Here's a DIY'er tip:
When replacing a light fixture, DON'T disconnect the old fixture at the wire nut connecting the old fixture to the house wiring. The house wiring may have baked insulation from being cooked inside the electrical box and handling that wiring may cause the insulation to break off. Instead, cut the wiring of the old fixture close to the fixture and connect to the old fixture's wires.
Also, when assembling any metal parts where lubricating the parts would be an advantage, but you're reluctant to use a lubricant because dust would stick to it and possibly interfere with the operation of the machinery, remember that glycerine has the lubricating properties of a light oil but evaporates completely without leaving a residue. You can buy glycerine at any pharmacy.
The best way to avoid brush strokes when painting with a brush is to thin your paint. Adding thinner both allows the paint to self level faster and increases the drying time of the paint so that it has more time to self level. Thinning the paint results in it drying to a smaller film thickness, so you need to compensate for thinning by applying an additional coat.
Before painting with any brush, clean it with the thinner of the paint you'll be using. If you'll be using a latex paint, wash the brush out with water. That will allow water to be absorbed by capillary pressure high up into the brush's bristles. This prevents the paint that gets high up in the bristles from drying out while you're painting so that when you do wash the brush out, ALL of the paint comes out easily and quickly. It also prevents "hard heel" syndrome in brushes cause by paint drying high up in the bristles.
Removing a stubborn hinge pin from a door hinge is best done by gripping the head of the hinge pin with a small pair of locking pliers and twisting the hinge pin back and forth in the knuckle while pulling on it.
To prevent faucet knobs from sticking to the top of the faucet stems, apply some antiseize compound to the knob or stem top before screwing the knob on.
You can clean mildewed silicon by mixing bleach and talcum powder (aka: magnesium silicate) to make a paste. Trowel the paste onto the mildewed silicone, cover with Saran Wrap so the bleach doesn't dry out, and leave it for a couple of days like that.
