Review on Kevinrooty 50PCS Disposable Crevice Cleaning Brush Tool Kit, Disposable Toilet Brush, Blue Disposable Window Sliding Door Track Cleaner by Rodney Sample

I've used these grout cleaners for a few weeks but never found a need for them until I used a kitchen utensil to chop cucumbers and then removed the chopping disc to clean. There were no problems with the large round part of the disc. Running water and a sponge were enough. However, there is a gap less than 1/8 inch wide along the edge that needed to be enlarged. as the cucumber pieces would get stuck in there until removed with a damp grout brush. I have not used these brushes to clean the toilet. They are too small to clean the entire toilet and too big to be flushed down the toilet after cleaning a small spot. My wife used it to clean her old keyboard. It worked and the dirt was removed. My newer keyboards that were compressed air cleaned a year ago didn't foul the brush.
