| Pressure washers - good or bad?
the hand-held high pressure washers you can buy from halfords & B&Q seem to be growing in popularity but are they a good idea for cleaning your pride & joy? the pressure they put out is very high & it seems to me that they would strip wax off at best & damage paint at worst. These things can strip a years worth of mildew & moss off concrete in one pass.
Does anyone have any experience of using these? is the pressure variable on the better ones? |
