I bought one too,it works well for me also,when I ran out of mr.clean soap once,I just washed my car old way,(you cannot put other soap in mr.cleani was surprised how well this thing works. i bought the deluxe one from kmart. i think it was priced wrong. it came to $11.00 the regular one was 17 bucks. it worked well on my caddy, which is silver. so i tried it on my pacifica, which is black and it dried w/o spots.
dispenser)and rinsed it with mr. clean filtered water,it worked fine,it's the filter that prevents the water spots as it deionizes the water.
