Wood Cleaners

Log Wash Liquid Concentrate

Low pH Wood Cleaner

Clean surfaces produce better finishing results. Log Wash removes seasonal buildup before it affects the appearance of exterior wood. It also prepares bare surfaces for stain without upsetting the wood’s natural pH balance.

Routine log home cleaning helps maintain the look of finished wood throughout the year. Log Wash lifts everyday contaminants without the harsh effects associated with bleach-based cleaners. That means less risk of wood fiber damage before applying a fresh finish.

(To treat gray, UV-exposed wood, see Wood Renew).

Shop Available Sizes

One container produces multiple gallons of cleaning solution after dilution. Our log home cleaning products provide an economical option for maintenance without purchasing ready-to-use cleaners.

Product Information

Low pH cleaners offer advantages beyond routine maintenance. This formula is designed to deliver dependable results while supporting the appearance and long-term care of exterior wood surfaces.

Features

  • Gently cleans bare and finished wood
  • Safe for log chinking and sealants
  • Environmentally-friendly
  • Removes dust, pollen, and pollution

How to Store 

Cleaning projects often begin long after the previous one ends. Keep leftover solution in the original container so it is ready when seasonal maintenance returns. Avoid transferring unused products to unmarked containers. 

Application Steps

Streak-free results depend on the direction of application. Apply log wash from the bottom upward before rinsing from the top down with clean water. Dry surfaces completely before moving forward with stain or topcoat application. 

Maintenance 

Avoid routines that permit heavy buildup throughout multiple seasons. Monitor corners, railings, and lower sections where loosened residue can settle again. Shaded walls may need attention sooner than exposed areas. For consistent results, repeat log home cleaning when pollen, dust, or grime begins changing the look of the finish.

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!!

–Jesse

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!!
