How Professionals Remove Rust...

Although the success of many household cleaning tasks usually depends on choosing the right cleanser, there are some instances where the labor required to remove a stain, or a film is too much.

 

Either the stain might be bound too tightly to the surface, or the area to be cleaned is too large for hand scrubbing. In such cases, you will need an alternate cleaning technique with more power, and that's what makes pressure washing the ideal option.

 

Pressure washing is used to clean parking areas, walls, statues, buildings, homes, and even heavy equipment. One of the reasons why pressure washing is preferred, is because it uses pressure to clean surfaces. In fact, this method can also be used to remove rust, hard water deposits, lime and minerals from different surfaces.

 

If you own a garage, pressure washing can be used to remove oil and grease stains from your driveway or garage. It can also be used to remove graffiti! Therefore, it is an effective method of cleaning different areas in your home.

 

However, it is important to understand that professional companies use different pressure washing methods for hard to clean surfaces. The most common methods are below:

Power Or High Pressure Cleaning

For power washing, internally heated water is discharged at a high pressure, with the aim of removing dirt and rust from the surface being cleaned. In case you need specific cleaning or removal of a specific stain, you need to add certain chemicals or solvents to facilitate the cleaning process.

Soda Blasting

In soda blasting, sodium bicarbonate (baking soda) particles are blasted against a surface using compressed air. It is usually a non-destructive method that can be used in rust removal, stripping paint and varnish, removal of graffiti, removal of oil, soot remediation, cleaning, and maintaining industrial equipment.

 

Normally, soda blasting is used to clean multi-layered surfaces. Soda blasting is preferred when cleaning around food equipment, because it is environmentally safe, it is non-corrosive, and does not normally require a mask, although one should still be worn.

 

Sodium carbonate, on the other hand, will make water more acidic, so it may work better on stains that are harder to remove. However, it can leave a white residue on surfaces if it's not rinsed thoroughly. And also, it's more damaging to skin, so extra protection would have to be worn.

Sandblasting

This method is intended for use in jobs that require abrasion or stripping. Therefore, sandblasting is used to shape, smooth, and clean hard surfaces by forcing solid particles on the surface at high speeds.

 

Although this method applies the same principle as using sandpaper, sandblasting is fast and provides better finishes, especially in corners.

Dry Ice Blasting

This is a form of carbon dioxide cleaning, since it uses dry ice (which is solid carbon dioxide) to clean surfaces. Dry ice is accelerated in a pressurized air stream, and then directed to the surface being cleaned.

Dry ice blasting uses the same principle of cleaning, just like the other pressure cleaning methods. However, dry ice blasting substitutes dry ice as the blasting medium. When dry ice reaches the surface, it turns into a harmless gaseous substance, due to pressure impact.

 

This method leaves no chemical residue, because dry ice sublimates at room temperature. Therefore, this method is safe and can be used around food equipment.

Conclusion

It is important to understand the different pressure washing methods, because it will help you make the right choice when it comes to cleaning surfaces. If you don't know which method is ideal to use when cleaning, seeking professional advice is advisable, to avoid making a mistake. Contact C and J Pressure washing for any questions.

 

Finally, if you don't know how to clean using any of the above methods, hire a professional to do it for you, rather than doing it yourself and ending up doing it wrong.
