Bicast - Perfumy odor/scent - how to remove?

[Roger Koh]

This 60ml Prep-7.7 is not custom pack to cover your couch, it will do the job to remove surface contamination, try out only on one cushion, you would know how much time is required for your specific situation. Refills are available in bigger packing.

Then let me ask -- how much Prep-7/7 would you expect to need for a couch? Is there a chance the small bottle is enough? I'd rather not have to do all three steps in two separate installments!

[Roger Koh]

1gm of Prep-7.7 when works with horsehair Brush-1 covers 1 square foot.
Therefore 60gm will covers 60 square feet of surface area.
What is the total surface area you want to cover, will work out accordingly!

[Emerson]

OK -- well, luckily enough, right around 60 sq. feet. I take it the bottle is 60 gm? And I need to work it with horsehair brush? At one point above, you said simply coat using the foam brush (post #7). Thanks!

[Roger Koh]

You will lose 0.5gm to the Brush-1 - lighter before use and heavier after use.
You will probably loose much more when using the foam Brush-3" - so less coverage as the foam brush is heavier after use.
The seams will also takes more as compare to a flat surface.

OK, I'm through one good pass with the Clean 3.8. The towel comes off clean but there are still some sticky/tacky places. As I still have some of the Clean left, should I go over it again? Most places were done twice with the Clean, not all. Or can I just trust the Rinse step to get the rest out?

BTW, I did have just enough of the Prep to cover the couch, with about 1/3 teaspoon left. Had to stretch it, but got a sticky-ness everywhere.

Thanks!

The sequence is Prep-7.7 > Clean-3.8 > Rinse-3.0.

>>> As I still have some of the Clean left, should I go over it again?
Yes, to remove the sticky residue.
