Apparatus and method are provided for on-line cleaning of the tubes of a heat exchanger. Tube cleaners are comprised of two members, a rigid flotation member and an elastomeric cleaning member. The cleaner has a selected density to allow uniform distribution through the tubes and to allow recovery by surface extraction or by strainers. Pressures as the cleaner enters or flows along a tube may be measured and selected.
