What can I use to scratch a card?

There are a variety of household items that can be used to scratch off lottery tickets, gift cards, and other types of scratch cards. The key is to use something with a sharp edge that can scrape away the covering on the card to reveal the hidden numbers or symbols underneath. Some common scratching tools include coins, keys, fingernails, knives, razors, and even sandpaper.

When choosing a scratching device, it’s important to consider the thickness of the covered area on the card. Thinner coverings require a thinner scratching tool so you don’t scratch too deeply and damage the card underneath. Foil or latex coverings are very delicate and require gentler abrasion. For these, fingernails, coins, or light sandpaper are better options. Cards with thicker coverings like some phone cards can handle rougher scratching with keys, knives, or razors.

It’s also important to consider the size of the tool. Larger tools like house keys are ideal for scratching off large areas. Smaller precision tools like thumb tacks allow you to carefully scratch off thin strips or small sections if needed. Most lottery scratch cards have a thin latex covering that can be easily scratched away with commonly found household items.

Using Coins to Scratch Cards

Coins are one of the most commonly used household items for scratching lottery tickets and prepaid cards. They are small, easy to handle, and readily available. The ridges on the edges of coins are perfect for scraping off thin coverings. Both large and small denomination coins will work. Larger coins like quarters or nickels cover more surface area while dimes and pennies can be more precise. The important thing is to use the thin edge of the coin, not the flat surface.

To scratch smoothly, hold the coin between your thumb and forefinger and scrape in a straight line, applying light to medium pressure. Don’t use too much force or you could tear through the covering completely. Make sure to scratch off the entire area, using overlapping strokes and rotating the coin occasionally to use a sharp edge.

Quarters are ideal for larger scratch cards like holiday lottery tickets or phone cards. A quarter can remove the coating quickly from a large surface area. Nickels, dimes, and pennies all work well for smaller cards or getting into corners and edges. The ridges around the perimeter of the coin do the scratching. If your coin isn’t scratching well, try a different coin or angle the coin so a sharper ridge makes contact with the card.

Using Keys

House or car keys are another great option for scratching prepaid cards and lottery tickets. The teeth of the key provide the perfect abrasive edge to scrape off thin coverings. Keys are easy to handle and allow you to apply controlled pressure. You can use either small keys like house keys, mailbox keys, or padlock keys or larger car or door keys. The size you choose depends on the size of the area you need to scratch.

For smaller cards, use a smaller key, holding it perpendicular to the card and scraping in strokes. Apply light pressure and scrape in different directions to remove the covering. Small keys let you target specific areas and scratch precisely.

For larger cards or to scratch off a bigger area, use a large key held at about a 45-degree angle to the card. Scrape across the card using the teeth of the key to scratch away the coating. Apply a little more pressure but not enough to tear all the way through. The teeth will cut through the latex or foil as you scrape.

The nice thing about keys is that you can easily apply just enough pressure to scratch without cutting the card or surface below. Make sure to use the thin edge of the key head, not the thicker base. For stubborn spots, you can use the tip of the key. Metal keys tend to work better than plastic.

Using Knives and Razors

For cards with thicker scratch-off coatings, a knife or razor blade may work better than coins or keys. These tools are designed to cut precisely and can scrape through tougher materials. However, you need to be more careful when using sharp objects.

To safely scratch a card with a knife or razor, hold the blade flat against the card and scrape using light pressure and short strokes. Pull the blade across the surface at a shallow angle rather than trying to cut straight down through the covering. Apply just enough pressure for the ultra-thin blade to slice through the latex or foil.

Utility knives, paring knives, pocket knives, and X-ACTO knives all work well. Make sure the blade is sharp. Dull blades won’t scratch cleanly. Be very careful of your fingers and surfaces below the card when using any sharp object.

Single edge razor blades are ideal for precision scratching. Break off a new sharp segment of the blade to use. Hold the razor nearly flat and scrape off the covering in swipes. Razors allow you to target tiny areas and get right next to edges.

Never cut toward yourself and keep fingers clear of the path of the blade. Take your time and apply minimal pressure. Knives and razors should only be used by adults or with adult supervision. They require extra caution but can scratch through surfaces other tools can’t handle.

Using Sandpaper

Fine grit sandpaper is another option for scratching stubborn scratch-off coverings. The abrasive surface of the sandpaper wears away the coating as you rub. Sandpaper works similarly to using a coin but is better for cards with thicker latex. It takes longer than a blade but is safer than a knife or razor.

For the best control, use fine sandpaper with at least 200 grit. Cut or fold a piece to fit the size of your card. Hold the sandpaper in your fingers and rub it back and forth across the surface. Apply light pressure and be patient. The sandpaper will slowly wear away the material.

You can also try rubbing the card gently on a sheet of sandpaper laid on a table. This lets you use your weight and arms to apply even pressure as you slide the card across the abrasive surface. Concentrate on small areas at a time.

Sandpaper scratching is messier than other methods and leaves behind visible scrape marks and paper residue. You may need to wipe debris off the card periodically so you can see the numbers emerging. But sandpaper reliably scratches through coverings other household items can’t handle.

