Anyone working with gel, shellac, or UV polish will quickly encounter various liquids: cleaner, remover, nail prep, primer, nail polish remover, and disinfectant. At first glance, many of them look similar—but their tasks differ significantly.

While a cleaner is primarily used for cleaning and, depending on the product, for removing the sticky layer, a remover is intended to dissolve suitable materials from the nail. Nail prep and primer, on the other hand, are used during the preparation of the modeling.

Knowing which liquid to use and when can help avoid common application errors.

Cleaner, remover, nail prep & primer – what is what?

Important: The exact usage always depends on the respective product and nail system.

What is nail cleaner?

Nail cleaner is a cleaning liquid for nail modeling. Depending on the composition and product, cleaner is used, for example, to clean the nail surface and remove the sticky layer after curing a gel. Cleaner is not a remover and is not intended to dissolve a cured gel modeling or UV polish layer.

Why is cleaner needed for gel nails?

Cleaner can be used at different stages during gel modeling. A particularly well-known case is removing the sticky layer, also known as the dispersion layer.

Depending on the system used, cleaner may also be intended for cleaning the nail surface or tools.

Note: Do not automatically use cleaner after every cured gel layer. The sticky layer may be relevant for bonding with the following layer. Therefore, the instructions for the system used are always the deciding factor.

What is the sticky layer?

The sticky layer—also called the dispersion layer or inhibition layer—is a tacky layer that remains on the surface of many UV/LED-curing nail products after curing. It does not automatically mean that the gel is not cured. Depending on the work step, it remains in place or is removed with a suitable cleaner.

Why is gel sticky after curing?

The sticky surface can be the normal dispersion layer. It forms on the surface of many light-cured systems. Therefore, a sticky gel should not be automatically cured again or filed off.

What is crucial is whether the specific product forms a sticky layer and what the next step is.

When must the sticky layer be removed?

That depends on the work step.

If you are working directly with another suitable gel layer, the sticky layer is often not removed. Before certain filing work or after a sealing gel that leaves a sticky layer, cleaning it off may be intended.

With no-wipe or finish gels without a sticky layer, this step is completely unnecessary.

What is nail remover?

Remover is a liquid for dissolving suitable nail products. Depending on the remover and the nail system used, this includes, for example, shellac, UV polish, soak-off products, or certain rubber base systems. A classic hard gel modeling, however, cannot automatically be dissolved with remover.

Cleaner or remover – what is the difference?

Cleaner cleans – remover dissolves. Cleaner is used during nail modeling for purposes such as cleaning and, depending on the product, removing the sticky layer. Remover, on the other hand, is used to dissolve suitable UV polish, shellac, or soak-off products from the nail. The two liquids perform different tasks and are not interchangeable.

Can you remove gel nails with remover?

Not every product labeled as "gel" can be dissolved with remover. Classic modeling gels are usually reduced or filed off mechanically. Soak-off products, however, can be dissolved with a suitable remover, depending on the system.

If you want to remove UV polish from an existing gel or acrylic modeling, it is best to file the polish off.

Whether a nail product can be removed with remover does not depend solely on whether it cures under UV/LED light. The deciding factor is whether the specific material is intended to be soak-off or dissolvable by remover.

How do you remove shellac or UV polish?

With a suitable UV polish system, removal typically works using remover and wraps.

For the emmi®NAIL shellac/UV polish remover, the shiny surface of the UV polish is first carefully roughened. Then, a remover wrap is soaked and placed around the nail. For the 500 ml remover, we recommend an exposure time of about 8 minutes in this application and advise against leaving it on for longer than 10 minutes.

The separate emmi®NAIL remover wraps are also specifically intended for removing shellac or UV polish.

Most importantly: Do not forcibly tear or peel the dissolved coating off the natural nail.

Remover or acetone – what is the difference?

Is remover the same as acetone? No. Remover refers to a product for dissolving suitable nail coatings. Acetone is a solvent that can be a component of a remover. There are both acetone-containing and acetone-free removers.

Is nail polish remover the same as nail remover?

Classic nail polish dries in the air. Shellac or UV polish, however, is cured under UV/LED light. Conventional nail polish remover is not sufficient to remove UV polish. Therefore, always check the intended purpose of the specific product.

Can you use nail polish remover instead of cleaner?

Cleaner and nail polish remover are formulated for different tasks. Nail polish remover is intended to dissolve polish components. Cleaner is intended for specific cleaning steps within a nail modeling process.

Additional ingredients in a nail polish remover may also be undesirable if further modeling layers are to follow.

The safest principle is therefore:

Cleaner, remover, and nail polish remover should not be swapped simply because they look similar. The composition, intended use, and the requirements of the nail system used are the deciding factors.

Can you use isopropanol instead of cleaner?

Isopropanol or 2-propanol is an alcohol that can be a component of various cleaning products. Whether it is suitable in a certain concentration for a specific step in a nail modeling process, however, depends on the system and product used.

For reproducible salon results, a product intended for the respective work step is the safer choice.

What is nail prep or dehydrator?

Nail prep or dehydrator is used before the actual modeling.

Its task is to prepare the nail plate for the following modeling and to reduce disturbing moisture or oils. In this, nail prep already differs from cleaner in its function.

In short:

Nail prep = preparation of the natural nail
Cleaner = cleaning during or after specific modeling steps
Remover = dissolving suitable coatings

What is primer?

It is used as an adhesion promoter between the natural nail and the following modeling system. Depending on the condition of the nails and the system used, different primers are suitable. Read more in the primer guide.

What comes first: nail prep, primer, or base gel?

As a general principle, a modeling—provided the specific system requires these products—can be structured as follows:

Prepare natural nail → Nail prep/dehydrator → Primer → Base/Adhesion gel → Modeling

However: Not every nail system requires all these steps. Therefore, the specific processing instructions of the system used take priority.

Which liquid do I need for shellac or UV polish?

For a UV polish system, several liquids can perform different tasks:

Preparation: suitable prep/cleaning product according to the system
Processing: if applicable, cleaner, if required by the system
Removal: suitable UV polish remover
Aftercare: for example, nail oil

Which liquid is needed for gel nails?

For a classic gel modeling, nail prep/dehydrator, primer, and cleaner can be used depending on the system.

Remover, however, is not automatically part of removing a classic gel modeling. Here, it is crucial whether the material used is explicitly soak-off or dissolvable by remover.

This results in a simple guide:

The 5 most common confusions

Cleaner ≠ remover: Cleaner cleans, remover dissolves suitable coatings.

Remover ≠ automatically acetone: There are acetone-containing and acetone-free removers.

Cleaner ≠ nail prep: Nail prep is specifically for the preparation of the natural nail.

Primer ≠ base gel: Primer is an adhesion promoter; base gel forms a product layer.

UV polish ≠ classic nail polish: UV polish is cured under UV/LED light and requires a removal system designed for it.

Cleaner, remover, nail prep, and primer fulfill different tasks in nail design. Cleaner is used for cleaning and, depending on the product, for removing the sticky layer. Remover is used to dissolve suitable UV polish, shellac, and soak-off products. Nail prep or dehydrator prepares the natural nail, while primer can be used as an adhesion promoter for the subsequent modeling. Which products are actually needed depends on the nail system used.
