Yes. They all list what not to use. Would i worry about it? No. Use what you need to do the job. If you want, flush it out at the end of the day.Are most manufacturers the same as mytee when it comes to voiding the warranty if rinse agents are used in the fresh tank of a portable? It also mentions something about the Hydroxy also. So
are there any specific rinse agents that would be warranty acceptable to these machines?
