I give every cleaner the same supply kit and my callback rate dropped fast
When I started I let cleaners bring whatever supplies they had at home. Every house got a different result. One cleaner used a great glass cleaner, another used paper towels and window cleaner on everything, and I had no idea which version of my service a client was judging me on.
Now every cleaner gets the exact same kit on day one. Microfiber cloths, an all purpose cleaner, a glass cleaner, a bathroom cleaner, a vacuum, a mop, a bucket, gloves, and trash bags. I buy it all in bulk so it costs me less than the random stuff they were buying themselves.
Two things changed. First, every home gets cleaned with the same products, so the quality is consistent no matter who shows up. Second, the mid job store runs stopped. Nobody texts me at 2 pm saying they are out of bathroom cleaner.
If your cleans feel uneven from one cleaner to the next, standardize the kit before you blame the people.
