For sanding in odd-shaped spots, try stretching a piece of sandpaper over the side of a deck of playing cards. The cards can be pushed sideways into the pattern to give the sandpaper the appropriate shape.
My fiberglass shingles grow a fungus that I treat with bleach every year or so. Is this safe for the shingles, and is there any way to prevent this after cleaning?
Bleach shouldn't harm the shingles. Scrubbing with a brush can remove particles on the surface. Usually, an area where you have this problem has a moisture problem because of a lack of good air circulation or exposure to the sun. If you have foliage that grows up over the roof, you should try to prune it to allow for better air movement.
I've never really taken care of my lawn mower, but I feel I should. What can I do before I get it out this season?
Check your owner's manual before doing anything because models vary.
Pull the wire off the spark plug and make sure it can't make contact while you are working with the mower. Replace or regap the spark plug to specifications and reinstall it. Don't reinstall the plug wire until you are finished servicing the mower.
Your air filter will need to be cleaned or replaced. Many of the foam types can be cleaned, oiled and reused.
The carburetor could probably benefit from a shot of carburetor cleaner, which will clean away some of the grease and debris and lubricate the moving parts. Check other moving pasts to see whether they need a shot of oil.
Blades should be kept sharp. You can remove the blade and sharpen it yourself. It's really simple to sharpen; a file will do the job.
Is there a safe way to remove rust stains from a porcelain sink?
Here are two safe ways to remove rust. Oxalic acid, which is the base for many wood-bleaching products, can be made into a paste, applied to the spots and left to dry. Or, make a paste of cream of tartar and peroxide and do the same thing. Peroxide for hair is a little stronger than hydrogen peroxide.
After washing my car, I noticed that some corrosion from the battery leaked onto and stained my one-year-old concrete driveway. How can I get this off and prevent more later?
Treat it as you would a rust spot. Oxalic acid can do a good job. On concrete, make a paste and scour it with a brush. Also, the rust-remover compounds made for metal, in either liquid or jelly form, will work on concrete.
