The Squire had to work on the tractor yesterday afternoon, so he blew all the peanut shells of the carport to have a clean place to lay down. While he was hard at work I decided to use the blower to remove the peanut shells from the walk in front of the den and up toward the driveway from the front door.
I nearly lost my footing going up the walk; the constant water from the spring had caused algae to grow on the concrete, and it was slicker than greased glass. I turned on the hose and got the push broom, but I really didn’t make much headway. I had a little bit of old dish soap – some cheap stuff I had gotten at the dollar store – under the sink, so I squirted that over the walk and had at it again with the broom and the hose.
What a monster I created! Only a little bit of soap – no more than I use in a dishpan – and I had suds up to my knees! The Squire came out and used the broom while I squirted, and between us we managed to get the entire walkway pretty well cleaned up. We even moved the welcome mats and cleaned under those, while we were at it.
And in a week it will probably be as bad as it was before we started.

Perhaps you can spray the walkways down with a dilution of water to either vinegar or bleach to retard the growth?
That is an excellent idea! We’re supposed to have thunderstorms off and on all week, but I will absolutely try it next week. No point in applying it and then having it washed off right away.
So true when you say it will be back to square 1 after a week! Yet we still maintain our cleaning regime. I feel you my friend!
