I use Folex. It's in a while bottle with purple writing. I get it at Target. It's not advertised as far as I know. I use it on literally everything from clothing to carpet to car mats. So far it hasn't "ruined" anything and has removed everything.

I shampooed my carpeting a few weeks ago. Now, I see stains everywhere. I don't know if I removed a stain guard from the carpeting or what. But I wondered if you have had good experience with a brand of stain guard that I can spray on my carpeting now after cleaning it.

Okay....this recipe has been posted many times and I truly believe all of the accolades. It still makes me nervous, though. Why does the hydrogen peroxide that I use on my teeth and gums a couple of times a week bleach my towels if I'm careless but won't do the same to clothing, carpeting, etc.? Does the liquid detergent alter the chemical composition of the peroxide? Inquiring minds want to know, lol.

[Sigh] > my hardware store salesperson told me to spray polyurethane. Probably not the most brilliant idea. Not seeing it, I'd probably recommend scraping off the spots. If you don't have a finely tuned cabinet scraper, get some utility knife blades, dull the corners and hold them between your thumbs and index fingers. Tilt the blade about 10 degrees from vertical away from you and push lightly with your thumbs. You might need to adjust the angle a bit forward or backward to get a good cut. Then using a sanding block and 400 grit sandpaper, lightly dull the whole surface. Wipe off the sanding dust with a cloth dampened in mineral spirits. Wipe on another THIN coat of polyurethane, either a canned "wipe on poly" or regular poly thinned 50-50 with mineral spirits. Use a lint-free cloth or a blue shop towel. Did I say THIN coat? A better choice would have been to apply lacquer, as that's almost certainly what's on there now. It will bond to itself creating "one coat" of finish. But since you've applied the spray poly already, it's too late for that as the lacquer will be too "hot" for the poly and can blister it up.
