FIND OUT A LITTLE ABOUT US

Kleen Tank of Southwestern Washington is just one of a family of Authorized Kleen Tank Dealers, owned by Mark Johnson. We are located in Olympia, Washington and servicing the Washington cities and surrounding communities of Seattle, Bellevue, Tacoma, Bremerton, Olympia, Centralia, Kelso/Longview, Vancouver, Yakima, and the Southwest Washington Coast. In Oregon, we service Portland, Hood River, Astoria, and the Northwest Oregon Coast. We will also make occasional service trips to Central and Eastern Washington.

We currently live and travel in our 2005 Airstream Land Yacht 30SLX motorcoach. We look forward to helping and educating RVers as we travel or stay in our home area. We enjoy talking with other RVers because they are a friendly group of people who enjoy social interaction and are always ready to share their experiences with you. 

I started my Kleen Tank business because I felt it was time to start working for myself again instead of somebody else. I saw the business opportunity of Kleen Tank as something that is vital to all RVs and his beneficial to everyone that has an RV, I myself saw the need for maintaining my rig and the best possible condition, and that includes deep cleaning the holding tanks. What drew me to Kleen Tank was the focus on training of fellow RVers in the maintenance of their holding tanks and the values of the company as a whole. All of the Kleen Tank dealers work together as a family, and that was important to me.

We’re always glad to hear from RVers with questions and inquiries and as we travel, be sure to see where we’re at (or going to be!) so we can meet up and even schedule your RV for a professional tank cleaning. You can call us anytime or reach out to us online. Thanks and we’ll see you “out there.”
