Of all the toilet tissue varieties available, which type is best for use in RVs? Your safest bet is to forgo quilted, scented, double-ply or dyed versions in favor of white, unscented, single-ply toilet paper. Single-ply paper disintegrates faster than two-ply, three-ply or quilted tissue in your holding tank, thereby helping to avoid clogged dump valves and fouled sensors that produce faulty tank-level readings. As for dyed, bleached or scented tissue, the chemicals used in these products can destroy the bacteria that break down solids in septic tanks. You can purchase toilet paper that is labeled “green” or made specifically for RVs, though other readily available options — like classic Scott® white one-ply tissue — are equally suitable. To test your toilet paper for RV use, place a couple of sheets in a covered jar of water and shake. If the paper disintegrates quickly, it’s OK to use in your RV.
