Oxcon
Iron Stain Treatment

Oxcon (oxalic acid concentrate) is the only effective treatment for rust stains from around nails, spikes, and screws.

Oxcon comes as a concentrate that is diluted with water prior to use. It is best applied using a garden type pump-up sprayer but a brush or broom will also work. Apply a liberal amount to the wood, let it work on the surface for 10 to 15 minutes and rinse it thoroughly with clean water.

Oxcon should not be used for spot cleaning since it may cause blotching of the surface.

Frequently Asked Questions

Cleaner FAQ

Why do I need to wash my log home?

Log homes tend to collect more dirt and debris because of the rounded logs. The top of the log collects debris, making the home look dirty. Log Wash is designed to keep your home looking great and maintaining an excellent finish.

Which cleaner do I need for my log home?

We offer two cleaners, Log Wash and Cedar Wash. Most log homes will use Log Wash, but homes with Cedar, Redwoods, etc., will need Cedar Wash. Read more about choosing the right one here.

How do I treat dark stains or grayed wood?

We offer two products designed to restore the bare wood from stains and weathering – Oxcon and Wood ReNew. Read more about what they do here.

We loved finding a product that we knew would be appropriate for our logs, which were filthy due to putting off washing for too long. The price was better than we expected for a specialty product too. It was recommended on several log home forums, and we’d recommend it too.

I have used Log Wash twice on my house in the last three years. The first to prepare for re-staining and the second as an annual clean up. Both times the product has worked as advertised. Easy to use, easy on and easy off. Clean up was good and no damage to plants around the house. It is definitely one of my favorites.

I attended a Saturday event in Colorado and was so very surprised that my dingy logs were just dirty. I picked up a gallon of the Log Wash and in just an afternoon my home looked like new again! Thanks Perma Chink!!

Wood Renew was recommended through an on-line chat with Perma-Chink as a cleaner for our new to us older log cabin. It had not had any maintenance performed on it in years and had grayed considerably. The Wood Renew along with a pressure washer took away all the dirt, mold, and grayed wood and brought our cabin back to a like new appearance. From that point it was stain, topcoat, and enjoy!!
