Our homes undergo spring cleaning each year to prevent dust, dirt, mold and mildew from completely taking over, and the exterior of our houses are no exception. Homeowners swear that their electric pressure washers are like magic wands in this case. However, it takes more knowledge and experience to learn how to use it correctly, as well as to choose the right cleaning agents and tools for the job. Here are some tips and strategies in power washing mold and mildew from your walls for a deep clean from VT Mobile Pressure Washing Houston:
The Right Pressure Washer
These useful machines are measured on how effective they are by their PSI pressure (pounds per square inch) and their GPM (gallons per minute), combined to form Cleaning Units. Cleaning units are the standard measurement of effectiveness- the more, the better. A bonus in choosing the right pressure washer is that it should also be able to dispense cleaning products aside from the water. Adding a little chlorine can keep mold and mildew from coming back, preserving your walls for a longer period. You may also pretreat the walls first with a mixture of liquid bleach, water, and Jomax mildewcide or any similar product. Spray it on, scrub a bit, rinse then let the pressure washer and a multi-purpose siding cleaner do the finishing work and leave a streak-free, spotless wall.

The Right Safety Precautions
Heed these advice to maintain an accident and injury-free power washing:
1. Cover all electrical outlets before starting. Duct tape or use the screw-in covers that come with some outdoor outlets to seal them. Doing this will prevent water and any cleaning agent to seep in and cause an electrical shock, or cause a blackout. You may also check for power lines before using the ladder in hard to reach places. Avoid the electrical meter, the exterior lights, and the electrical cables when using the pressure washer.
2. A pressure washer can be deadly if operated outside what it is intended. Always start off with a wide fan pattern before adjusting to a narrower one. Test and point it away from you or any other people in the vicinity. Wear protective clothing such as long-sleeved shirts, boots, and gloves, plus eye and ear protection. There are colored nozzles that indicate the degree of pressure the washer is currently on- Yellow sprays at an angle of 15 degrees while green sprays at 25 degrees. White nozzles sprays at an angle of 40. Reserve the red indicator nozzle, which sprays at a powerful 0 degrees for particularly stubborn dirt, mud, mold and mildews and remember not to put pressure in one place for too long. Keep it moving, and observe the recommended distance. Be careful not to blast water upwards at sidings, directly into corners, under window edges and doors or into attic vents and dryer vents.
Use the lowest cleaning settings first and switch them up as you go. A good rule is to apply the cleaning chemicals from the ground up first, and then use the pressure washer to clean from the top down.
3. Stand firm when using ladders in high areas. Position the ladder at a safe and proper angle before ascending and operating the washer. Your base should be very stable to prevent the washer’s pressure knocking you off your feet and causing additional damage. Take short breaks when cleaning your walls and stop if you feel tired or uneasy.
