SlimmSnake,
This is a very good question. The short answer is yes, there is another reason for wiping down the glass other than to remove algae. The in-depth answer involves the whole reasoning behind why large water changes and tank maintenance is necessary for healthy discus. It all involves organic compounds that are present in food. Organic compounds are not toxic to the fish, however two undesirable things occur when they are introduced. First, there are pathogens (bacteria, virsus, and parasites) present in every aquarium. These multiply greatly when they feed on the food. Second, the food decomposes and this process produces other compounds that are toxic to the fish. These toxins cause stress on the fish, and that makes them more vulnerable to attack by the pathogens. It's important to know that this is occurring in the tank even if the water appears crystal clean.
When food is placed in the tank it is transported in the water column and adheres to the glass and everything else in the tank. This is where a large portion of the pathogens exist and where decomposition occurs. A good indicator that decomposition is present can be attained by removing something (decor, artificial plants or whatever) from the tank and giving it the "sniff test" by holding it close to your nose. A foul odor indicates the presence of decomposing organic material. Decomposition is a common process in nature as evident by the foul smell of a dead animal or decaying vegetation. I wonder if discus can smell, and how it affects them if they can.
The number one purpose of large water changes and tank maintenance is to reduce the amount of food available to the pathogens (thus limit their number) and to reduce the toxins that result from decomposition (thus reducing stress). A more detailed explanation of this is provided in the following link:

There's more to the story about organic compounds. I have a non-planted show tank with adult discus, and have implemented a filtration system that strips the water column of nearly all of the organic compounds. This is accomplished with the use of a product called Purigen. Purigen absorbs organic compounds, and it is very effective at doing so when used in a reactor. With this I have achieved what I consider very good results. Other than water changes, the only other tank maintenance that I do is done once a month. Uneaten food and feces are automatically removed by the filtration system. Decomposition has been reduced to the point where the tank remains pristine clean without any intervention on my part, other than a monthly cleaning. Algae is completely eliminated and the glass, bottom, and decor remain spotless for an entire month. Bassically what happens is that once the organic compounds are eliminated, the tank stays clean. Here's a link that illustrates the results that have been achieved, along with the method implemented to achieve these results

The above link has several stickies at the top. The results achieved are contained in Parts 2 and 3. The filtration system is explained in Parts 4 and 5. Please be advised that it takes more than just the addition of a Pruigen reactor to achieve the results.
Another thing that the above filtration system permits is to achieve a nice looking bare bottom tank. Some people might not think so, but I like my bare bottom tank so much that I prefer it to a substrate. Here's a link showing the results:
