So....I bought one of the Karcher pressure washers that Costco had on sale last month. On reading the manual I see that if I don't use their proprietary detergents, my roof will cave in, my cats will die, yada yada... The questions are, (1) Are Karcher products available in the lake Chapala area? (I know where their store is in Guadalajara) and (2) does anyone have experience using non-Karcher detergents in a sprayer? if so, what do you use & and what ratio of detergent to water seems to work?
I use a Karcher pressure washer at out house in PV to clean the mold off the terrace tiles. I never use detergent, just water. Try just water first. I also use the optional rotary nozzle as it cleans well and there is less chance of damaging softer tiles.
