Over time, a lot of the hardware around your home can get old, worn down, and uncomfortable to use. If you've got a few handles or taps that have seen better days, you can fix up their grip with a bit of Sugru mouldable silicone.
Sugru is great for all sorts of DIY repairs, but we thought this one was pretty clever. Just take a good handful of Sugru and cover up any old, rusty piece of hardware to give it a better grip, and make it feel a little less dirty. It works on a lot more than just taps, too — anything that's gotten old, rusty or sharp can be fixed up with just a bit of the mouldable putty.
