It was brought up to add the subject to the IICRC app but if I can't find Pemberton writing about it or anything on Google, is it a real issue?
but is it enough of an issue to warrant being in "the App"?
He quoted scripture today
This would have been for the Upholstery section, which I suspect would have been all the same issues.Not much of an issue today because the vast majority of the silicone carpet protector industry died from their yellowing issues. It wasn't the silicone itself, it was the added "UV blocker" that turned yellow and could not be removed.
I remember being told way back then that Fibreseal was changing over to fluorchemical back in the 80s due to these yellowing issues; many others just went out of business to avoid paying for all of the ruined furnishings.
I don't think anyone is adding UV blockers to silicone anymore, so the biggest problem with is applying it to fluorochemically treated fibers. It becomes a sticky mess that causes rapid soiling and requires the use of strong solvents to remove. Typically the carpet will have to be replaced.
I remember those. I tried it on auto carpet hoping to make it look better. It came out with a purplish tint.Same can be said for using cleaning products that contain optical brightners?
Certified brand used to sell optical brightner so you could add it to your cleaning solution.
Yep. I understand that Resolve stopped using them. It took a long time, so hopefully it cost them some money.Same can be said for using cleaning products that contain optical brightners?
