  1. Where do you guys buy your oxalic acid from? I get it from the Chemistry Store- 38lb for $140. Any cheaper places available? Also, what type of sprayer/method do you use to apply the acid? I use a pump up sprayer, but it takes too long for large areas of concrete.

    Thanks,

  2. Thanks Shawn, I just bougt the unit last week- brand new. Maybe it sat idle at the manufacturer for awhile. Is there a cleaner that I can run through the engine. I am no mechanic. Also, spoke with a rep at the manufacturer who said some crap about the reason this surging occurs is because the engines are being made to comply with EPA/emissions regulations. As a result, this surging may occur due to the modifications. I don't buy it.


  3. Hi, I am looking for a product to remove black streak from the white painted wood of a pergola. Not sure where they came from- could be from the metal rooftop. I've tried gutter grenade which works great on al. gutters, but it doesn't touch these streaks. Anyone recommend a product?

    Thanks,
