Tried it out this morning on my dogs' high traffic/slobber area, worked well! DIY grout cleaner, 5'x6' area. 1/4 cup bleach & 3/4 cup baking soda to create a nice thick paste.Use an old toothbrush and scub. Let it sit for ten minutes, then wipe clean with a rag and hot water (rinse rag constantly).
THE BASIC RULES FOR CLOTHESLINES - Great read The only one I'd change is that I do hang pants by the waistband - across 3 sets of lines to get the best draft to them to help them dry faster (we don't bother with creased legs)
