Oil sleeks and grease spots can often cause safety hazards when left on concrete and asphalt roads as they could potentially cause vehicles to slip and veer out of their proper way. In fact, these substances are even dangerous when left on sidewalks and pedestrians as their slippery nature can cause people to slip and injure themselves. Removing oil sleeks and grease spots is not easy as they have the tendency to repel water. Although they are vulnerable to soap, often, it is still not enough to remove them, especially if there is a lot of substance to remove.
In order to remove these slippery substances, whether on the streets, pedestrian, or elsewhere, you need the cleaning power of a hot water pressure washer. The main reason why hot water pressure washers are effective in combating oil and grease is because the high heat and high pressure brought about by these cleaning units can actively help lift the oil or grease from the surface it is adhered to. This high heat also helps to melt and dissolve hardened oil and grease, making it easy for chemical solutions to penetrate and emulsify them so they can be flushed away from the surface.
Pressure washers basically work by pressurizing water and ejecting it out at high velocity. This increase in speed is responsible for their cleaning power. Most pressure washers use cold water and are very effective in removing tough dirt and debris, but are weak when it comes to removing oil and grease. Without the added help of heat, a standard pressure washer will not be able to clean away oil and grease. However, by adding heat to the system, it becomes very effective in removing oil and grease.
Hot water pressure washers generate heated water when the water passes through heating coils. This brings the water to temperature. The truth is hot water alone can help to melt and dissolve oil and grease. Adding high pressure to it only makes it more effective.
There are times also that you need to resort into using specially formulated chemicals to help with the cleaning task. When cleaning oil and grease, there is nothing better than having degreasing solutions to help lift, dissolve, and emulsify them. This not only helps make the cleaning task of removing oil and grease easier, but also faster.
It is important to remember however that using pressure washers is dangerous, especially when there is heat involved. This is why it is very important to always practice pressure washer safety whenever operating the unit to avoid unnecessary mishaps.
