Cleaning and Stain Removal - Cleaning Plastic molded chairs?

Hello, how do you clean those molded plastic/PVC type chairs (not pipe) that you see at Lowe's and Home depot?
My neighbor has tried Simple Greene, Detergents, 409, and some stuff I never heard of!!
Bleach will leave a deposit like chalk that gets on your clothes, what a mess!

Suggestions, wide open, I will be the interpreter between her and you guys!

You may want to try a protein cleaner for any mold/mildew issues. I would suggest going with a quality citris based cleaner. Giving both the above mentioned dwell times before cleaning is the key. 10-15 mins Just do not let dry.

Do you mean some of the orange stuff you see advertised on TV? Is the protein cleaner the same stuff or, are you talking about something different?

I wouldnt go with anything advertised on tv, a lot of that stuff is watered down. You can check at your local home improvement store for a quality citris based cleaner. I wouldnt get it from a dollar store or something like that. A protein cleaner is different. It uses protein material to break down organic soils. You can also find them at pet stores or local home improvement stores.

I am going to contact the University of Maryland with the same question.

If all-purpose cleaners are not effective, then chances are that staining of plastic patio furniture is permanent. Plastic (PVC) tends to porous and absorbent of stains. Patio furniture succumbs to air pollution, UVB rays, etc. You can try using a mild abrasive cleaner in powdered or liquid form. You can also try chlorine bleach products. But chances are great that you will not restore PVC patio furniture to its 'like new' condition. If you do manage to get the furniture clean, please seal with auto wax for protection and sheeting action and to prevent chaulking (oxidation).

Thank you for the informayion.
