I have a concrete pad behind my appartment but were not aloud to use pressure washers...it has black dots on it and i'm thinking that it's mold. How to I remove it?

Answer
1 cup bleach per 5 gallons of water. Use a broom to sweep it on and let it set for about 10 minutes and then rinse it off while brushing it with a bristle broom.

How do you clean out the inside of an exhaust pipe?

A Williams

I recently hydroplaned off the road into mud and got a good bit of mud pretty deep inside my exhaust pipe. No damage on the car, but just a lot of mud! I don't really want to run water in my exhaust without knowing what other people do first so what should I do?

Answer
I would use a high pressure washer and a broom stick to break it up. Once u get a hole started it the mud, start ur car up so u can clean the water out.
