One of our readers cleans her siding but is getting residue when she does. Can you help?

 

I have had vinyl siding on my house over 20 years. To clean it I use bleach and water. Let it set for 5 minutes, then rinse. I do this once a year. I noticed that when it dries you can take your hand or fingers and a chaulk film the same color of the siding is on my finger or hand. What can I do? My siding color is beige like a wood grain. The front of the house does get a lot of sun.

I used to work at a wholesale building supply store and we sold a lot of vinyl siding.  The chalkiness on the siding is a problem that will never go away.  See if they still have a warranty on the siding (probably not if its over 20 yrs old).  Like roofing the product wears out and goes bad.  It's time to consider residing the house.
