I have auto-cover over my indoor pool. The cover is on rails and can be safely walked on. I have cleaned the cover with a bucket and rag or mop several times with a dilute bleach solution. Can I use a commercial product and a power washer to do the same job. I was looking at a product made by Zinsser called JOMAX (made for power washing a house), you add 3/4 of that (The ingredients are: O-phenylphenol, sodium salt 0.25% and Inert ingredients 99.75%), 2 cups of bleach and 3 qts. water.
