CCHSNC 14 Report post Posted August 19, 2003 anyone?? yes no? I think it can because I think it is a percarb??? I haven't used the efc-38 but would like to get some and would like to know if it has multi uses. Share this post Link to post Share on other sites
Brian Keating 14 Report post Posted August 19, 2003 On The Grime Scene website it says it will clean concrete, brick, wood/vinyl siding, fiberglass, canvas, metal, wood decks and even carpet. No mention of Asphalt singles. I believe you are right about it being a percarb since it is only good for about an hour after mixed. Call Beth. Share this post Link to post Share on other sites
Beth n Rod 1,279 Report post Posted August 19, 2003 Yes, you can. EFC-38 is a percarb but also a light duty stripper. It has a life of a couple of hours after mixing so mix as needed. Beth :groovy: Share this post Link to post Share on other sites
Paul B. 523 Report post Posted August 19, 2003 If you are looking to eliminate mold and mildew, the most effective and least damaging chemical is Sodium Hypochlorite (bleach). Sodium Hydroxide based products will also kill mold and mildew, but I personally think they can harm the asphalt shingles. Copper and Zinc based products also work well on mold & mildew.

CCHSNC 14 Report post Posted August 20, 2003 Paul you are correct SH will/can damage ashalt shingles that's why I don't want to use it. I know it is the most widely used chem. for cleaning roofs but to me it's not worth the risk. Share this post Link to post Share on other sites
Guest rfitz Report post Posted August 20, 2003 I know Steve Rowlette sells a product specifically for that called Roof Magic, you may want to take a look at that, EFC is a great cleaner, I use it all the time, probably every week, but it isnt that great on mold and mildew..

One Tough Pressure 580 Report post Posted August 20, 2003 Roof Magic is a Sodium Hydroxide based product and what he wants to avoid. Just because someone sells it, does not mean it is the right thing. Share this post Link to post Share on other sites
Guest rfitz Report post Posted August 20, 2003 Envirospec, sells a environmentally safe product called Restore, that is supposed to be the best on the market for asphalt shingles, it is a #1 on the MSDS safety sheet, maybe try that..? it also kills mold and mildew and contains no bleach...
