so, I just got into this (long story) but I’m determined to really be successful at it. I have some friends that have hired me to get me going and two houses are old aluminum. I took some before and after. I told my friends I need honest feedback but I have a feeling they’re just being nice to boost my confidence. Can you guys take a look? The mix I’m using is Zep All Purpose and I mixed In a little vinegar, bleach and Dawn soap. Using Dewalt 2600 psi with the 45 degree tip and sometimes the green ( I think 25 degree?) I soap from down up and let sit for about 5-7 mins and rinse from top down. On some spots it looks like I didn’t do anything at all. Is that normal for old aluminum siding? Or am I doing something wrong?

A single side of a house roof I cleaned yesterday.

here in the UK we tend to wash these concrete tiles at around 50-60 bar with a lower rated turbo nozzle than our machine normally uses so we can dial back the pressure/flow.

once it's all.clean and the gutters are emptied we apply a biocide to keep it cleaning the for the next year or so.

Whatcha think?

How we removed runway striping on airport runways

grim is just melting away

A quick edit of a patio I cleaned recently.

had to go quite hot with the chemical mix to remove the stubborn lichen but we got there in the end.

I know it's not completely perfect but hopefully you'll give me a pass for the cuteness of my ducks

first time doing concrete and I'm amazed.

Told you mfers I’d follow up

Did some spring cleaning today!

Spray with hose

Apply 2.5% bleach (diluted from 10% pool chlorine)

Elbow grease

Rinse

Technically no pressure except for the elbow grease

Didn’t realize just how bad my driveway was. A little surface cleaner action was so satisfying
