How to Dissolve Window Putty

If a window pane starts to rattle in the wind, you know that it’s time to repair it. The pane itself may be perfectly good, so its the putty that needs altering. When window putty ages, it becomes hard and difficult to remove by scraping. Because window putty is made up of linseed oil and oil, this technique employs a mix of linseed oil and bleach to break down the material and make is easy to eliminate.

In a clean container, combine one spoonful of household bleach with one pint of linseed oil.

Apply the bleach/linseed oil mix to the putty so that the putty gets quite wet. Wait one hour before applying another coat. Wait 24 hours.

Examine the putty by scraping at it with a putty removal instrument. If the putty does not disintegrate rapidly or scrape off easily, apply another coat of the mixture and wait for another 24 hours.

Examine the putty. If the putty is still not dissolved, continue employing the mix before the putty dissolves.

Sand wooden window elements to ensure a fresh, smooth bonding coating to get new putty.
