How to Remove the Stain from Superglue from Quartz Countertop

Superglue (cyanoacrylate) is a fast-drying adhesive that firmly bonds surfaces together. While super handy, spills and drips can leave behind stubborn stains on surfaces like quartz countertops. Removing superglue stains takes a bit of effort, but it can be done with the right techniques and products.

What Causes Superglue Stains on Quartz?

The cyanoacrylate in superglue undergoes a rapid polymerization reaction when it comes into contact with moisture. This cure process turns the superglue into a hardened plastic resin that strongly bonds to surfaces.

On porous materials like wood and paper, superglue seeps in and creates a permanent bond. But quartz countertops are non-porous, so the glue remains on the surface. However, it still adheres quite stubbornly.

Superglue stains on quartz have a whitish, opaque appearance that stands out against the sleek surface. The glue residue resists washing and scrubbing, requiring solvents to break it down.

Step-by-Step Guide to Removing Dried Superglue from Quartz

Removing stubborn superglue stains from quartz countertops takes patience and the right set of supplies. Here is a step-by-step process:

Gather the Right Cleaning Supplies

  • Acetone nail polish remover
  • Non-abrasive scrub sponges
  • Soft cloths
  • Eye protection, gloves, and ventilation

Avoid using abrasive scouring pads or powders that could scratch the quartz surface. Acetone-based nail polish remover will dissolve cyanoacrylate residues without etching or dulling the finish.

Loosen the Stain

Start by softening up the glue stain to make it easier to remove.

  1. Apply a generous amount of acetone directly onto the stain. Let it sit for 2-3 minutes.
  2. Gently rub the area with a soft scrub sponge or cloth soaked in acetone. Take care not to scrub too vigorously.
  3. As the acetone breaks down the glue, you will notice the stain slowly lifting. Re-apply more remover as needed.
  4. Once the stain appears loosened, switch to a clean soft cloth to lightly blot up any excess acetone and residue.

Remove Remaining Traces

After loosening the worst of the stain, trace residues may still remain. Repeat the process to fully remove:

  1. Re-apply acetone and let it penetrate for 2-3 minutes.
  2. Use a scrub sponge soaked in remover to gently rub off any remaining stain or haze.
  3. Switch to a clean soft cloth to wipe away remnants as they dissolve.
  4. Rinse the area with water and dry thoroughly once the stain is gone.

Take your time during this process. It may take several applications and scrubbing sessions to completely erase stubborn superglue stains from quartz.

Tips for Avoiding Superglue Stains

Preventing superglue stains in the first place is easier than removing them. Here are some tips:

  • Apply superglue carefully onto surfaces, not all over fingers. Wipe hands before touching quartz.
  • Cover surrounding areas with paper or plastic sheeting when gluing.
  • Transfer liquids like activators into a small dish instead of working straight from bottles.
  • Clean up spills and drips immediately with acetone. Don’t let glue cure on quartz.
  • When possible, glue materials together on a separate work surface, not directly on the countertop.

Can Superglue Permanently Stain Quartz?

If left for prolonged periods, superglue stains can become very stubborn on quartz. But with the right solvent and techniques, even old dried glue should come off.

Acetone is highly effective at dissolving cyanoacrylate polymers. Coupled with gentle scrubbing, it can remove even set-in superglue without damaging the durable quartz surface.

With some perseverance and the steps above, you can get quartz looking flawless again after even the worst superglue stains. Just be sure to take precautions to avoid glue mishaps in the future.

Frequently Asked Questions

What household products can remove dried superglue from quartz?

Acetone-based nail polish remover is the most effective and safe homemade option. Avoid abrasive cleaners that could scratch quartz.

How do you get old, dried superglue stains off a countertop?

Soften the stain by soaking it in acetone for 2-3 minutes. Gently rub with a sponge or soft cloth dipped in acetone. Repeat as needed until removed.

What removes superglue from surfaces?

Chemical solvents like acetone, mineral spirits, and paint thinner can dissolve cured superglue. They break down the cyanoacrylate polymers.

Can you use rubbing alcohol to get superglue off quartz?

Rubbing alcohol lacks the strength to dissolve superglue. Stick to pure acetone nail polish remover instead.

Does WD-40 remove super glue?

Yes, WD-40 can be used to soften superglue for removal from non-porous surfaces like quartz. Spray it on, let it soak, then gently wipe.


Superglue stains can happen easily, but don’t ruin your quartz countertop. With the proper solvent like acetone and some scrubbing, the dried glue can be safely removed without damaging the surface. Take your time, follow safe procedures, and you can erase the evidence of any superglue mishaps on quartz. Just be more careful when using this sticky adhesive in the future!
