we currently have 8 filters betwen the 3 bikes we own 2 OEM, 1 Twin Air and 5 Uni Filters, all these filters see the same treatment for cleaning and oiling.
The no-toil/uni-filter rumor is just that, a rumor. I've been using the same uni-filters for years with no problems. In fact I prefer the uni's to the no-toil filters.
Are uni filters the ones that are separate foams that you can take apart? if they are I did have them come apart using notoil and the washing machine.
I am not sure if it was the hot water in the heavy duty cleaning cycle, the no toil itself or the combination. Had no problems with a stock filter,twin air? or white bros filters though with the same care.
5 air filters and shop/polishing cloths and buffing wheel bonnets get washed then I scrub down the basket and washed again then my work clothes go in, stop washer after the first cycle scrub down the basket again and rewashed then I move onto the socks, underware and work tshirts. Its usually a full day event just to open the garage doors for one week.
