To whom it may concern,

Over the past 20 years, we have had fair success treating our black water tanks with formaldehyde-based popular national brand deodorizers.

Recently, however, in an attempt to become more environmentally friendly, we experimented with several Green brands but were unhappy with the results until we tried Clearoma™. Clearoma™ is particularly successful in combating the unpleasant odor associated with black water storage (no odor escapes from our black water tank when we flush the toilet and the tank empties easily when required).

This product completely eliminates holding tank odors.

We have no hesitation in recommending Clearoma™ to our friends.

Sincerely,
Mel and Lorraine Nelson
