On a tour of Spain and have been struggling to get normal toilet chemicals so found instablue.
I believe it is having no effect at all, tried the stated dose and double the dose but still awful.
Has anyone tried it and am I doing something wrong?
Use mine for "solids", normally in toilet tent or awning. If just for a night time wee a bucket "unisex" or if solo a detergent bottle (empty)!
I don't think the solids will break down completely if only in the holding tank a day or two. Give the tank a shake before emptying.
