so a 1st test of the wipes I linked, was the aquarium that is in the shower, and this had a thick build up of dried water / soap scum from the shower, along with the bubble popping water dried on the outside of the tank, where the air stones are... most of the front glass was nice, after the 1st cleaning, and the bulk of the water spotting from long term, from the air stones was removed... there is still a small amount on the glass in the thickest areas... I'll give it a day, and wipe them down again, but as bad as some of that was built up, it may require a straight razor to get it clean, then I'm sure a quick wipe, will clean any new build up, if done as i notice it, not a year later...
