Even if a car is not new it can still be treated to that showroom gleam by keeping it washed and polished. Never wash the car in direct sunlight as it is too easy to leave streak marks all over as the water dries unevenly on the bodywork. 

•    Step 1: Rinse car all over with plain water and hose. 
•    Step 2: Use a good quality car pre-wash product and apply with a woolly car wash mitt. Start at the roof and work down, a panel at a time.
•    Step 3: Now the main wash with a car shampoo of choice, change mitt for a sponge and work shampoo into car with circular motions.
•    Step 4: Clean wheels and tyres with a brush then wash out thoroughly using a different sponge.
•    Step 5: Rinse shampoo off both bodywork and wheels with fresh clean water, hose preferable.
•    Step 6: Dry off with a chamois.
•    Step 7: Polish. Add to polish to two pints of water and rub into paintwork only. Buff to finish.
