Tips to Wash a Car

Dish soap should not be used. Most people usually think that it is an acceptable cleaning agent for cars but it’s not. Soaps made specifically for vehicles can buy from auto stores.

A bucket can be used to mix soap with water for washing with a large sponge or hand. The sponge should be rinsed often to avoid the dirt sticking again to the car’s finish.

The car should be washed in a shady area so that the car itself is cool so that the sun would not dry it faster which could leave spots.

Car washing should be started with the wheels, one at a time. One wheel can be hosed down and then spray cleaner can be used on the wheel and rim. A brush scrub can be used down on all the dirt and mud. It would have to be rinsed and then moved on to the next wheel. One would be surprised how nice they will look.

A trigger nozzle can be used on the end of the hose. It will conserve the water and will give a nice and balanced spray.

The car has to be hosed down properly from top to bottom.

Using the sponge or hand, the roof has to be scrubbed in straight lines going from the innermost part and out to the edges. It would be not suitable to do it in circular motion. The hood would also have to be rinsed.

The sides should be washed next in the same manner, by doing straight strokes from top to bottom. The sponge or hand would to be frequently rinsed.

The hood and the trunk have to rinse next after the sides.

Special attention should be given to the fenders and bumpers especially at the front where bugs breed. Extra elbow grease would be probably needed here.
After finishing the surface areas, the undercarriage has to sprayed for removing the dirt and mud buildup.

After completely rinsing the car, a clean and soft cloth is needed to dry it. It should be rubbed lightly over the surface of the car to smooth out the water droplets. The water should not be tried to rub out. More than one cloth might be needed, this would usually depend on its size and the size of the vehicle.
For waxing, the product’s directions have to be followed. Wax will only be used after the car is completely dried. A car can be waxed up to 3 or 4 times per year.

For the car’s interior, there is no vacuum that would work better than one at the do-it-your-self car wash. Even if one does not have access to it, all the removable rugs and mats can be taken out and cleaned. The mats and rugs outside the car can be vacuumed and then the remaining can be cleaned. A good auto store can be checked for suitable cleansers for washing the dash and interior. One wants to find something that works best on the specific interior. The labels have to read and instructions have to be followed exactly. The better one cares for his car, the better one will feel while driving it. Addition to this, the resale value of the car will also be extremely higher attention is given to its cleaning.

 

When and How to Recharge a Car Battery

As a battery starts to age with the passage of time, its charge becomes weak causing slow engine cranking. A battery might need an occasion jump for starting it, especially when the cars are used for short runs or cold weather. A weak battery can be simply replaced but with a inexpensive recharger. One can nurse it along for weeks months or even years.

If the dashboard warning light shows on then there is a charging system fault. It has to be repaired immediately as recharging will not make it work. If the battery is refillable, the caps should be removed and a damp rag should be laid over the opening while recharging. If it is sealed having a charge-indicator window in the top, only the charger should be used if the indicator is green or dark. If the indicator is clear or yellowish then the battery should be replaced.

A trickle charger should be used to recharge a battery. It is a fairly inexpensive device which is designed to charge a battery at a slow rate. The trickle charger has an electric outlet cord and two wires with alligator clips. One has a red jacket and the other has a black or green jacket. The ignition of the car should be turned off. This has to be made sure first as it is the first important step. The red clip has to be connected to the battery’s positive terminal marked with POS or + and the other has to be connected to the negative terminal marked with Neg or -.

One has to be very careful not to let the metal clips touch each other or any other metal. In such case, they may spark causing an explosion of the hydrogen gas emitted by the battery. That can be dangerous. When the charger is connected to the battery, the charger should be plugged into the electric outlet and turned on. The charger should be run for a few hours or overnight. The charger should be left running until its meter gives a reading of less than 1 ampere. After that, the charger should be unplugged battery should be disconnected.

After recharging, the battery should be checked with hydrometer if it has removable caps. It is an inexpensive device with a float that indicates electric energies in the fluid. If the battery is sealed, it should be tested by starting the engine. After recharging, if the battery still fails to start the engine, a try should be given to jump start the engine. If the engine can be jump started and the charging system light or ammeter indicates normal operation, then it means that the battery is bad replacing it.

 

Tips to Tuning the Car

# The fuel filter has to be replaced. If there is a fuel-injection system then its not necessary to do regular cleaning the injectors are blocked.

# The spark plugs have to be changed. If they are platinum made then the car can run for 30,000 more miles. The wires of the spark plug also have to be examined and can be replaced if required. A new set consisting of high-quality wires is worth the cost. They can be permanently attached to the distributor cap so it will also have to be changed.

# The rotor and distributor cap also has to be replaced. They can be only changed if they are present in the car because some new models with distributor less ignition don’t have it.

# The condenser and points have to be changed. In case of old car roughly 1978 model or older, then it does not have feature of electronic ignition. The points would have to be preferably changed or at least they can be adjusted after every six months or so. If they are changed then the ignition timing can be also checked.

# The ignition timing has to be checked and adjusted if needed. It is rare for a car that has an electronic ignition like post 1980 models and some cars don’t have this at all.