Using Fingernails

For latex or foil scratch cards with very thin coverings, your own fingernails may be enough to scratch off the coating. Using fingernails is ideal for cards where you only need to scratch off a small area, like on some lottery tickets. Fingernails provide precision without any tools.

To scratch with a fingernail, hold the card steady with one hand. With the index finger or thumb of your other hand, scrape your nail repeatedly over the latex coating. Apply light pressure and scrape at a 45-degree angle using the edge of your nail. Make small circular motions or back-and-forth scratches.

Keep scratching the same spot to wear down through the thin covering rather than trying to scratch off long strips at once. Rotate your finger occasionally to use a sharper nail edge. Use the hand supporting the card to stretch the latex taught for cleaner scratching.

Fingernails work well for scratching lottery tickets but won’t handle thicker coverings. Your results depend on how long and strong your natural nails are. Acrylic nails are too thick. Use a coin or sharp blade for plastic phone cards or thick latex. But for lottery tickets at home, your own nails may be the perfect scratching tool.

Choosing the Right Scratching Tool

When faced with the need to scratch off a prepaid card or lottery ticket, look closely at the type of covering first. Thin latex sheets take less abrasion than hard plastic or thick foil. Examine the size of the area you’ll need to scratch. A large surface calls for a quarter or large key while a small target needs a razor blade or dime.

Test an inconspicuous corner first if you’re unsure of the covering durability. Scratch lightly with your fingernail. If the coating comes up easily, a fingernail, penny or sandpaper will work. If not, try a metal coin, knife or key. Thick phone card coatings may even need sandpaper or razors.

Ideally, choose a tool that allows good control so you can scratch precisely without damaging the card. Look around your home or pockets for handy items like coins, keys, blades, or sandpaper. Most prepaid and lottery cards only require light abrasion from the edge of a small common household object. With the right scratching tool, you can easily uncover the hidden contents.

Tips for Scratching Successfully

Here are some top tips for scratching gift cards, lottery tickets, and other cards cleanly:

– Identify the type of scratch-off coating – latex, foil, or plastic. Start gently if uncertain.

– Select a tool with the right abrasiveness for the covering. Sharp for thick coatings.

– Use the thin edge or point, not the broad flat surface.

– Keep the tool at an angle to the card for the most control.

– Apply light to medium pressure and scratch in small strokes.

– Target one small area at a time, removing the coating before moving on.

– Adjust pressure and tools if needed based on how easily the covering scratches away.

– Choose precision tools like razors for small areas and big tools like coins for large areas.

– Scratch lines can overlap but avoid digging into one spot as it can damage the card.

– Wipe away any plastic or foil debris as you scratch to clearly see the numbers.

With the right scratching technique, you can successfully uncover the hidden contents on any prepaid or lottery card using common household items. Start gently and adjust pressure and tools as needed until you scratch through the protective coating.

Safety Tips

Scratching cards with household items is generally safe but here are some tips for staying safe:

– Use care with sharp tools like X-ACTO knives, razors, and paring knives. Keep fingers behind the blade and scratch on a stable surface.

– Supervise children who are scratching and don’t let them use sharp metal tools.

– Scratch lightly at first if you aren’t sure how durable the card covering is.

– Make sure your scratching tool stays perpendicular to the card to avoid slipping and cutting yourself.

– Discard blades safely in the trash after using razors or utility knives.

– Clean debris off scratch cards periodically to maintain control and visibility.

– Work on a table or over a lap to catch any scratched-off pieces that detach.

– Scratch away from your body.

By being cautious with sharp objects and controlling your scratching force and direction, you can safely reveal hidden codes and symbols. Just take your time and remember that a little pressure goes a long way.

Alternatives to Scratching

Although scratching is the most common method, there are some alternative ways to reveal the information under scratch-off coverings:

– Lightly dampen a cloth with rubbing alcohol and gently rub it across the scratch-off coating. This will dissolve the latex or foil.

– Use an air duster can (or compressed air if available) to freeze then crack off the scratch-off material.

– Place scotch tape over the area, smooth it down, then lift quickly to pull up the coating.

– Heat a pin with a lighter then melt the coating away dot by dot.

– Soak off water-soluble scratch coatings by running the card under hot water. Dry immediately after.

– Use a hair dryer on a low heat setting to soften and scratch away the coating.

– Dab nail polish remover on the coating with a cotton ball or pad to dissolve it.

– Rub petroleum jelly vigorously on the covered area to abrasively remove the coating.

However, normal household scratching is still the easiest, most accessible method overall for revealing covered data. With the right tool and technique, scratching cards is quick and effective.


Scratching prepaid cards, lottery tickets, and other items with hidden data underneath protective coatings can easily be accomplished using common household objects. The key is matching the right tool to the type of scratch-off covering on the card. Harder plastic or thicker foil requires more abrasive scratching with knives, razors, or sandpaper while latex and thin foil can be scratched off with fingernails, coins, keys, or other household objects with dull edges. The optimal tool for any situation should allow control and precision without damaging the card underneath. With the right scratching technique, you can successfully uncover hidden information and codes. Just remember to scratch gently at first and adjust pressure as needed.
