If Working At Home A Drip Pan Is Obligatory


You likely saw that we mentioned a drip pan and absorbent pads are optional. If youre renting a space to work in for the day, you probably wont need one. The floor will have built-in drains for toxic waste. You wont have this advantage if youre parked on your driveway or street.

Runoff thats contaminated with oil, fuel or coolant is an environmental hazard. You cant allow it to puddle on the street or get into storm drains. This is considered polluting as it can degrade local water quality. In lakes or streams, this toxic waste can affect local wildlife.

Pets and young family members also walk through puddles outside. This is a risk you dont want to take so use a drip pan.

You may want a few different size brushes to help you reach into all the nooks and crannies. If you don’t have a shop vacuum, you can blow the dirt and dust away with a leaf blower. Go over the entire engine with the brushes and vacuum.XResearch source
  • 2Scrub aluminum parts with a metal wire brush. The intake sits at the top of the engine and is usually made from aluminum, which can get stained and pitted. Rub a metal wire brush over the entire intake and any other aluminum parts, like lettering plates, to clean them. Be careful not to rub any hoses or sensors with the metal wire brush.XResearch source
  • Alternatively, you could use a rotating wire wheel to clean aluminum parts.
  • 3Wet the engine bay with a weak stream of warm water. Spray the engine bay with a weak stream of warm water before applying any cleaner to remove loose dirt and grime. Avoid spraying the covered electrical parts. Rinsing the bay first helps the cleaner to spread evenly and reduces spotting. Make sure you don’t use cold water, which could crack the block.XResearch source
  • Products like Simple Green and Purple Power Degreaser work well for detailing engine bays.
  • If the engine bay still looks pretty dirty, spray more diluted degreaser, let it soak for 5 to 10 minutes, then rinse it away.

    • Is it as difficult as it seems?
    • What is the best car engine cleaner to use?
    • What are the safe methods for a clean car engine?

    Analysis of a car engine: Car engine’s today are not the car engines of yesterday. If you look at your car engine you will start to notice a few critical factors that actually make car engine cleaning and detailing safer and easier than ever:

    • Much of the engine is covered in plastic shrouding.
    • Electric connectors are fully protected with sturdy plastic housings and assembled using moisture protecting grease.
    • Electronic ignitions mean the elimination of traditional distributors and carburetors.
    • Alternators remain as the only sensitive area with the appearance of exposed wires, etc.

    The good news is that any modern day car engine is extremely protected from water, dirt, and other harmful elements of car ownership in the real world. The alternator is about the only thing any lay person can identify that would represent some form of risk, and the good news is that alternators represent no risk from direct contact with water.

    What Components Should Be Covered And How

    The Safest Way To Clean Engine Bay

    You cant dismantle every component that shouldnt get wet. Theyll have to be covered with plastic bags or cling film.

    If youre using old bags, check them for holes. A tattered or torn bag will defeat the purpose.

    List Everything You Covered

    Driving around with plastic still floating around your motor can be disastrous. If youre forgetful, make a list of every component you covered. This way, once youre done youll know how many coverings to take out.

    Caps and Dipsticks

    Place a bag over each cap and dipstick. Use your tape to secure each one to prevent it from moving around.


    Disconnect the battery if you havent done so already. Cover it with a large plastic bag as well as you can.

    Electronic Mechanisms

    Electricity and water dont mix. Luckily, modern vehicles are better insulated in this respect, theres less to protect than with older vehicles.

    Use your cling film, tape and plastic bags to cover the following:

    • Spark plugs.
    • Any other exposed electronic mechanism .

    Air Filter

    Cover the air filter, another part that shouldnt get wet.

    Special Precautions for Antique or Heavily Modified Vehicles

    Older cars and modified vehicles may have additional components that need covering. Examples include carburetors, which almost all modern engines are built without, distributors, electrical connections, etc.

    The same applies for turbocharged or supercharged motors. Cover all modified, water-sensitive parts as needed.

    The Simplest & Fastest Way To DEEP CLEAN a Car Engine Bay!

    If you find the thought of cleaning your car’s engine intimidating, you’re not alone. Due to the mechanical parts, electrical components, belts and more under the hood, many people cringe at the notion of a do-it-yourself engine cleaning job. But the process can be surprisingly simple, and you can get the task done in less than an hour with a few basic steps.

    The more you drive your car, the more you’ll find uninvited guests such as dirt, grime, pebbles and accumulations of oily, greasy residue. This can cause your vehicle’s engine to look dingy and dirty, eventually diminishing performance and potentially leading to damage.

    With a clean engine you’ll enjoy more efficient cooling, less wear on cables and pulleys and a better overall life for your vehicle. A schedule of basic maintenance 1-2 times a year can help you spot any leaks, leading to a better overall life for your vehicle.

    Before cleaning a greasy engine bay, be sure to check your county and state laws for public car wash regulations, as well as your car owner’s manual for cleaning & degreasing recommendations. If you’d rather not clean your engine bay at home, you can go to a self-serve car wash. These facilities are required by law to recapture and clean water in a closed system that filters and collects any hazardous substances for safe disposal, before returning the clean water to service.

    Tips For Battling Salt Corrosion In The Engine Bay

    If you’re in an area that’s affected by a lot of salt corrosion, you might want to look into getting your engine bay ceramic-coated. There are ceramic coatings designed for every surface of your vehicle, and your engine bay is no different. Ceramic coatings are very durable, long-lasting, and offer a much thicker layer of protection compared to waxes and sealants. This will prevent salt and grime from sticking to metal pieces and causing future corrosion, leaving your engine bay looking newer for longer!

    Wet Engine Bay Before Applying Cleaning Products

    A preliminary rinse will take off the layers of loose dirt, dust and grime you didnt catch.

    Step 1: if Using a Pressure Washer, Check Setting Is Low

    Double-check that the pressure is at the lowest setting. If not, youll be surprised by a powerful jet of water instead of a mild one.

    Step 2: Rinse the Bay

    Rinse the entire engine bay, avoiding the parts you covered. Try to avoid wetting wires more than you absolutely have to. Remember not to spray water in any one area for too long.
