I have been using dawn ultra but I really haven't paid much attention to the different types of dawn . I just don't want scented soap. I guess I should look at them closer. if you think it may be too strong then premix some drops in a plastic tub to wash your masks.
I have to wash my glasses 5 to 6 times a day to get face oil off them , this heat makes it bad. I just had one eye surgery completed for new lens the other eye will be done by sept. Then I hope only sunglasses will be needed.
That's how I got started with dawn-- cleaning glasses.
I have noticed different labeling at times but I will look closer. I use it in my garden to keep ants out of the pots and pill bugs out of the mulch . They say it kills ants. I know it stopped my ant problem .
You will find that once you clean oil off and use a mask liner there will be very little oil on mask and cushions . It absorbs it and moisture ,feels good and mask doesn't slide much on your face when you toss and turn . Then it is easier to clean .
Hope you have as good results.
Dawn Ultra works great for mask cleaning. It hasn't shortened the life of my mask, which has lasted an unusually long time. I got a year out of my last mask cushion. I gave up on it because it eventually picked up a sweaty odor that I couldn't get rid of, but it was still working well with minimal leaks. I also use baking soda and Control III disinfectant to clean it, sequentially, not mixed together. I can't stand a dirty mask, although I use a mask wipe about half the time since I think daily cleaning is overkill.
Dawn Ultra does a fine job - I never dilute it. What you want to avoid is any dishwashing liquid with moisturizers in them. Quite a few of the dishwashing liquids on the shelf at the store have hand lotions and stuff in them - these are what you want to steer clear of.