# The valves have to be adjusted as needed. It is not required in case the car has hydraulic valves. It must be made sure that the valve-cover gasket is also replaced as well, especially if oil is seen on top of the engine.

# The fan belt also has to be checked. They would have to be replaced if they are worn out.

# The fluids under the hood have to be checked and they must be refilled as necessary. The engine oil and oil filter would have to be changed if the car has crossed over 3,000 miles since the last oil change.

# The air filter has to be replaced; it should be changed between major car services or after every 15,000 miles also.

# The clutch has to be adjusted if there is a manual transmission. Even though some cars are now sporting self-adjusting clutches.

# The battery has to be serviced; distilled water can also be added if required. The cable ends and terminals are also needed to be cleaned.

# The PCV (positive crankcase ventilation) valve has to be replaced. This can make the car run roughly or also get stalled if it gets blocked. It is not expensive and it’s easy to replace.

Types of Pressure Car Washers

Pressure cleaning machines are classified in many ways. Based on the temperature of their output, they can be either a cold water pressure washer, hot water pressure washer, or steam pressure washer. Similarly, based on the nature of the cleaning job, they are classified into commercial pressure washing machines and industrial pressure cleaning machines. Industrial systems offer higher pressure levels and flow rates for more demanding applications. The power method is yet another dividing factor for pressure cleaners. Today’s systems can be powered by gasoline, propane, diesel, or electricity.

It is not easy to select the best pressure washing machine. Each system is suitable for different applications. The following are a few tips about the specifications that could help select the best machines for various kinds of cleaning jobs.

There are three key specifications defining the power of a pressure cleaning machine: output pressure, output temperature, and flow rate.

Output Pressure

Output pressure level is the force at which water exits the machine. It is expressed in pounds per square inches (psi). Pressure level is perhaps the most important specification as it determines the overall power of the machine. The pressure level varies from model to model, normally between 500 psi and 8000 psi.

Higher pressure levels are suitable for demanding applications, like degreasing or cleaning of heavy machinery, while lighter commercial applications do not need such high levels. Pressure washing machines used for auto detailing also do not need very high pressure levels. The output pressure of such machines should be 1500 psi or less.

Output Temperature

One can classify pressure washing machines into three types based on the output temperature: cold water, hot water, and steam.

Cold water machines eject water at room temperature, that is, without heating the water. Cold water output is ideal for cleaning soft surfaces, namely surfaces that cannot withstand high temperatures, and lighter applications that do not require the additional power afforded by heat. Cold water is not effective for degreasing applications without the addition of a degreasing chemical or green degreaser.

Hot water machines can provide an output temperature of 210•°F. Hot water output has improved cleaning efficiency for difficult cleaning tasks, due to the increase in temperature. However, steam output offers the greatest cleaning power. High steam temperatures up to 330•°F enable the dissolving and rapid removal of the most stubborn residues and grease. Most industrial pressure washer machines utilize steam output.

The best systems on the market today provide all three types of outputs in a single machine. Pressure washing machines that provide all three outputs are called tri-mode machines.

Flow Rate

Flow rate indicates the amount of water that flows through the nozzle in a certain timeframe. It is expressed in gallons per minute (GPM). Flow rate varies from model to model. Flow rates as low as 0.5 GPM are ideal for mobile car wash and auto detailing and applications where drainage is limited, while higher flow rate of 8 GPM are ideal for heavy industrial degreasing applications. Higher flow rates do increase cleaning power, since larger amounts of water are being exerted onto a surface.

 

Tips to Inflating Car Tires

Things Needed
– A garage or gas station that has a facility of Pressurized Air
– A Tire Pressure gauge

# First, one has to go to a garage or gas station that has a facility of pressurized air with a gauge.

#The car should be parked in such a way that one can reach all the four tires with the air hose.

# The air-pressure specifications of the car’s tires have to be found. There is a sticker located on the door jamb of driver’s side, trunk or in the glove box.

# The plastic cap on the air valve would have to be unscrewed. It should be put in the pocket so it does not get lost.

# The air pressure must be checked with the help of either a personal tire-pressure gauge or the one belonging to the gas station air pump. The gauge should be pressed against the valve and held down tightly. If a hissing noise is heard, then it means the air is leaking. It should be pressed down harder.

# Air should be added as necessary. The air pump hose should be pressed on the valve while squeezing the lever present at the end of the hose.

# The air pressure should be checked with the gauge. The air pump hose can also be used for checking.

# The tires must be deflated if they are accidentally overfilled. The small needle in the center of the valve should be pressed down to let the air out. There is a small knob on many tire-pressure gauges for this purpose, although a fingernail or a pen can also do the trick.

Tips and Warnings
– If the tire needs air every time while checking, a tire shop can be asked to inspect for any slow leaks.
– A good-quality tire-pressure gauge should always be kept in the car’s glove box. The cost of a good electronic one costs nearly about $30.
– The spare tire should not be forgotten to check and adding air in it as necessary.
– The tire’s sidewall should not be considered for air-pressure specifications. This is because it only lists the maximum pressure of the tire.
– A tire-pressure gauge should always be used for getting the right air pressure. One cannot afford to exceed or under inflate the tires.
