It is has yellow stains  which I thought would be an easy fix with strong detergents.  

For units with dishwashers, I provide a small bucket of dishwasher detergent pods with a warning not to use regular dish soap in the machines.

I purchased a cheap Amana a few years ago and the detergent dispenser no longer works.

On the topic of cabinets.... pro tip:  If it's going to be a rental, take a vinyl flooring remnant and line the base cab under the sink to protect the case from the inevitable drip or leaking detergent container.Hope this helps.

Unless you're consistently finding product packaging in the refuse you can use to gauge consumer preferences, it might be only a marginal idea.Maybe consider posting a survey in the laundry room asking for the tenants' feedback: "Would you find a laundry detergent vending machine helpful?" 

The bleach and some detergents can break down the shingles even further.

Lower pressure and/or unheated or lower temp you may need a detergent to get all chaulk off.

If the worst thing is that they stole your laundry detergent, then you can solve the problem in the future.

Anything will chemicals, detergents, carpet, drape, new car seats can cause more health discomfort and Feds have not tackled them yet. 

They will also remove any affected materials that cannot be treated with detergent/water solution.Once the remediation work is completed, have the mold inspection company come back out for a re-test.
