the tyres with cotton waste. If you are particular about tyre shine or want to keep the tyres looking like new, you can apply tyre cleaners. You can use alloy wheel cleaners \ break dust repellents or as a lesser effective substitute, you can use good wax on the alloys. Once you are done with tyre and alloys, start hosing down the car with plenty of water. If the water you use is hard water, you can use some softening agents (like ONR in preferred dilution). Use plenty of water to loosen the dirt, but do not use a cloth to drag the dirt - dirt particles may get lodged in teh cloth \ sponge and may introduce micro scars. While hosing the car with water, do not use much pressure - this can make the grit drag over the surface which in turn will results in micro scratches. After this, take some water in one bucket and add a good car shampoo to it. Car shampoos are usually pH controlled, and are based on detergents - not on soaps. Soap based cleaners may contain trace elements which can damage the paint. Use a wash mitt or a microfiber cloth or a good soft cotton cloth to apply the form on the car surface. general purpose Sponges are less preferred since they have cavities which can entrap dirt particles which can streak the surface. Use small motions instead of long sweeping motion and make sure that every time the cloth\mitt picks up dirt, rinse it in the water in the other bucket. This technique of using two buckets - one to dip and wash and other to rise clean the cloth - is called two bucket technique. An alternative is to use a bucket with grit guard. A grit guard is a plastic guard which sits inside the bucket which traps the grit to the bottom of the water. make sure that you rinse the cloth frequently so that the cloth remains dirt free every time you use it on the car to apply foam. Foam the car thoroughly - it is advised to have different cloths to foam the lower side of the car and upper side of the car. Dirt accumulation are more on the lower half usually. When choosing a good car wash liquid \ shampoo, do not choose one which contains trace elements of wax -wax is a sealant and when you wash, you want the paint to open up - not seal close.
