I usually wipe them off regularly, like you. If you leave them be they can harden and it can be a pain to get off. Vinegar usually works well for hardened mineral deposits.
very true and I agree it is probably mineral deposits. Test your water and tell us how hard it is. Make sure you dont actually pour vinegar into the tank...you could cause pH fluctuations. There is nothing wrong with taking the filter out though and cleaning it...Melafix works well too.
My test strip states that the water is 75 GH, between 180 - 300 KH, and 8.4 PH.
