How to remove paint from glass

A fresh coat of paint on window and door frames is a simple way to update your home’s interior and exterior to increase its appeal, but it can be difficult to paint around glass without having to paint the glass itself. Achieving a clear transition from the painted surface to the glass is key to making a DIY paint job look professional, so it’s worth the effort to keep the paint off a glass window or door—and remove any paint that ends up on the glass as soon as possible.

Why you should skip the painters tape

There are several ways to remove paint from glass, but nothing is easier than not painting the glass in the first place – or does it exist? You might think that gluing the glass is the best way to prevent paint from seeping onto the glass, but that’s not the case. In fact, it may surprise you to learn that professional painters rarely use painters tape at all. Not only is registering with this app not as efficient as you might think, but it is also time consuming and expensive. Oftentimes, once you remove the tape, you’ll still find smudges and bits that need to be removed, no matter how fine the paint is.



How to remove paint from glass with a razor blade

When painting smooth glass doors, window frames, mirror frames, or any other item that features smooth glass, you won’t need any fancy products or tools to remove paint from glass. In fact, all you need is a sharp knife and a razor blade scraper.


This method is only recommended for standard latex paint. Specialized paints, primers, and oil paints will stick better to glass, making them more difficult to remove using this method.


Here’s how to quickly remove latex paint from glass with a razor blade.


What will you need

  • glass cleaner
  • Tissue paper
  • multi-use knife
  • razor blade scraper


Step 1: Clean the glass

It is much easier to remove paint from clean glass, since there are no foreign bodies that the paint can stick to. Before painting, clean the glass with regular glass cleaner and a paper towel.


Step 2: Paint the frame

Paint the frame with latex paint and let it dry.


Editor’s tip: While removing latex paint from glass isn’t the most difficult task, reducing the amount of paint you get on the glass will save you some time in the long run.


Step 3: Record the edges

Use a utility knife to score the edges of the glass. This will prevent any paint from pulling off the frame, resulting in clean, crisp lines.


Step 4: Scrape the glass

Use a portable razor blade scraper set at a 45-degree angle to scrape the paint off the glass surface. Scrape toward the tire to prevent damage to the tire finish.


warning: When scraping glass with a razor blade scraper, always hold the scraper flat against the glass, and move forward in a steady, straight motion. Moving from side to side or holding the scraper incorrectly can scratch the glass.


Follow up with glass cleaner for a perfectly clean shine.
