Comparison: Zep 505 vs. Zep Purple

Formulation Differences

One of the primary differences between the Zep 505 and the Zep Purple lies in their formulations. The Zep 505 is a heavy-duty cleaner and degreaser designed for a wide range of applications, while the Zep Purple is a shop-grade solvent specifically formulated for industrial and commercial use.

Intended Applications

While both products are versatile, the Zep 505 is more commonly used for residential and light commercial cleaning tasks, such as cleaning grills, tools, and hard surfaces. On the other hand, the Zep Purple is better suited for heavy-duty industrial applications, including cleaning machinery, engine parts, and shop floors.

Ease of Use

Both degreasers are relatively easy to use, but the Zep Purple may require slightly more caution due to its solvent-based formula. Proper ventilation and safety precautions are recommended when using the Zep Purple in enclosed spaces or for extended periods.

Scent and Odor

The Zep 505 has a citrus scent, which some users find more pleasant than the stronger odor associated with the Zep Purple. However, the scent preference is subjective, and both products may require proper ventilation during use.

Pricing and Value

In terms of pricing, the Zep 505 and Zep Purple are generally comparable, with the Zep Purple being slightly more expensive due to its industrial-grade formulation. However, both products offer good value for their cleaning power and versatility, making them cost-effective solutions for their respective applications.

Choosing the Right Degreaser

Assessing Your Cleaning Needs

When deciding between the Zep 505 and the Zep Purple, it’s essential to assess your specific cleaning needs. If you primarily need a degreaser for residential or light commercial use, such as cleaning grills, tools, or hard surfaces around the house, the Zep 505 may be the better choice.

However, if you’re tackling heavy-duty industrial or commercial cleaning tasks, such as degreasing machinery, engine parts, or shop floors, the Zep Purple’s shop-grade solvent formula may be more suitable.

Surface Compatibility

Both degreasers can be used on a wide range of surfaces, but it’s always a good idea to check the product labels for specific surface compatibility. Some surfaces may be more susceptible to damage or discoloration from certain chemicals, so taking the time to ensure compatibility can help prevent any unwanted issues.

Ventilation and Safety Considerations

When using either the Zep 505 or the Zep Purple, proper ventilation is crucial. Both products can release strong odors and fumes, so ensuring adequate airflow and following safety guidelines is essential for a safe and comfortable cleaning experience.


While both degreasers offer good value for their cleaning power, it’s important to consider the cost-effectiveness of each product based on your specific needs. If you only require a degreaser for occasional use, the Zep 505 may be the more economical choice. However, for frequent industrial or commercial applications, the Zep Purple’s concentrated formula may prove more cost-effective in the long run.

Tips for Effective Degreasing

Proper Preparation

Before using either degreaser, it’s essential to properly prepare the surface. This may involve removing any loose debris or wiping down the area with a dry cloth to ensure the degreaser can penetrate and work effectively.

Application Techniques

Applying the degreaser correctly is key to achieving optimal results. For the Zep 505, spraying or pouring the solution onto the surface and allowing it to dwell for a few minutes is recommended. With the Zep Purple, following the manufacturer’s instructions for proper application is crucial, as it may require dilution or specific application methods depending on the task.

Dwell Time and Agitation

Both degreasers work best when given adequate time to penetrate and break down the grease and grime. Allowing the solution to dwell on the surface for the recommended time can significantly improve its effectiveness. Additionally, agitating the solution with a brush or scrub pad can help lift and remove stubborn stains and buildup.

Rinsing and Drying

After the degreaser has had sufficient time to work, thoroughly rinsing the surface is essential. Failure to properly rinse can leave behind residue or streaks, which can be unsightly and potentially attract more grime in the future. Once rinsed, drying the surface with a clean cloth or allowing it to air dry can help restore its original shine and appearance.


Can the Zep 505 be used on painted surfaces?

 While the Zep 505 is suitable for many surfaces, it’s always best to test it on a small, inconspicuous area before using it on painted surfaces. Some paints may be more susceptible to discoloration or damage from the degreaser’s formula.

Is the Zep Purple safe to use on aluminum surfaces? 

Yes, the Zep Purple is generally safe for use on aluminum surfaces. However, as with any chemical product, it’s recommended to follow the manufacturer’s instructions and test on a small area first to ensure compatibility.

How long should I let the degreasers dwell before rinsing? 

The recommended dwell time may vary depending on the degreaser and the level of grime or buildup. For the Zep 505, a few minutes is typically sufficient, while the Zep Purple may require a longer dwell time for tougher stains. Always consult the product label for specific instructions.

Can the Zep 505 and Zep Purple be diluted with water? 

The Zep 505 is typically used as-is without dilution for most applications. However, the Zep Purple may require dilution depending on the specific task and the manufacturer’s recommendations. Check the product label for dilution instructions.

Are there any safety precautions to consider when using these degreasers? 

Yes, both degreasers should be used with proper safety precautions. Wear gloves and eye protection, and ensure adequate ventilation when using either product. Avoid ingestion or prolonged skin contact, and follow the manufacturer’s safety guidelines carefully.


Summary of Zep 505 and Zep Purple

The Zep 505 Fast Cleaner and Degreaser and the Zep Industrial Purple Cleaner and Degreaser are both powerful degreasers that cater to different cleaning needs.

Final Thoughts on Choosing the Right Degreaser

When it comes to choosing the right degreaser, it’s essential to consider your specific cleaning requirements, surface compatibility, ventilation needs, and cost-effectiveness. By carefully evaluating these factors and following proper application and safety guidelines, you can effectively remove stubborn grease, grime, and stains, leaving surfaces clean and restored to their original condition.
