Question Degreasers for O2 Cleaning

[nikolay_zhelev]

Hi guys,

I'm about to convert my Scubapro MK25Evo and S600 into O2 clean regs for deco stage. I have read several documents for O2 cleaning, however the recommended degreaser products are not available in my country.

I see that in USA, Simple green is frequently used as a degreaser, but back home I can't find it.

I can easily find Meglio and Ethyl Alcohol up to 99% of purity. For european fellow technicians, has anyone used Meglio or Ethyl Alcohol for degreasing? Is there anything against Ethyl Alcohol for metallic and plastic parts degreasing?

Secondly, how do you prepare the second stage for higher O2 concentrations (>40%), as my S600 is mainly plastic and most degreasers are not recommended for plastic parts?

All the best!

Aircraftspruce.eu stock Simple Green Crystal and Extreme for delivery in Europe, at least that's where I got mine from.
