I have an '04 210 that has never been as clean as it is after using this for the first time yesterday! The best part, besides coming clean, is you don't have to work the brush hard to get results. Being in dry dock for the better part of the past too-many months had built up a pretty bad case of mildew. This stuff cut right through it. I only had one cushion which did not come completely clean. Now it's time to splash it and get some slime on it.
