A new roof is a big project.
Roof visualization tools work pretty well.
Roof replacement is a big project. Definitely not DIY, for me anyway.

It’s amazing how well lemon works to remove hard water stains.
We have a toilet in the basement that does not get used very often. That means it does not get flushed often, either. Over time, hard water stains build up. as shown in the lower right picture above. This ring is created by hard water.
According to Wikipedia, hard water is water with a high mineral content. Calgary has some of the highest hard water of all Canadian cities except Regina – lots of calcium and magnesium. This is a common problem across the Canadian prairies, some parts of Ontario and most of the United States. As the water in the bowl evaporates, calcium carbonate is left behind as hard water stains.
Since we are expecting a house full of guests over the Easter weekend, I decided (well, my wife did really) that it was time to clean up the basement toilet and remove the hard water stains.
I went looking for advice on the Internet. The first suggestion I found was pumice stone. But I was worried that this would leave scratches on the toilet bowl. This was confirmed with a small test. The second suggestion was lemon and salt. This worked great.
The lemon creates a chemical action which dissolves the minerals. The salt acts as a mild abrasive. It took a few lemons, lots of salt, and plenty of elbow grease and patience. As you can see in the four pictures above, starting with the “before” in the lower right and the “after” in the upper right, hard rubbing with a salted lemon gradually removed all of the hard water stains.
Two tips. Wear rubber gloves. Turn the water off to the toilet. Before you begin rubbing, flush the toilet. Since the water is turned off, the bowl will not refill. That way the water is kept off the hard water stains while you work on them.
Why does lemon remove hard water stains?
It’s all about the citric acid, which converts calcium carbonate into a soluble solution that can be wiped away. According to this explanation, calcium carbonate has a high ph content. The lemon neutralizes the ph, dissolving the adhesion between the scale and the solid surface. The citric acid in a lemon is pretty weak. But it is strong enough to remove hard water stains from a toilet.

Throwing snow is easy with an electric snow shovel.
Every year, we decorate for Christmas. Every year, I have to repair a few Christmas decorations.

Halloween usually marks the arrival of winter in Western Canada. And winter means snow. And snow means I get to use my electric snow thrower.
