How to Sanitise Nails Before Gel Polish Application

Proper sanitation before gel polish isn't just about product performance — it's also a professional hygiene and health standard. Here's how to sanitise nails correctly before every gel polish application, and why each step matters.

Why Sanitation Matters for Gel Polish

Sanitation before gel polish serves two distinct purposes. First, it's a hygiene standard — preventing the transfer of bacteria, fungi or pathogens between clients in a professional setting. Second, it directly affects gel polish adhesion — any oil, residue, skincare product or moisture on the nail plate will prevent the base coat from bonding correctly, leading to early lifting and reduced wear time.

These two purposes require slightly different products and steps, both of which should be completed before every gel application.

Hygiene Sanitation: The Client's Hands

At the start of every professional nail appointment:

1. Ask the client to wash their hands — warm water and soap removes surface bacteria and any residual skincare products. This should happen before the client sits at your table.
2. Apply hand sanitiser — a professional antibacterial hand sanitiser applied to both the client's hands and your own before touching their nails.
3. Check nail health — inspect the nail plate and surrounding skin for any signs of infection, inflammation, wounds or contraindications before proceeding with any service.

Product Sanitation: Preparing the Nail Plate

After hygiene sanitation, the nail plate preparation for gel polish involves:

1. Remove existing product — fully remove any previous gel, polish or product. Wipe away all acetone or remover residue.
2. Buff and file — shape the nail and lightly buff the surface to remove the shine, creating mechanical adhesion for the base coat.
3. Remove dust — wipe each nail with a lint-free wipe dampened with professional nail surface cleanser. This removes nail dust and any surface oils.
4. Apply pH Bond / dehydrator — the Gelish pH Bond removes residual surface moisture and adjusts the nail plate pH for maximum base coat adhesion. Allow to dry fully (30–60 seconds).

Only after both sets of steps — hygiene sanitation and nail plate preparation — should gel product be applied.

Tool Sanitation

In a professional salon, all reusable metal tools (cuticle pushers, nippers) must be sterilised between clients using an autoclave or immersed in a professional-grade disinfectant solution (such as Barbicide). Non-porous tools can be safely disinfected this way.

Files and buffers are single-use items for professional salon work — they should not be reused between clients. Keep a stock of individual files and dispose of them after each use.

For Home Users

For home gel polish users, the hygiene steps above still apply. Wash hands thoroughly before application, and wipe nails with a lint-free wipe and nail surface cleanser followed by pH Bond before applying the base coat. The full professional sanitation protocol applies to salon work, but clean hands, clean nail plates and properly dehydrated nails are the key steps for home use.

Frequently Asked Questions

Do I need special nail sanitiser before gel polish?
A professional nail surface cleanser (such as Gelish Nail Surface Cleanse) removes oil and residue from the nail plate more effectively than general hand sanitiser. Use both: hand sanitiser for hygiene, then nail surface cleanser for nail plate preparation.

Can I use alcohol wipes instead of nail surface cleanser before gel polish?
Isopropyl alcohol wipes can work as a nail surface cleanser substitute in a pinch, but professional nail surface cleansers are specifically formulated for this purpose and may perform better. Check the concentration — at least 70% IPA is needed for effective degreasing.

Why does my gel polish lift even though I clean my nails first?
If you're cleaning with hand sanitiser but not following with a nail dehydrator/pH bond, surface moisture may still be present. The nail surface cleanser and pH bond step is what fully prepares the nail plate for adhesion — hand sanitiser alone is not sufficient prep for gel.
