Welcome back to Door Innovation’s series on common things that can corrode your door — this week’s topic is something everyone should look out for. If you’re in a coastal area, be sure to look over last week’s discussion of just how much damage to your door frame sea salt can do. It’s the chemistry behind salt that causes corroded metal door frames, and we’ll be talking about a similar thing this week.
The Question: Are Common Chemicals Behind My Corroded Metal Door Frame?
Many chemicals float around our urban environments. The road salt discussed the other week — also known as sodium chloride, with additives like iodine — is a big example, but what gets left behind from our cleaning products is likely the biggest.
The Answer: It’s Very Likely
Let’s look at a chemical called sodium hydroxide, also known as lye. It’s known in pop culture for dissolving things, but this chemical is also found in nearly every bar of soap out there, along with many cleaning products.
How Does Lye Cause Corrosion?
Lye is one of the most basic compounds out there. Its pH is extremely high, making it more caustic than ammonia and bleach. High-pH substances have lots of free hydrogen ions. When they come into contact with a surface, they’ll attach to the surface, producing corrosion — the unsightly, orange stuff on a corroded door frame.
What Common Sources of Lye Should I Know About?
When shopping for cleaning products, either avoid products that mention “sodium hydroxide” or make a point of washing down thoroughly after using it. Lye-based cleaners often advertise themselves as “non-caustic” — but you don’t need to turn to the strongest base on the market for something non-caustic. Natural enzymes accomplish the same task without sucking the life from your door frame.
It might be impossible to entirely avoid lye. It’s also used in cement, mortars, and concrete.
What If There’s Already Corrosion?
That’s where Door Innovation comes in. Replacing a whole door frame is expensive — to the tune of $2,000. Take matters into your own hands with the Jamb Patch. Just cut out the corroded area and attach the Jamb Patch to restore your door to its full function and contain corrosion. This afternoon fix will save you time and money on your door repair — and even more in security.
