Welcome to Tonka Dock Wash, where we arrive by barge to keep your dock and canopies clean and pest free! We pride ourselves in using 100% eco-friendly products as we clean your lake shore and lake shore equipment. We are the only pest control service provider authorized to service docks, lifts, and canopies on Lake Minnetonka! Tonka Dock Wash is a lifesaver! I have always needed my husband to clean the spider webs off of our dock before the kids and I would go out there. Now we do not have to worry about that since we have them treat our dock and lift for spiders monthly!
