Worth waiting for.
Initially thought too much spray in a concentrated area. But slow and steady does it. spray about a meter at a time with a back & forth motion,
then do another meter. Careful not to over soak. Go back to the start and vacuum up soaked spray, do 2 meters at a time at carpet/wall crevice,
walla, did good. Easier than cleaning the lounge crevises with the vacuum cleaner.
