X3 plus maybe he was thinking of a TPO roof

CLEANING AND MAINTAINING THE ALPHA SYSTEMS ROOF MEMBRANE

Proper care and maintenance of your Alpha Systems roof membrane is critical for years of trouble-free performance. Normal maintenance is simple, easy and requires no special materials.

Periodic cleaning (three to four times per year) is the primary maintenance required. Alpha Systems recommends using a non-abrasive household cleaner, such as Top Job or Spic-N-Span, and a medium-bristled scrub brush. Do not use any harsh or highly-abrasive products during cleaning. When finished cleaning, remember to thoroughly rinse the roof and sidewalls in order to remove any soap residue and to prevent streaking. CARE SHOULD BE EXERCISED WHEN WORKING ON TOP OF YOUR UNIT! THE ROOF MAY BECOME SLIPPERY WHEN WET.


DO NOT USE ACETONE, OR ANY OTHER PRODUCTS CONTAINING PETROLEUM DISTILLATES, ON THE ALPHA SYSTEMS ROOF MEMBRANE. USE OF THESE PRODUCTS WILL DAMAGE THE MEMBRANE.


Periodic inspection of the roof, during cleaning, is highly recommended. Check the membrane for signs of damage. Check the caulk/lap sealant used in all termination areas, and around all accessories and fasteners, for signs of cracking or voids.

The roof membrane can be cut or punctured by sharp objects. Caution should be used when placing any articles on the roof. If damage does occur, the membrane can usually be patched.

Alpha's membrane is quite inert and will resist weathering well. It does not require the periodic application of products to protect it from ultra-violet light or ozone. In fact, these products can often cause damage to the roof membrane.

If you have any questions, please contact Alpha Systems at 574-295-5206.

Then ... neither he nor you read what the subject of this thread is about "what does fresh epdm look like?". Your wordy treatise on TPO cleaning also has nothing to do with the compatibility of the actual material being discussed here and acetone and as such is just noise or the proverbial "red herring". IMO one has a DUTY to post only what they know or believe they have a reason to believe something is true and if not close to 100% sure make sure they clearly state the potential for what they are saying might not be correct. As I CORRECTLY point out acetone is not a good general cleaning agent even on EPDM roofs because of its permeability and effect on the glue that holds the EPDM to the substrate. The cleaning instructions/recommendations for EPDM just like TPO warn against using petroleum distillates, but still has nothing to do with the information that I would still in the future call HOGWASH that acetone dissolves in this case "EPDM" rubber. I never attacked the poster personally, only the BUM and MISLEADING INFORMATION that he/she presented so I'm not sure what civility has anything to do with anything here. If one doesn't know the difference is say someone saying some information is "CRAP" and "YOU ARE FULL OF CRAP" then I'm not sure there is anything to discuss further.

I'm and was when I posted "chilled" as one poster suggested and would turn that statement around when they feel the need to impose their personal feelings concerning who should chill out, take a chill pill, etc as bascially a "third party" to the discussion at hand and try impose their "posting standards" on someone else.

See there are always "two sides" to every coin;)
